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.

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

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

I have tried as mentioned in link. But I have this problem http://stackoverflow.com/questions/34474603/android-images-are-not-getting-downloaded-very-slow — Masthan Vali Syed, Dec 26 '15 at 19:45

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

refer here :- java download multiple files using threads
