活动不从广播接收广播定制意向接收器

我有一个广播接收机（BackgroundReceiver），该监听去除包，然后广播包的名称到一个活动（AnalyzeActivity）活动不从广播接收广播定制意向接收器

BackgroundReceiver.java

public static final String REMOVED_INTENT = "com.analyze.project.RemovedReceiver"; 

    public void onReceive(Context context, Intent intent) { 
     String actionStr = intent.getAction(); 
     if (Intent.ACTION_PACKAGE_REMOVED.equals(actionStr)) { 
      Uri uri = intent.getData(); 
      String pkg = uri != null ? uri.getSchemeSpecificPart() : null; 
      Log.i("Logging Service", "Package Removed: " + pkg); 
      //Toast.makeText(context, "Package Removed:" + pkg, Toast.LENGTH_SHORT).show(); 

      Intent c = new Intent(); 
      c.setAction(REMOVED_INTENT); 
      c.putExtra("Package", pkg); 
      context.sendBroadcast(c); 
     } 
    }

我动态注册我的AnalyzeActivity内的接收器和监听定制广播意图BackgroundReceiver

AnalyzeActivity.java

@Override 
     protected void onResume() { 
      super.onResume(); 
      // Register Sync Recievers 
      IntentFilter intentToReceiveFilter = new IntentFilter(); 
      intentToReceiveFilter.addAction(BackgroundReceiver.REMOVED_INTENT); 
      this.registerReceiver(mIntentReceiver, intentToReceiveFilter, null, mHandler); 
      mReceiversRegistered = true; 

     } 

    final BroadcastReceiver mIntentReceiver = new BroadcastReceiver() { 
     @Override 
     public void onReceive(Context context, Intent intent) { 
      String Package = intent.getStringExtra("Package"); 
     if (intent.getAction().equals(BackgroundReceiver.REMOVED_INTENT)) { 
       Toast.makeText(context, "(A) Package Removed: " + Package, Toast.LENGTH_SHORT).show(); 
       Log.i("Package Removed", "(A) Package Removed: " + Package); 
      } 

     } 
    };

但我的活动似乎并不能够在所有接收广播意图。

第一BR是否工作？（BackgroundReceiver） –

我只是想在你的虚拟项目代码（在这里我提出从onOptionsItemSelected（）方法广播），它是工作的罚款。当您收到一个自定义的播放您能收到来自系统软件包删除广播... –

是您的活动（如广播注册）是可见的？ –

使用此功能在您的onResume

IntentFilter filter = new IntentFilter(BackgroundReceiver.REMOVED_INTENT); 

mIntentReceiver intentToReceiveFilter = new mIntentReceiver(); 

registerReceiver(intentToReceiveFilter,filter);

注册broacast并用它来从包装中取出广播接收器发送广播

Intent intent = new Intent(BackgroundReceiver.REMOVED_INTENT); 
intent.putExtra("Package", pkg); 
context.sendBroadcast(intent);

请让我知道，如果它解决您的问题
