BroadcastReceiver 启动 Activity 无法全屏

Question

RT：
   在广播里面启动一个Activity，该Activity无法全屏显示。正常启动该Activity是可以全屏的。求解答
代码如下：
/**
 * 注册广播
 */
private void registerIntentReceivers() { 
registerReceiver(new BroadcastReceiver() { 
public void onReceive(Context context, Intent intent) {
Intent intent1=new Intent(context, TrialControlActivity.class);
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent1);
}
} , new IntentFilter(Intent.ACTION_SCREEN_OFF)); 
}调试日志里面警告信息如下：IInputConnectionWrapper  showStatusIcon on inactive InputConnection
WindowManager  No window to dispatch pointer action 0

Answer 1

intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
这段去掉后看看
