我正在尝试以编程方式设置飞行模式。
Settings.System.putInt(context.getContentResolver(), Settings.Global.AIRPLANE_MODE_ON, 1);
Intent aeroPlaneIntent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
aeroPlaneIntent.putExtra("state", true);
context.sendBroadcast(aeroPlaneIntent);
当我尝试设置Global.AIRPLANE_MODE_ON时,操作失败,并且如果我检查状态,则返回0(OFF)。
尝试广播意图会引发以下异常:

有没有一种方法可以设置飞行模式开/关?请帮忙。
