Android Development AIRPLANE_MODE_ON Query

Posted by JD 12/16/2011 at 04:00

On a Xoom Android Tablet, this code works


 protected static boolean isAirplaneModeOn(Context context)

{

    return 

Settings.System.getInt(context.getContentResolver(),

                Settings.System.AIRPLANE_MODE_ON, 0) != 0;

}


But on an Acer Icona A500, it does not. However, this


 protected static boolean isAirplaneModeOn(Context context)

{

    return 

Settings.System.getInt(context.getContentResolver(),

                Settings.System.AIRPLANE_MODE_ON, 0) == 1;

}


works on both devices. If you've read the Android SDK documentation, it is less than clear about the distinction. I've found example uses for the first code online, so I guess many programs may not properly recognize Airplane_Mode. As a C/C++ dev, we expect comparisons to be against 0 or non-zero, not some magic number, 1.
