从IntentService发送广播时，不调用onReceive（）的BroadcastReceiver方法

Question

正如标题所说，我有一个启动IntentService的Activity。在IntentService完成所有工作之后，我希望它将结果广播回我的Activity。但是，当我这样做时，我的BroadcastReceiver的onReceive方法不会被调用。我正在尝试从Android文档中遵循本指南：Report Status From an IntentService

这就是所有设置的方式：

我有一个类StatusReceiver，它扩展了BroadcastReceiver：

    class StatusReceiver extends BroadcastReceiver{

Context mContext;

public StatusReceiver(Context context) {
    mContext = context;
}

@Override
public void onReceive(Context context, Intent intent) {
    boolean success;

    success = intent.getBooleanExtra("success", false);

    if(success)
        Toast.makeText(mContext, "Profile picture updated.", Toast.LENGTH_SHORT).show();
    else
        Toast.makeText(mContext, "Profile picture couldn't be updated.", Toast.LENGTH_SHORT).show();
}

}

在我的Activity的onCreate（）中，我实例化一个StatusReceiver：

    //This broadcast receiver will receive the result of image uploads.
    statusReceiver = new StatusReceiver(getApplicationContext());

在我的onResume中，我注册了接收器：

    @Override
protected void onResume() {
    super.onResume();
    //register the receiver
    LocalBroadcastManager.getInstance(UserProfileSettings.this).registerReceiver(statusReceiver, new IntentFilter("result"));
}

在我的onPause（）中，我取消注册接收器：

    @Override
protected void onPause() {
    super.onPause();
    //unregister receiver when activity is paused
    LocalBroadcastManager.getInstance(UserProfileSettings.this).unregisterReceiver(statusReceiver);
} 

最后，在完成所有工作后，在我的IntentService中，我想将结果发送回Activity。从Firebase CompletionListener中调用此方法：

    /**
 * This method broadcasts the result of writing the user's new profile picture to Firebase.
 * @param success - boolean representing whether or not the write was successful.
 */
private void sendResult(final boolean success){

    Intent result = new Intent("result");
    result.putExtra("success", success);
    LocalBroadcastManager.getInstance(this).sendBroadcast(result);

}

听众：

    mDatabase.getReference(Users.NODE_NAME).child(userId).child("avatar").setValue(imageUrl, new DatabaseReference.CompletionListener() {
            @Override
            public void onComplete(DatabaseError databaseError, DatabaseReference databaseReference) {
                //if we didn't encounter an error
                if(databaseError == null)
                    sendResult(true);
                else
                    sendResult(false);
            }
        });
