Did I make a mistake? It's not working.
public void airplane() {
boolean isEnabled = Settings.System.getInt(this.getApplicationContext().getContentResolver(), Settings.System.AIRPLANE_MODE_ON, 0) == 1;
Settings.System.putInt(context.getContentResolver(),Settings.System.AIRPLANE_MODE_ON,isEnabled ? 0 : 1);
//Settings.System.putInt(this.getApplicationContext().getContentResolver(),Settings.System.AIRPLANE_MODE_ON,isEnabled ? 0 : 1);
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
}
This answer contains code necessary to do this. Also make sure you have the WRITE_SETTINGS
permission.
Adapted from Controlling Airplane Mode:
// read the airplane mode setting
boolean isEnabled = Settings.System.getInt(
getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, 0) == 1;
// toggle airplane mode
Settings.System.putInt(
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);
