Duplicate value for ressource

[wharnisch]

When using google library 'com.google.android.material:material' in a project also using RichTextEditor library, the following error is thrown when building the project if version number of android.material:material is higher than 1.3.0 (actual stable version is 1.6.1):

Duplicate value for resource 'attr/dividerColor' with config 'DEFAULT' and product ''.

I tried to solve the problem myself in RichTextEditor source, but when importing RichTextEditor in my Android studio there are lots of gradle errors I can not solve.

Please help, I really need help,
as I am using this library for my android app 'Rich Text Notes' and I can not update the app any more because of this problem.

Have you found any solution to this issue?
I am also having the same problem as you.

I have downloaded this lib as a module and removed unnecessary code like the JVM module and combined android and common modules in a single module. trying to solve this issue but didn't get lucky to solve this issue yet
still getting this problem

Execution failed for task :app:mergeDebugResources.
A failure occurred while executing com.android.build.gradle.internal.res.ResourceCompilerRunnable
Resource compilation failed (Failed to compile values resource file C:\Users\Patel\Desktop\android\RichTextLib\app\build\intermediates\incremental\debug\mergeDebugResources\merged.dir\values\values.xml. Cause: java.nio.file.InvalidPathException: Illegal char <:> at index 74: journal.app-mergeDebugResources-31:/values/values.xml). Check logs for more details``

Here is build values.xml file 74 line

I think i know the reason behind this error

material library adds an attr as
<attr format="color|reference" name="dividerColor"/>

and there is a library added in this project name - "net.dankito.utils:android-utils"
in this library same attr is defined as
<attr format="reference" name="dividerColor"/>

so this need to be updated

If you think i am right then Please resolve this issue

Anyone found a solution to this?
I really need a solution, cannot update my app any more.
Is there anyone who is able to import projects 'net.dankito.richtexteditor:richtexteditor-android' and 'net.dankito.utils:android-utils' in android studio, so that one can create forks and change attribute's name "dividerColor"?

[kingYogi911]

I know a temporary sloution for this, just search for 'net.dankito.utils:android-utils' under "external libraries" in android studio, then
delete dividerColor in file Res->values->values.xml , the project will compile successfully.
