I have created an application with android studio, never change a single word in any file. when trying to run it on the emulator I got the following error: W/EGL_emulation﹕ eglSurfaceAttrib not implemented W/OpenGLRenderer﹕ Failed to set EGL_SWAP_BEHAVIOR on surface 0xa6c1ace0,error=EGL_SUCCESS I/Choreographer﹕ Skipped 45 frames! The application may be doing too much work on its main thread. W/EGL
