Question

public static class TestTask extends AsyncTask<Void, Integer, Integer> {

    private String stacktrace;

    public TestTask (String stacktrace){

        this.stacktrace = stacktrace;
    }

    @Override
    protected Integer doInBackground(Void... params) {

        try {
            Log.i("async", "doInBackground 1"); //this gets logged
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost("http://xx.xx:8080/android/service.php");
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("action", "logexception"));
            nameValuePairs.add(new BasicNameValuePair("stacktrace", stacktrace));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            HttpResponse response = httpclient.execute(httppost);
            Log.i("async", "doInBackground 2"); //this gets logged
            return 1;

        } catch (Exception e) {
            e.printStackTrace();
            return 0;
        }

    }

    protected void onPreExecute(){
        Log.i("async", "onPreExecute"); //this gets logged
    }

    @Override
    protected void onPostExecute(Integer result) {
        Log.i("async", "onPostExecute"); //this doenst get logged!


    }
}

I’ve been checking out the other SO threads regarding this, but according to them, my code looks correct as far as i can tell. So why do i never reach Log.i("async", "onPostExecute");? Thanks

Answer 1

Did you create your AsyncTask on UI Thread?
Others seems good. Generics and annotations are fine.

So probably problem is that your doInBackground method never returns because onPostExecute is automatic called when doInBackground something will return.
