POmapping from asynctask to intent service
text
Body
copied!<p>I have an android app widget where I have used async task for my network calls. NOw I want to shift my calls from asynctask to intent service. doInBackground() 's work can be done in onHandleIntent() but what about onPreExecute() and onPostExecute(). I have the progress bar code in these 2 methods to give a spinning effect for my refresh button. Where should I put the code for this in intent service? </p> <p>UPDATE</p> <pre><code>public class StoreWidgetProvider extends AppWidgetProvider { @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { super.onUpdate(context, appWidgetManager, appWidgetIds); updateViews = new RemoteViews(context.getPackageName(), R.layout.widget_main_layout1); mContext = context; mProgressBar = new ProgressBar(context); Intent localIntent = new Intent(context,StoreWidgetService.class); context.startService(localIntent); // try { // fetchTask.execute().get(); // } catch (InterruptedException e) { // // TODO Auto-generated catch block // e.printStackTrace(); // } catch (ExecutionException e) { // // TODO Auto-generated catch block // e.printStackTrace(); // } MyCurrentLocation(mContext); imageLoader = new ImageLoader(mContext); updateViews.setOnClickPendingIntent(R.id.next, next_buildButtonPendingIntent(context)); updateViews.setOnClickPendingIntent(R.id.back, back_buildButtonPendingIntent(context)); updateViews.setOnClickPendingIntent(R.id.refresh, refresh_buildButtonPendingIntent(context)); //----These commented as they use context and this also gets null when killed---- //updateViews.setOnClickPendingIntent(R.id.outer_text_view, merchant_buildButtonPendingIntent(context)); //updateViews.setOnClickPendingIntent(R.id.check_in, checkin_buildButtonPendingIntent(context)); //updateViews.setOnClickPendingIntent(R.id.image_logo_id, pIcon_buildButtonPendingIntent(context)); pushWidgetUpdate(context,updateViews); } //my button listeners: next and prev //--not shown here--- public static void pushWidgetUpdate(Context context,RemoteViews views){ System.out.println("Inside pushwidget"); context = mContext; if(context!=null){ ComponentName myWidget=new ComponentName(context, StoreWidgetProvider.class); AppWidgetManager manager=AppWidgetManager.getInstance(context); manager.updateAppWidget(myWidget, views); } } } public static class StoreWidgetService extends IntentService implements ServerRequestEnvironment{ public StoreWidgetService() { super("StoreWidgetService"); // TODO Auto-generated constructor stub } // protected void onPreExecute(){ // // updateViews.setViewVisibility(R.id.refresh, View.GONE); // updateViews.setViewVisibility(R.id.progress, View.VISIBLE); // pushWidgetUpdate(mContext,updateViews); // } @Override public int onStartCommand(Intent intent, int flags, int startId){ super.onStartCommand(intent, flags, startId); return START_REDELIVER_INTENT; } @Override public void onHandleIntent(Intent intent) { //my data fetching done with all network calls } // protected void onPostExecute(Store storeObj) { // // updateViews.setViewVisibility(R.id.progress, View.GONE); // updateViews.setViewVisibility(R.id.refresh, View.VISIBLE); // // // pushWidgetUpdate(mContext,updateViews); // } @Override public IBinder onBind(Intent arg0) { // TODO Auto-generated method stub return null; } } } </code></pre>
