Android APK - differences in Linux vs. Windows

I am using 2 build environments in parallel: Windows and Ubuntu.
When I build APK in Windows (via command line) - the APK is fine and runs great.
But when I build exactly the same project on Ubuntu - it fails (running on the same Android device).
I clone the project from the same git repository, and during the gradle build - I receive the one-to-one same messages.
Have no idea where I should start digging.
Any advise will be appreciated.
BTW, I have run-time logs from both APK's:
The logs:

why android emulator not working

When I updated the Android Studio a few days ago, the Android Emulator stopped working. I tried to open a blank activity and the emulator did not work as well.
All the SDK tools have been installed and updated. Below are the event log and Logcat of a blank activity (Hello World!) when I run the blank activity.

I went to the Settings->Advanced in the Extented Controls in the emulator and then to Advanced and changed the OpenGL ES Render to SwiftShader and the OpenGL ES API level to Compatibility (OpenGL ES 1.1/2.0) and the errors appear to have gone away and the screen is now not displaying a white screen and is instead is displaying the google map, which is what the program is supposed to do. Does this seem like a good solution? Is there more I should do to not get screwed up in the future?

Why I get all this error when initializing my AVD?

Actually, I'm interested in know if by correcting any of this errors I can improve the performance of the AVD, which is too slow.
I'm on Android Studio 1.3.2, with Android SDK 6 and Java SDK 8. On a Intel i3 with 4GB RAM (~1.5GB free).
AVD: Nexus_5_API_23_x86 with 512MB RAM.
The complete errors log from Logcat is here:
