Android-Orientation-Test

An android orientation problem.

GOAL: Disable landscape mode only on Android smartphones

Clone this project, build and run. Turn your device (simulated or physical smartphone) into landscape mode and then open a new activity. You will notice that orientation will turn automatically into landscape mode (even though landscape it's disabled on smartphones thanks to portrait_only property contained in bool.xml) and, after a while, It will come back into portrait mode.

Additional notes

android:screenOrientation

This property cannot be used in order to preserve portrait or landscape orientation on tablets.
