Qt5.7 Android stopped working after A. Studio updates
-
I just updated Android Studio and a bunch of SDK packages. Now when I build and run an application with QtCreator, in startup it gives only a blank (white, using default Controls2 style) screen. I reconfigured the project and even re-installed Android Studio from scratch. Here are some error lines from Application Output:
W/System.err( 2943): java.lang.ClassNotFoundException: android.graphics.drawable.RippleDrawable
W/System.err( 2943): Caused by: java.lang.ClassNotFoundException: android.graphics.drawable.RippleDrawable

W/EGL_emulation( 2943): eglSurfaceAttrib not implementedD/OpenGLRenderer( 2943): Enabling debug mode 0
The program initializes normally, gives c++ and qml debuggin output.
Then...
W/EGL_emulation( 2943): eglSurfaceAttrib not implemented

What could have gone wrong? Android build tools broken?
-
@Eeli-K it's like some misconfiguration with OpenGl, in this new A.Studio version, is there anything that possibly have disabled OpenGl or at least misconfigured it?
-
@Julian-Guarin Hardly so, like I said, I re-installed Android Studio and SDK from scratch and reconfigured QtCreator project. I can't be sure about the Android Studio, but I explicitely uninstalled it and deleted all the folders I knew of: the Studio installation, SDK installation, folders from user home folder, AppData. I don't know what still could have left something which could affect OpenGL or anything else. I hope A. Studio doesn't touch windows registry...

Emulator doesn't work but at least one real device works.

Good news. If I start the emulator from command line (see https://developer.android.com/studio/run/emulator-commandline.html) and use "-gpu swiftshader" option (see "emulator.exe -help"), it works. The GPU setting set through GUI didn't seem to work.
