How can one detect airplane mode on Android?

Question

I have code in my application that detects if Wi-Fi is actively connected. That code triggers a RuntimeException if airplane mode is enabled. I would like to display a separate error message when in this mode anyway. How can I reliably detect if an Android device is in airplane mode?

Answer 1

/** * Gets the state of Airplane Mode. *  * @param context * @return true if enabled. */ private static boolean isAirplaneModeOn(Context context) {     return Settings.System.getInt(context.getContentResolver(),            Settings.Global.AIRPLANE_MODE_ON, 0) != 0;  } 

Answer 2

By extending Alex's answer to include SDK version checking we have:

/**  * Gets the state of Airplane Mode.  *   * @param context  * @return true if enabled.  */ @SuppressWarnings("deprecation") @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1) public static boolean isAirplaneModeOn(Context context) {             if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {         return Settings.System.getInt(context.getContentResolver(),                  Settings.System.AIRPLANE_MODE_ON, 0) != 0;               } else {         return Settings.Global.getInt(context.getContentResolver(),                  Settings.Global.AIRPLANE_MODE_ON, 0) != 0;     }        }
