UPDATE: Valery's answer works!
Obsolete answer:
That's not the perfect fix, it's just temporary until I have time to take a deep look into the problem.
Downgrade your gradle plugin:
- File -> Project Structure
- Click at "Project"
- At "Gradle version" field put:
- At "Android Plugin Version" field put:
- Hit "OK"
Accept the messages, sync the project, etc... Android Studio may prompt a windown asking for update gradle plugin again, just don't accept it for now...
I guess the update on gradle changed the way the builds are made, maybe something on Android.mk will have to change or some other parameter on build.grade...
edit: I found some clue at: https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html
API changes
Android plugin 3.0.0 introduces API changes that removes
certain functionalities and may break your existing builds. Later
versions of the plugin may introduce new public APIs that replace
broken functionalities.
Modifying variant outputs at build time may not work Using the Variant
API to manipulate variant outputs is broken with the new plugin. It
still works for simple tasks, such as changing the APK name during
build time, as shown below:...
So, I guess we should keep using the temporary fix (not updated version of gradle)...
