Question

is it possible to detect screen rotation? I mean – rotation only, which is clearly distinguishable from activity initialization from another activity?

The onXxx methods seem not to be useful for this, I have tried adding/removing a flag from the starting Intent (the removing seems not to be reflected, on rotate the flag is there), and have tried adding android:configChanges=”orientation” for the activity in the manifest, however the onConfigurationChanged method seems to be called every second rotation… wired.

I guess I am missing something… but haven’t found clear solution in the other related threads.

Any ideas?

Manifest:

<activity android:name=".MyActivity" android:configChanges="screenSize|orientation|screenLayout|navigation"/>

Activity:

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    Log.d("tag", "config changed");
    super.onConfigurationChanged(newConfig);

    int orientation = newConfig.orientation;
    if (orientation == Configuration.ORIENTATION_PORTRAIT)
        Log.d("tag", "Portrait");
    else if (orientation == Configuration.ORIENTATION_LANDSCAPE)
        Log.d("tag", "Landscape");
    else
        Log.w("tag", "other: " + orientation);

    ....
}
