Problem with download image

I tried to download image using this code.

FileMetaData myMetaData = new FileMetaData("518fb003a6b1878c340040c8");

FileOutputStream myOutputStream = null;

try {

myOutputStream = new FileOutputStream(new File(Environment.getExternalStorageDirectory(),"QWERTYUI"));

} catch (FileNotFoundException e) { }

client.file().download(myMetaData, myOutputStream, new DownloaderProgressListener()



public void onSuccess(Void arg0) {

Toast.makeText(getApplicationContext(), "DOWNLOAD_FIMISHED", Toast.LENGTH_SHORT).show();



public void onFailure(Throwable arg0) {

Toast.makeText(getApplicationContext(), arg0.getLocalizedMessage(), Toast.LENGTH_SHORT).show();



public void progressChanged(MediaHttpDownloader arg0) throws IOException {

Toast.makeText(getApplicationContext(), "SOMETHING_CHANGED", Toast.LENGTH_SHORT).show();




When I use this code, event onFailure executes every time with message: "Can't create handler inside thread that has not called Looper.prepare()"

What's the problem? Thanks.

The library uses Android's `AsyncTask` class to make network requests. These requests must be made on the main thread, or you will see that above error message.

If you need to call these methods from a different background thread (or another `AsyncTask`), you can call:


in your thread before using the library. Take a look here for more information:
