Question

我正在创建我的第一个intent service，我已经按照this教程但由于某种原因我的意图服务永远不会启动。我试图从片段中调用intentService。这是片段的onCreate代码：

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    {
        .....

        IntentFilter filter = new IntentFilter(ResponseReceiver.ACTION_RESP);
        filter.addCategory(Intent.CATEGORY_DEFAULT);
        receiver = new ResponseReceiver();
        getActivity().registerReceiver(receiver, filter);

        return homeSalePage;
    }

现在从intentService函数的某些AsyncTask调用onPostExecute的开始，这里是代码：

        Intent msgIntent = new Intent(getActivity(), SaleServiceForImages.class);
        Bundle b = new Bundle();
        b.putString("saleId", "H7m2F4zdT6");
        b.putInt("rowId", 1);
        msgIntent.putExtras(b);
        getActivity().startService(msgIntent);

SaleServiceForImages

    public class SaleServiceForImages extends IntentService 
    {
        public SaleServiceForImages() 
        {
            super("SaleServiceForImages");
        }

        @Override
        protected void onHandleIntent(Intent intent) 
        {
            Intent broadcastIntent = new Intent();
            broadcastIntent.setAction(ResponseReceiver.ACTION_RESP);
            broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
            ImgService imgService = new ImgService();
            Bundle b = intent.getExtras();
            Bitmap bitmap = imgService.getImageOfSale(b.getString("saleId"));
            broadcastIntent.putExtra("BitmapImage", bitmap);
            broadcastIntent.putExtras(b);
            sendBroadcast(broadcastIntent);
        }
    }

        <service android:enabled="true"  
         android:name="com.shale.services.SaleServiceForImages" />
    </application>

</manifest>

不知道从哪里开始查看，在调试时我注意到intentService构造函数从未被调用过。

Answer 1

我的证词错了，应该是：

<service 
         android:enabled="true"  
         android:name="com.shale.services.SaleServiceForImages" 
/>

意图服务从未开始
