Android LocalBroadcastManager不工作

我正在尝试将消息从服务发送到活动，但由于某些原因，它无法工作

活动

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_barcode);
   LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
                new IntentFilter("custom-event-name"));


private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // Get extra data included in the Intent
            Boolean state = intent.getBooleanExtra("state",false);
            if(state){
                Toast.makeText(getApplicationContext(),"Данные успешно отправлены",Toast.LENGTH_SHORT).show();
            }
        }
    };

    @Override
    protected void onDestroy() {
        // Unregister since the activity is about to be closed.
        LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
        super.onDestroy();
    }

服务

   private void sendMessage(boolean state) {
        Log.d("sender", "Broadcasting message");
        Intent intent = new Intent("custom-event-name");
        // You can also include some extra data.
        intent.putExtra("state", state);
        LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
    }

显示Log.d“广播消息”，然后什么也不发生

问题已解决

在android清单中

<service
    android:name=".service.TerminalService"
    android:process=":update_service" >
</service>

当指定android:process时，localbroadcastmanager似乎不工作。我刚刚删除了android:processline，它工作了

你的代码没有问题。只更新你的接收方法

else

子句

  private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                // Get extra data included in the Intent
                Boolean state = intent.getBooleanExtra("state",false);
                if(state){
                 Toast.makeText(getApplicationContext(),"Данные успешно отправлены",Toast.LENGTH_SHORT).show();
             }
             else {
                 Toast.makeText(getApplicationContext(),"else message ",Toast.LENGTH_SHORT).show();

             }
            }
        };

支持：localbroadcastmanager->change

androidx.localbroadcastmanager:localbroadcastmanager:1.0.0

您确定

state

为真吗？此外，尽可能使用本机类型，从

布尔状态

更改为

布尔状态

onReceive方法是否执行？intent.putExtra（“状态”，状态）；什么是状态变量值？onReceive未被调用这是一个问题，onReceive方法根本未被调用。问题解决了，它不起作用的原因是在清单中，过于简洁，无法理解。
