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);
设置Global.AIRPLANE_MODE_ON失败,好像我检查它返回0(关闭)的状态一样
尝试广播其意图会引发以下异常：
