Suspending all threads took Time in AsynTask in android

Question

I am trying to get images (15 images) from server in Android using below code.

Invoke AsynTask using below code:

DownloadImageSequencially lmib = new DownloadImageSequencially (); Lmib.execute (SplitImages);

Here SplitImages is array of image URLs.

 class DownloadImageSequencially extends AsyncTask<Object,Void,Void> { @Override protected Void doInBackground(Object... param) { // TODO Auto-generated method stub for (int indx = 0; indx < SplitImages.length; indx++) { downloadBitmap(SplitImages[indx],indx); } return null; } @Override protected void onPostExecute(Void result) { Log.i("Async-Example", "onPostExecute Called"); progressDialog.dismiss(); defailtReviewCardInitialisation(); reviewCardActions(); } private void downloadBitmap(String url,int indx) { // initilize the default HTTP client object HttpClient client = new DefaultHttpClient(); //forming a HttoGet request url = url.replace("\\\\",""); url = url.replace("\\"",""); Log.e("url","url: "+url); final HttpGet getRequest = new HttpGet(url); Log.e("Masthan1","Masthan1"); //HttpPost getRequest = new HttpPost(url); try { if (android.os.Build.VERSION.SDK_INT > 9) { StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); } Log.e("Masthan2","Masthan2"); HttpResponse response = client.execute(getRequest); Log.e("Masthan3","Masthan3"); //check 200 OK for success final int statusCode = response.getStatusLine().getStatusCode(); Log.e("Masthan4","Masthan4"); if (statusCode != HttpStatus.SC_OK) { Log.w("ImageDownloader", "Error " + statusCode + " while retrieving bitmap from " + url); } final HttpEntity entity = response.getEntity(); Log.e("Masthan5","Masthan5"); if (entity != null) { InputStream inputStream = null; try { // getting contents from the stream inputStream = entity.getContent(); Log.e("Masthan6","Masthan6"); // decoding stream data back into image Bitmap that android understands bitmapArray[indx] = BitmapFactory.decodeStream(inputStream); Log.e("Masthan7","Masthan7"); } finally { Log.e("Masthan8","Masthan8"); if (inputStream != null) { Log.e("Masthan9","Masthan9"); inputStream.close(); Log.e("Masthan10", "Masthan10"); } entity.consumeContent(); Log.e("Masthan11", "Masthan11"); } } } catch (Exception e) { // You Could provide a more explicit error message for IOException getRequest.abort(); Log.e("ImageDownloader", "Something went wrong while" + " retrieving bitmap from " + url + e.toString()); } } } 

This is the logcat of Android.

What I have observed is when we try to perform following actions in AsynTask it takes lot of time (at least 30 sec) even though I work at high speed internet or localhost.

1. Client.execute(getRequest);
2. Entity.getContent();

Please help me why is it taking time? You can also suggest me alternative methods if it performs good.

Answer 1

you are using single asynctask thread to download multiple files.. so obviously it will take more time if the files count is high .. if you want to download multiple files simultaneously then try to use

http://download.oracle.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html
