thanks for your answering. i'm trying to build an moodle apk in android studio that i've cloned the 3.5 version from git. when i try to generate the apk, i get such a compiling error:
error: package android.support.v4.app does not exist
but i've added that library as you can see in this picture
because of that i've tryed the 3.4 version and it was built successfully
what is the problem with 3.5?
