片段中的广播接收器无法从服务接收意图 [英] Broadcast Receiver in fragment not receive intent from service

问题描述

我有一个片段和一个服务，如下所示:

I have a fragment and a service as below:

我在Fragment.java文件中注册和注销LocalbroadcastManager

I register and unregister LocalbroadcastManager in file Fragment.java

@Override
public void onStart() {
   // TODO Auto-generated method stub
   super.onStart();
   IntentFilter intentFilter = new IntentFilter();
   intentFilter.addAction(ffmpegService.PROGRESS);
   intentFilter.addAction(ffmpegService.DONE);
   LocalBroadcastManager.getInstance(getActivity()).
       registerReceiver(receiver, intentFilter);
}

@Override
public void onStop() {
   LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(receiver); 
   super.onStop();
}

private final BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
   if(intent.getAction().equalsIgnoreCase(ffmpegService.PROGRESS)){
     ....
   }
}

在ffmpegService类中，我将广播发送到片段的1个处理程序中，如下所示:

In ffmpegService class, I send broadcast to fragment in 1 handler as below:

private Handler handler;
private Context mContext;

public void onCreate() {
   mContext = this.getApplicationContext();
}

@Override
public void onStart(Intent intent, int startid) {
   handler = new Handler();
   handler.postDelayed(workTask, 3000);
}

private Runnable workTask = new Runnable() {
   @Override
   public void run() {
     Intent intent = new Intent(PROGRESS);
     intent.putExtra("progress", 90);
     LocalBroadcastManager.getInstance(mContext).sendBroadcast(intent);
   }
}

但是在运行中，该片段没有从服务广播中接收任何信息.

But in running, the fragment did not receive anything from service broadcasting.

任何帮助将不胜感激！

谢谢.

推荐答案

我找到了根本原因.因为我的服务在自己的进程中运行.

I found the root cause. Because my service is running in own process.

<service
        android:name="com.media.ffmpeg.ffmpegService"
        android:enabled="true"
        android:process="com.media.ffmpegservice">
</service>

我删除了android:process ="com.media.ffmpegservice"并且运行正常.

I deleted android:process="com.media.ffmpegservice" and it works ok.
