How to set the AIRPLANE_MODE_ON to "True" or ON?

I a开发者_运维百科m planning to drop a call and I find this as one of workaround for that. How do I activate the airplane mode via code?

This way I will drop the call based on some event.

See the blog article Android: Controlling Airplane Mode ,

Works only upto API 16

// Toggle airplane mode.
Settings.System.putInt(
      context.getContentResolver(),
      Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1);

// Post an intent to reload.
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", !isEnabled);
sendBroadcast(intent);

where isEnabled is whether airplane mode is enabled or not.

Please keep in mind that this is no longer possible starting from Android 4.2 and above.

  public static boolean getAirplaneMode(Context context) {
      try {
      int airplaneModeSetting = Settings.System.getInt(context.getContentResolver(), Settings.System.AIRPLANE_MODE_ON);
      return airplaneModeSetting==1?true:false;
    } catch (SettingNotFoundException e) {
      return false;
    }
  }

You can do this:

        int mode = isEnable ? 1 : 0;
        Runtime.getRuntime().exec("settings put global airplane_mode_on "+mode);
        SystemClock.sleep(2000);
        Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
        intent.putExtra("state", isEnable);
        this.sendBroadcast(intent);

shell uid can change airplane_mode_on ,but send ACTION_AIRPLANE_MODE_CHANGED need permission (need to be system uid)

<uses-permission android:name="android.permission.WRITE_SETTINGS" />
