Intenservice中有什么问题

Question

我已经成功使用了几次intenservice，但在当前的应用程序中，我无法让broadcastreceiver的onreceive（）开始。我在IntentsService和IntentFilter中有精确的字符串，在onresume与Broadcastreceiver一起注册。

    filter = new IntentFilter("com.currencyconverter2.intent.action.MESSAGE");
    Log.d("CC2", "intent filter created");
    filter.addCategory(Intent.CATEGORY_DEFAULT);
    Log.d("CC2", "filter category added");
    receiver = new MessageReceiver();
    Log.d("CC2", "receiver instantiated");
}

public void onResume(){
    super.onResume();
    registerReceiver(receiver, filter);
    Log.d("CC2", "receiver registered");
}

public void onPause(){
    super.onPause();
    unregisterReceiver(receiver);
    Log.d("CC2", "receiver unregistered");
}

public class MessageReceiver extends BroadcastReceiver{
    public void onReceive(Context context, Intent intent){
        Log.d(Tag, "entered onReceive...");
        String html = intent.getStringExtra("OUTPUT");
        webView.setBackgroundColor(Color.parseColor("#f4f36f"));
        webView.loadDataWithBaseURL(null, html, "text/html", "utf-8", null);
    }
}

.

我还在manifest.xml中指定了服务。

<service android:name=".IntentServiceTest"></service>

.

我的日志告诉我，IntentBroadcast是从IntenserVice播出的，并且该应用程序停止了。BroadcastReceiver似乎没有收到它。怎么了？谢谢！

编辑：

我的IntensiveService

        Intent broadcastIntent = new Intent();
        Log.d(Tag, "setting intent action");
        broadcastIntent.setAction("com.currencyconverter2.intent.action.MESSAGE");
        Log.d(Tag, "adding intent category");
        broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
        Log.d(Tag, "putting intent extra");
        broadcastIntent.putExtra("OUTPUT", data.text());
        Log.d(Tag, "sending broadcast");
        sendBroadcast(intent);

    }catch(Exception e){
        e.printStackTrace();
        //System.out.println("f");
    }
}

}

.

编辑2：

找到了错误。

                          Intent broadcastIntent = new Intent();
        Log.d(Tag, "setting intent action");
        broadcastIntent.setAction("com.currencyconverter2.intent.action.MESSAGE");
        Log.d(Tag, "adding intent category");
        broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
        Log.d(Tag, "putting intent extra");
        broadcastIntent.putExtra("OUTPUT", data.text());
        Log.d(Tag, "sending broadcast");
        sendBroadcast(intent);

.

我应该有sendbroadcast（广播节）;而是。

Answer 1

检查您的androidmanifest.xml：

<receiver android:name=".MessageReceiver">
<intent-filter>
<action android:name="com.currencyconverter2.intent.action.MESSAGE" />
<category android:name="android.intent.category.Default" />
</intent-filter>
</receiver>

.
