android - 为什么 BroadcastReceiver 在 Android 条件下不进入 else

Question

我正在尝试从服务向 Activity 发送动态广播。当我从 Notification.class Service 发送 Broadcast 时，Activity 会收到该 Broadcast。但是当我尝试从 sendData.class 服务发送广播时， Activity 没有收到该数据。我不知道发生了什么事。这是我的 Activity 代码:-

        protected void onCreate(Bundle savedInstanceState) {
            .
            .
            .
            mIntentFilter = new IntentFilter();

            mIntentFilter.addAction(mBroadcastStringAction);

           .
           .
           .
           .
           .


        }


        private BroadcastReceiver mReceiver = new BroadcastReceiver() {
            @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
            @Override
            public void onReceive(Context context, Intent intent) {
// This Broadcast is called by getData.class service and not working :(
                if(intent.getAction().equals(PLAY_MUSIC)){

                    Toast.makeText(context, "Broadcast Recieved", Toast.LENGTH_SHORT).show(); //Not showing Toast message also
                    String action = intent.getStringExtra("play");
                    if(action.equals("true")) {
                        playBtnClick();
                    }
                }

//This Broadcast is Called by Notification.class & Working Properly
                if (intent.getAction().equals(mBroadcastStringAction)) {
                    int position = intent.getIntExtra("position", 0);
                    int duration = intent.getIntExtra("duration", 0);
                    sb.setMax(duration);
                    sb.setProgress(position);
                    setSongDetails();

                }
            } //I have also try else if condition also
        };

        @Override
        protected void onResume() {
            super.onResume();

            registerReceiver(mReceiver, mIntentFilter);

        }

        @Override
        protected void onPause() {

            super.onPause();

        }

        @Override
        protected void onDestroy() {

            super.onDestroy();
        }



    }

这是我发送广播的Notification.class

 Intent broadcastIntent = new Intent();
                broadcastIntent.setAction(MainPlayer.mBroadcastStringAction);
                broadcastIntent.putExtra("duration", mediaPlayer.getDuration());
                broadcastIntent.putExtra("position", mediaPlayer.getCurrentPosition());
                sendBroadcast(broadcastIntent);

这是我的 getData.class

 try {
                    Intent intent = new Intent(MainPlayer.PLAY_MUSIC);
                    intent.putExtra("play","true");
                    sendBroadcast(intent);
                    Log.d("EasysPlay","BroadCast Send");
                }catch(Exception e){
                    Log.d("EasysPlay",e.toString());
                }

我试过很多次了。但它不起作用。

Answer 1

将MUSIC_PLAYER 添加到下面onCreate 中的intent 过滤器

mIntentFilter = new IntentFilter();
mIntentFilter.addAction(mBroadcastStringAction);
mIntentFilter.addAction(MUSIC_PLAYER);
