Question

I am using asy task for doing loading proccess while the service is supposed to take care about the connection.
I am getting some error on the line:

serviceIntent.putExtra("receiver",new DownloadReceiver(new Handler()));

when I am using AsyncTask and service to do the connection.
my code is for AsyncTask is:

 private class DownloadReceiver extends ResultReceiver{
public DownloadReceiver(Handler handler) {
    super(handler);
}

@Override
   protected void onReceiveResult(int resultCode, Bundle resultData) {
    super.onReceiveResult(resultCode, resultData);
  //  if (resultCode == DownloadService.UPDATE_PROGRESS) {
        int progress = resultData.getInt("progress");
     //   mProgressDialog.setProgress(progress);
     //   if (progress == 100) {
       //     mProgressDialog.dismiss();
        }
    }



  protected String doInBackground(String... params) {

    Intent serviceIntent = new Intent();
            serviceIntent.putExtra("url", "www.google.com");

            new DownloadReceiver(new Handler());
            serviceIntent.putExtra("receiver",new DownloadReceiver(new Handler()));
    serviceIntent.setAction("connection.DownloadService");
    context.startService(serviceIntent);

so what can be the problem?

Answer 1

if( this error == compile time error){
`DownloadReceiver` class should implements the   Parcelable interface 
}
else{

I think you are getting an error since you are creating the Handler object inside the doInBackground() method which executed in another thread than the UI one, then some where in your application you are accessing the UI Thread using that Handler object
. Note : To do that correctly you SHOULD create the Handler in UI Thread. what a good place to do that for your case .

onPostExecute

or put it as a instance variable . and pass it in the constructor;

}
