问题
I am getting eglCreateWindowSurface GL Error EGL_BAD_ALLOC when open app first time after installing in Samsung Galaxy S6 and same code working fine in other device.
I tried to clean memory and destroy texture and deinitialize all opengl object on destroy but that cant help me.

回答1:
I solved the OpenGL error EGL_BAD_ALLOC
This error occurs due to I am not handling renderer properly with activity life cycle.

Workaround-to-losing-the-opengl-context-when-android-pauses
So your Activity's onPause() should look like this:
@Override
public void onPause() {
eglSurface.setVisibility(View.GONE);
super.onPause();
...
}
And you restore your GLSurfaceView to the hierarchy not from onResume() but from onWindowFocusChanged() :
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus && eglSurface.getVisibility() == View.GONE) {
eglSurface.setVisibility(View.VISIBLE);
}
...
}
