What this adds

The Custom OpenAI Compatible provider can now send user-supplied HTTP headers
with both chat completions and /models requests.

Gateways and self-hosted endpoints routinely need headers the app cannot know
about — Portkey routing (X-Portkey-Config), Cloudflare Access
(CF-Access-Client-Id), LiteLLM, corporate proxies, tenant/attribution headers.
Without this, those endpoints are simply unusable.

In Settings → Custom OpenAI Compatible, a new CUSTOM HEADERS (OPTIONAL)
editor takes one Name: Value pair per line:

# routing for the gateway
X-Portkey-Config: pc-abc123
CF-Access-Client-Id: 0123.access

Design notes

Fail-closed parsing. A line is either sent or reported with a reason in the
editor — never silently dropped. Blank lines and #/; comments are ignored;
the value keeps everything after the first colon (URL values work); malformed
names, missing values, >8 KB values, embedded line breaks, case-insensitive
duplicates, and a 32-header cap are each refused with a specific message.

App-managed headers cannot be replaced. Authorization (the resolved API
key), Content-Type, Content-Length, Host, Connection,
Transfer-Encoding, Cookie, and Accept-Encoding are rejected at parse time
and re-checked at transport time, so even a forged transition list cannot
clobber the credential.

Encrypted at rest. A header block routinely carries a gateway token, so it is
stored as an AES-256-GCM envelope in ProviderCredentialStore under its own
credential family (ProviderCredentialId.CustomHeaders), bound to the provider
through the credential-ID AAD. SettingsRepository commits the encrypted record
and strips the LLMConfig field in the same transaction; blocks written by
earlier builds are migrated into the Keystore on launch, and a storage failure
leaves the plaintext as the retryable source instead of losing the headers.

Redaction. Header values of 8+ characters are registered with
SecretRegistry, so a gateway token echoed back in a provider error body is
redacted exactly like an API key. Values are bullet-masked in Settings until the
user taps Show values.

Files

  • core/llm/CustomHeaderRules.kt — new parsing/validation/transport rules
  • core/llm/providers/CustomOpenAIProvider.kt — applies headers to the request
  • core/llm/ModelFetcher.kt — same headers for /models, so the picker works
  • core/llm/LLMProviderFactory.kt — resolves headers into the request config
  • data/repository/SettingsRepository.kt — encrypt-and-strip, hydration, migration
  • core/security/ProviderCredentialStore.kt — new credential family
  • ui/screens/SettingsScreen.kt, ui/viewmodel/SettingsViewModel.kt — editor
  • app/lint-baseline.xml — one refreshed entry (see below)

Verification

  • ./gradlew :app:assembleDebug — BUILD SUCCESSFUL
  • ./gradlew :app:testDebugUnitTest — 589 tests, 0 failures, of which 52 are new:
    CustomHeaderRulesTest (28 cases: parsing, reserved names, injection attempts,
    masked-value rejection, masking, redaction thresholds), HeaderValuesVisualTransformationTest
    (9 cases: per-line masking, length preservation, real values never rendered),
    7 new credential-store cases (ciphertext at rest, AAD binding across providers,
    tamper rejection, enumeration, reset), 5 new repository cases (encrypt-and-strip,
    hydration, plaintext migration, retryability), and 3 new MockWebServer cases proving
    headers reach the wire, that Authorization survives a user attempt to replace it,
    and that a gateway token is redacted from a 403 body.

Fixed during review: the mask could become the header value

The first version of the editor assigned the masked text to the text field's own
value. That makes the mask the data — the first keystroke in masked mode replaced
the real block with bullets, which were stored and sent, and the request then failed
with unexpected char 0x2022 in CF-Access-Client-Id value. Reported by a user
running the built APK.

The second commit masks through a VisualTransformation instead, so the field's
value is always the real block and only the rendered glyphs change. It also refuses
masking characters (bullet, non-breaking space, zero-width space, BOM) in
CustomHeaderRules, so such a value is reported in the editor rather than reaching
the network as an opaque OkHttp error.

Note for the reviewer: a header block already saved by the first version holds
bullets and must be re-entered — the editor now shows a warning saying exactly that.

Note on lint: CI runs lint with abortOnError + warningsAsErrors, and it
already fails on main today — I measured 40 errors at 6ff5a06, all
pre-existing (DefaultLocale in SocialActions.kt, SocialCharts.kt, and the
social screens). This branch measures 39, i.e. one fewer. I refreshed one
existing baseline entry in app/lint-baseline.xml because my SettingsViewModel
edits shifted a previously-baselined ObsoleteSdkInt finding down ~46 lines and
lint re-reported it as new; I edited that single coordinate rather than
regenerating the file, per the shrink-only policy in app/build.gradle.

Scenarios Tested

# Scenario Result Notes
1 Configured headers are sent with POST /chat/completions ✅ Pass Asserted on the wire via MockWebServer (CustomOpenAIProviderNetworkTest)
2 Configured headers are sent with GET /models ✅ Pass Same resolution path as completions (ModelFetcher)

6 Pasted CRLF cannot inject a header into another value ✅ Pass Line split on \n; \r inside a value is refused
7 Header block is encrypted at rest and absent from the DataStore JSON ✅ Pass Envelope assertions; JSON asserted free of the token
8 Block survives a restart and is re-read from the Keystore ✅ Pass Hydration path in SettingsRepository
9 Pre-existing plaintext blocks migrate to the Keystore ✅ Pass Committed before the plaintext is stripped
10 Gateway token echoed in an error body is redacted ✅ Pass SecretRegistry registration on 403 response
11 Values are masked in Settings until revealed ✅ Pass HeaderValuesVisualTransformationTest (9 cases)
12 A masked value cannot reach the wire or be stored ✅ Pass Parser + transport guard; 5 cases pinning the reported failure
13 Debug APK builds and the app launches ✅ Pass APK built successfully; ran on device

How to test it manually

  1. Settings → select Custom OpenAI Compatible, set the base URL.
  2. Add a header line, e.g. X-Test-Header: hello.
  3. Tap Test Connection and confirm the gateway receives the header (check the
    gateway's request log).
  4. Type Authorization: Bearer attacker and confirm a warning appears under the
    editor and the request still carries your API key.
  5. In masked mode, add a second line and confirm the first value is not replaced
    by bullets (this is the regression that was fixed).
  6. Restart the app and confirm the block is still there, masked.

Notes for reviewers

  • LLMConfig.customHeaders still exists but is migration input only — it is
    never trusted ahead of the Keystore, and is documented as such.
  • CustomOpenAIProvider reads the new llmConfigForProviderRequests flow because
    it fetches the repository directly rather than through WrappedLLMProvider;
    every other provider is unchanged.
  • Reviewed against docs/CONTRIBUTING.md: branch named descriptively, build run,
    test report above. Scenario Welcome to opendroid Discussions! #4 ("Your Custom Feature") is covered by the table.

Summary by CodeRabbit

  • New Features

    • Added custom HTTP header support for Custom OpenAI Compatible endpoints.
    • Configure headers in Settings using one Name: Value entry per line for chat and model-list requests.
    • Header values are masked and securely stored.
    • Invalid, duplicate, reserved, malformed, or unsendable headers display warnings.
    • Off-device cleartext endpoints are refused; local-device endpoints remain available with an informational notice.
  • Security

    • Custom endpoint redirects are refused to prevent credential forwarding.
    • Gateway token values are redacted from provider errors.
  • Documentation

    • Documented configuration, validation, security, migration, and encrypted storage behavior.

Gateways and self-hosted endpoints (Portkey, Cloudflare AI Gateway, LiteLLM,
corporate proxies) route or authenticate on headers the app cannot know about,
so the provider now accepts a user-supplied header block.

- Add CustomHeaderRules: parses a `Name: Value`-per-line block fail-closed with a
  per-line reason, so a line that cannot be sent is reported in Settings instead
  of being dropped silently. Blank lines and `#`/`;` comments are ignored, values
  keep everything after the first colon, and a line break can never ride inside a
  value.
- Send the headers with chat completions and with `/models`, so the model picker
  works against the same gateway. Authorization, Content-Type, Content-Length,
  Host, Connection, Transfer-Encoding, Cookie, and Accept-Encoding cannot be
  replaced, enforced both at parse time and again at transport time.
- Store each provider's block as an AES-256-GCM envelope in
  ProviderCredentialStore, bound to the provider through the credential-ID AAD.
  SettingsRepository commits the encrypted record and strips the LLMConfig field
  in the same transaction, and migrates blocks written by earlier builds into the
  Keystore before removing the plaintext, so a storage failure stays retryable
  rather than losing the headers.
- Redact header values from provider error text via SecretRegistry, and mask
  them in Settings until the user reveals them.
- Add Settings editor plus CustomHeaderRules, credential-store, repository, and
  MockWebServer coverage (575 unit tests pass).

Also refresh the one lint-baseline entry whose line number moved in
SettingsViewModel.kt; the finding itself was already baselined.
… values

Masking a text field by assigning masked text to its `value` makes the mask the
data: the first keystroke in masked mode replaced the real block with bullets,
which were then stored and sent as a header value. OkHttp rejected the request
with an opaque `unexpected char 0x2022 in CF-Access-Client-Id value`, so a
configured custom endpoint became unusable.

- Mask through `HeaderValuesVisualTransformation` instead, so the field's value
  stays the real block and only the rendered glyphs change. The transformation is
  length-preserving, which makes `OffsetMapping.Identity` exact, so the caret
  still lands where the user expects on every line.
- Refuse masking characters in `CustomHeaderRules.parse` and `isTransportable`, so
  a value carrying a bullet, a non-breaking space, a zero-width space, or a BOM is
  reported under the editor with instructions instead of reaching the wire as an
  OkHttp error. Those characters can never be part of a legitimate header value
  here, and the same guard covers a paste out of another app.
- Correct the KDoc that claimed the mask was display-only; it was not.
- Add coverage: `HeaderValuesVisualTransformationTest` (9 cases — masking per
  line, length preservation, comments and empty values left alone, the real value
  never rendered) and 5 parser cases pinning the exact reported failure, including
  one asserting a masked value is neither sent nor registered as a secret.

589 unit tests pass. Lint still measures 39 errors against 40 at HEAD.
The header editor built a new HeaderValuesVisualTransformation on every
recomposition, so each keystroke re-masked the whole block for a fresh instance.
Hold it in `remember` instead. Behaviour is unchanged.
The editor capped the field at 8 lines, so a longer block became an
auto-scrolling box: with the caret at the end, the visible window shows the tail
of the block, which reads as "Show values only reveals the last line". Drop the
cap and let the field grow with the block; the enclosing list already scrolls.

Pinned with two multi-line cases: every line masked in a 5-line block, and blank
or trailing lines preserved rather than collapsed.

Walkthrough

Custom OpenAI-compatible endpoints now support validated, masked, Keystore-backed custom HTTP headers. Chat and model-list requests use these headers, reject remote cleartext HTTP and redirects, and redact sufficiently long header values from provider errors.

220-228: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Cancel pending custom-header persistence during credential reset.

SettingsScreen keeps the custom-header editor available during recovery. If the user enters a header and selects resetProviderCredentialsForReentry() before the one-second delay expires, customHeadersJob remains active. It can read _customHeaders and call settingsRepository.updateCustomHeaders() after the reset, restoring the pre-reset header. Cancel customHeadersJob and clear _customHeaders before starting the reset.

Four of the seven review findings were real; each fix is paired with a test.

- Reject characters OkHttp cannot transport (control characters, DEL, non-ASCII)
  in parse() and isTransportable(). Request.Builder.header throws
  IllegalArgumentException while the request is being built, which reached the
  user as an opaque failure instead of a correctable line. addUnsafeNonAscii is
  deliberately not used: RFC 7230 says new fields SHOULD stay US-ASCII, and raw
  bytes only work if the server happens to agree.
- Refuse redirects for custom-endpoint requests, in both the provider and the
  model-list fetch. Measured: the shared client drops Authorization when a
  redirect crosses origins but forwards arbitrary custom headers, so following
  one handed the gateway token to whatever host the redirect named.
- Stop falling back to the persisted plaintext header copy when the credential
  store read fails. An unreadable/tampered record must not silently downgrade to
  the stale copy; this is the same Zero Plaintext Fallback the API keys follow.
- Mask a header line that has no colon, so deleting the colon from
  "X-Token: secret" no longer leaves the value readable.
- Propagate the migration strip failure instead of reporting success, and correct
  the README/RELEASE claims about plaintext lifetime and redaction coverage.

The claim that startup migration tombstones the records it just wrote was checked
with a test and does not reproduce: removals are computed against the credential
snapshot, which already contains those records, so the removal set is empty.

596 unit tests pass.
The header editor debounces its save by a second, so a job already in flight could
run after resetProviderCredentialsForReentry() cleared the store and write the
pre-reset block straight back in. Cancel the pending API-key and header writes and
clear the in-memory copies before the reset begins, so nothing can be restored
behind the user's back.

The concern is supported: SettingsViewModel assigns the result of readCustomHeaders() directly to _customHeaders, while SettingsScreen renders CustomHeadersEditor without disabling it during hydration. An edit made before the read completes can therefore be replaced by the older snapshot and later persisted. Preserve edited values during hydration or block editing until hydration completes.

Serialize startup credential migration with custom-header saves.

SettingsRepository.init launches updateConfig { it } without coordination. That call can merge legacy plaintext block A, then updateCustomHeaders can write newer block B before storeSecretsAndStrip writes A. The startup write can therefore overwrite B. DataStore.edit serializes preference edits, and ProviderCredentialStore locks individual calls, but neither spans this cross-store sequence.

Use one repository-owned mutex across the complete credential snapshot/write sequence in updateConfig, migratePlaintextCustomHeaders, and updateCustomHeaders. Add a controlled interleaving test; current tests are sequential or wait for migration completion.

Three fixes and one documentation correction, each verified against the code.

- Warn when the custom endpoint is not https. The app's network security config
  already blocks cleartext for everything except localhost/127.0.0.1/10.0.2.2, so
  a remote http:// endpoint cannot be reached at all; the real exposure is a LAN
  or scheme-less host, which formatBaseUrl defaults to http://. Rejecting http
  outright would break the self-hosted gateways this feature exists for, so the
  editor states the exposure instead of hiding it. The rule lives in UrlUtils next
  to formatBaseUrl so it tracks the URL the provider actually builds, and is
  unit-tested (a scheme-less host counts).
- Order the credential reset after pending writes instead of racing them: cancel
  *and join* the pending credential jobs before resetting, because a job already
  past its delay is inside the repository's synchronous write where cancellation
  no longer applies.
- Bound both takeRequest calls in the redirect test, so a regression fails it
  instead of hanging it.
- Correct the release/security docs: the encrypted write and the config strip are
  ordered writes with best-effort in-process rollback, not one cross-store
  transaction. A process stop between them can leave both copies on disk, and reads
  resolve that by trusting the encrypted record.

601 unit tests pass.

356-376: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Serialize custom-header migration with editor saves.

migratePlaintextCustomHeaders() reads a DataStore snapshot before calling providerCredentialStore.writeCustomHeaders(). The debounced SettingsViewModel.updateCustomHeaders() path can reach SettingsRepository.updateCustomHeaders() during this interval and write newer text first. Migration can then write its stale snapshot last and overwrite the edit. The credential-store lock serializes each write but not the migration read-write sequence.

Use one repository-level lock for the migration read, credential write, and DataStore strip, and acquire it in updateCustomHeaders() as well. A DataStore recheck alone cannot detect this editor save because the editor writes the credential store.

Comment thread app/src/main/java/com/opendroid/ai/core/util/UrlUtils.kt Outdated
The raw-text check was wrong in both directions. formatBaseUrl strips whitespace
mid-string, so "https: //gateway.example.com/v1" is sent over https and was being
flagged as cleartext; and it defaults a missing scheme to http://, which the raw
check only caught by accident.

Classify the URL formatBaseUrl actually returns, so the warning tracks the request
the provider will make. Add regression cases for both directions plus a trailing
slash, taking UrlUtilsTest to 7 cases.
Resolves the CWE-319 review finding. Credentials no longer travel in the clear to
another host, while the self-hosted case that the app's own network security config
blesses keeps working.

- UrlUtils gains sendsCleartextOffDevice/allowCleartextTransport: localhost,
  127.0.0.1, and 10.0.2.2 are local (traffic never reaches a network, and
  network_security_config.xml permits cleartext for exactly those); every other
  http:// endpoint, including scheme-less input that formatBaseUrl turns into
  http://, is refused.
- CustomOpenAIProvider refuses such an endpoint before building the request, so the
  API key and any custom-header value cannot leave the device. It fails with a typed
  RequestInvalid rather than letting OkHttp fail at connect time with its own
  cleartext-policy error.
- ModelFetcher applies the same rule to the /models request, which carries the same
  credentials, and reports why.
- Settings distinguishes the two cases: a refusal that names the fix, and an
  informational note for the permitted local-cleartext setup.

Tests: UrlUtilsTest covers allowed local hosts, refused off-device hosts (including
scheme-less input), https on any host, and blank input;
CustomOpenAIProviderCleartextTest proves no request reaches a refused endpoint and
that a loopback cleartext endpoint still proceeds. 609 unit tests pass.

official Android documentation 10.0.2.2 emulator alias physical device networking

💡 Result:

<search_synthesis>
In official Android documentation, the IP address 10.0.2.2 is defined as a special alias for your host machine&#39;s loopback interface (127.0.0.1) [1][2]. This address allows an Android emulator instance to access services (such as web servers) running on your development machine [1][3]. Key characteristics regarding this address include: - Emulator Specificity: The 10.0.2.2 alias is specific to the Android emulator environment [2]. It does not function as a loopback alias on physical Android devices [4][5]. - Network Isolation: Each emulator instance runs behind a virtual router that manages its own 10.0.2/24 address space [1][6]. The emulator is isolated from the development machine&#39;s network interfaces, which is why this special alias is required for the emulator to communicate with the host [1][3]. - Limitations for WebView: Official documentation notes that using 10.0.2.2 is not recommended for WebView debugging [7][8]. Because the WebView does not recognize this IP address as a secure context, certain web features—such as Service Workers, Geolocation, and access to hardware like cameras or microphones—may be disabled [7][8]. For physical devices, or when a secure context is required in a WebView, the recommended approach is to use the Android Debug Bridge (adb) to set up reverse port forwarding [7][8]: adb reverse tcp:DEVICE_PORT tcp:HOST_PORT This command forwards a specific port on the device to a port on your host machine, allowing you to connect to local services using localhost on the device itself [7][8].

The emulator provides versatile networking capabilities that you can use to set up complex modeling and testing environments for your app. This page introduces the emulator network architecture and capabilities. The virtual router for each instance manages the `10.0.2/24` network address space. - All addresses managed by the router are in the form of `10.0.2.xx`, where `xx` is a number. The following table shows how addresses within this space are pre-allocated by the emulator or router: | Network Address | Description | | --- | --- | | 10.0.2.1 | Router or gateway address | | 10.0.2.2 | Special alias to your host loopback interface (127.0.0.1 on your development machine) | | 10.0.2.3 | First DNS server | | 10.0.2.4, 10.0.2.5, 10.0.2.6 | Optional second, third, and fourth DNS servers | | 10.0.2.15 | The emulated device network when connected using ethernet | | 10.0.2.16 | The emulated device network when connected using Wi-Fi. | | 127.0.0.1 | The emulated device loopback interface | Note: After Android Emulator version 36.5: When multiple emulated devices are connected using Wi-Fi, they are assigned addresses starting with `10.0.2.16`, `10.0.2.17`, and subsequent addresses. Note: In Android Emulator versions earlier than 36.5, each instance of the emulator runs behind a virtual router or firewall service that isolates it from your development machine network interfaces and settings and from the internet. An emulated device can&`#39`;t detect your development machine or other emulator instances on the network. It detects only that it is connected through ethernet to a router or firewall. Besides Wi-Fi, the same address assignments are used by all running emulator instances when connected using ethernet. This means that if you have two instances running concurrently on your machine, each will have its own router, and behind that, each will have an IP address of `10.0.2.15`. The instances are isolated by a router and can&`#39`;t detect each other on the same network. For information about how to let emulator instances communicate over TCP/UDP, see Interconnect emulator instances. The address 127.0.0.1 on your development machine corresponds to the emulator&`#39`;s loopback interface. To access services running on your development machine loopback interface, use the special address `10.0.2.2` instead. The pre-allocated addresses of an emulated device are specific to the Android Emulator and are likely to be different on real devices (which are also likely to be network address translated, specifically behind a router or firewall). ## Local networking limitations Android apps running on an emulator can connect to the network available on your workstation. However, apps connect through the emulator, not directly to hardware, and the emulator acts like a normal app on your workstation. This can cause some limitations: - Communication with the emulated device might be blocked by a firewall program running on your machine. - Communication with the emulated device might be blocked by another (physical) firewall or router where your machine is connected. The emulator&`#39`;s virtual router can handle all outbound TCP and UDP connections and messages for the emulated device, provided your development machine&`#39`;s network environment allows these connections. There are no built-in limitations on port numbers or ranges, only those imposed by your host operating system and network. Depending on the environment, the emulator might not support other protocols, such as ICMP, which is used for "ping". The emulator does not support IGMP. For example, users cannot use the ping command to ping the host machine or other devices on the Local Area Network.

Then, configure the networkSecurityConfig property on the application node in the Platforms\Android\AndroidManifest.xml file in your .NET MAUI app project: ... ```xml <?xml version="1.0" encoding="utf-8"?> <manifest> <application android:networkSecurityConfig="`@xml/network_security_config`" ...> ... </application> </manifest> ... the Androi…[truncated] <title>Does 10.0.2.2 work on physical device?</title> https://stackoverflow.com/questions/26362894/does-10-0-2-2-work-on-physical-device # Does 10.0.2.2 work on physical device? - Tags: android, timeout, xmpp, adb, asmack - Score: 3 - Views: 3,146 - Answers: 2 - Asked by: tomm (302 rep) - Asked on: Oct 14, 2014 - Last active: Feb 6, 2025 - License: CC BY-SA 3.0 --- ## Question I can&`#39`;t connect to my local xmpp server while debugging from my LG L9 phone (Android 4.1.2) connected via USB.

Can this loopback address be used on physical device too or is it available just for emulator? --- ## Accepted Answer — Score: 2 - By: tomm (302 rep) - Answered on: Oct 14, 2014 So, i tried to connect with 10.0.2.2:5222 from emulator to Openfire (xmpp server) running on my laptop (localhost) and it WORKS! So yes, 10.0.2.2 only works with android emulator, not physical device connected via usb. If somebody wants to use physical device, he needs to create LAN (where xmpp server is connected) and connect traditionally with WiFi (so USB cable do not provide network connection between phone and computer, to which the phone is connected). --- ## Answer 2 — Score: 0 - By: Jeroen Landheer (10,191 rep) - Answered on: Feb 6, 2025 This is rather an old question, but since there&`#39`;s a lot of people still searching for this, here is a way to connect to your local machine using a USB cable. Once you have connected your device, you can use the `adb` command to forward a port on the device back to your dev machine. (`adb` is part of Google&`#39`;s Android SDK.) This allows you to connect it to a development web server or something else. The steps you can take are: 1. Make sure your device has USB debugging enabled and is connected to your PC. 2. List the device(s) you have connected with `adb devices` 3. Forward a port from the device to your dev machine with `adb -s reverse tcp: tcp: ` Example: ``` > adb devices List of devices attached R52NB0A8LHD device > adb -s R52NB0A8LHD reverse tcp:2222 tcp:2222 2222 ``` After this you can connect to `localhost:2222` on the device and it will forward that port to your dev machine. <title>Connection to LocalHost/10.0.2.2 from Android Emulator timed out</title> https://stackoverflow.com/questions/35441481/connection-to-localhost-10-0-2-2-from-android-emulator-timed-out # Connection to LocalHost/10.0.2.2 from Android Emulator timed out Tags: java, php, android, post, localhost - Score: 20 - Views: 64900 - Answers: 6 - Answered: yes - Asked by: Saumik Bhattacharya (1051 rep) - Asked: 2016-02-16 - Edited: 2017-05-23 - Site: stackoverflow ## Question Although this question has been asked multiple times in StackOverflow and I went through many of them, still I couldn&`#39`;t resolve my issue or I am not able to find out the root cause of the issue.

Please note I am using Android Studio for my build. Thanks in advance! ## Answers ### Answer by Saumik Bhattacharya (score: 12 [ACCEPTED]) I have figured out the reason why it was not working. There were two issues -- The IP Address was not correct. So I changed the IP Address from 10.0.2.2 to the IPv4 address - which can be obtained on windows by typeing ipconfig in the command prompt and see link for linux. Also the port number 8080 was not correct. I have set my own port number in httpd.conf file, like ##Listen 12.34.56.78:8383Listen 0.0.0.0:8383Listen [::0]:8383##, under Apache and I used the same. After changing both and re-starting the WAMP server, it worked like a charm. ### Answer by styssi (score: 11) Making a connection from your Android to your Computer is working with 10.0.2.2 only on an Google Android Virtual Device. Android Virtual Devices are listening for 10.0.2.2 and forwarding all the requests to your computer. Genymotion Android Virtual Devices are listening on 10.0.2.3 and forwarding those requests to your computer. 10.0.2.2 is not working with your real Android device. If you want to use it with your real device you have to set the IP of your computer, as it has been suggested by a previous answer. ### Answer by Roger (score: 3) Accepted answer to this question is really unclear so maybe this will help someone. Just got the same problem and resolved it by executing "adb reverse tcp:8080 tcp:8080", although after I revoked forwarding, the host machine remained visible and all ports were working, so it is unclear how it works. Make sure that you have no proxy in wifi settings if you have, then 10.0.2.2 is added to bypass without mask that you didn&`#39`;t make a typo, sometimes people put 0 instead of 2 like this 10.0.0.2:8080 ### Answer by Zafar Imam (score: 1) Why to go f…[truncated]

Sensitive Data Exposure

Reachability: External
Exploitability: Moderate
CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Restrict the 10.0.2.2 cleartext exception to emulator execution. Android defines this address as an emulator alias, and real devices can resolve it differently. The unconditional allow-list can send API keys and custom headers over HTTP on physical devices. Remove the exception or gate it on verified emulator detection, and update the Settings message and tests accordingly.
