Picasso java.lang.IllegalStateException: Method call should not happen from the main thread

Question

I am attempting to use Picasso to get three Bitmap images from a URL

public void onCreate(Bundle savedInstanceState) { 
  super.onCreate(savedInstanceState);
  setContentView(R.layout.tab2);
  Drawable d1 = new BitmapDrawable(Picasso.with(Tab2.this).load(zestimateImg1).get());
}

I am getting FATAL EXCEPTION with this code. I suspect it has to do with the fact that this should be done within AsyncTask, but I can't get it to work. If using that is avoidable, I would like to do this without using AsyncTask.

How can I get this code to run without crashing?

If the best way to do this is with AsyncTask, then that solution is ok.

Look again at the documentation of picasso and see where they call `get()` and how it's intended to be used. — zapl, Nov 28 '14 at 01:33
@zapl I find this: `android.graphics.Bitmap get() Synchronously fulfill this request.` I don't understand threads so much :/ — Brian, Nov 28 '14 at 01:37
I will also accept the `AsyncTask` solution, though i must load three images. I just need this to work lol — Brian, Nov 28 '14 at 01:52
@Brian Vanover Can you please provide your solution, actuallly i am working on the same problem. — harshita, Jul 06 '18 at 10:01
I was looking for a way to do it outside the main thread and the snippet in the question helped me. What an irony. — Bertram Gilfoyle, Oct 12 '18 at 14:39

None of above worked for me instead this

Handler uiHandler = new Handler(Looper.getMainLooper());
    uiHandler.post(new Runnable(){
        @Override
        public void run() {
            Picasso.with(Context)
                    .load(imageUrl)
                    .into(imageView);
        }
    });

Hope it may be useful for someone

You cannot make synchronous requests in the main thread. If you dont want to use an AsyncThread then just use Picasso together with a Target.

Picasso.with(Tab2.this).load(zestimateImg1).into(new Target(...);

I recommend you save a reference to your target like so:

Target mTarget =new Target (...);

This is because Picasso uses weak references to them and they might be garbage collected before the process is finished.

Can you expand on this with an example? – Brian Nov 28 '14 at 01:46

There's no `with` in the newer version of Picasso – Ravinder Payal May 14 '18 at 08:13

Just for the record:

Picasso.with(context).load(url).into(new Target() {
    @Override
    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
        Log.i(TAG, "The image was obtained correctly");
    }

    @Override
    public void onBitmapFailed(Drawable errorDrawable) {
        Log.e(TAG, "The image was not obtained");
    }

    @Override
    public void onPrepareLoad(Drawable placeHolderDrawable) {
        Log.(TAG, "Getting ready to get the image");
        //Here you should place a loading gif in the ImageView
        //while image is being obtained.
    }
});

Source: http://square.github.io/picasso/

onPrepareLoad() is called always after starting the request. from can be "DISK", "MEMORY" or "NETWORK" to indicate where was the image obtained from.

try this:

Handler uiHandler = new Handler(Looper.getMainLooper());
uiHandler.post(new Runnable(){
    @Override
    public void run() {
        Picasso.with(Context)
                .load(imageUrl)
                .into(imageView);
    }
});

This is the same answer of Juan José Melero Gómez but with kotlin:

val imageBitmap = Picasso.get().load(post.path_image).into(object: Target {
        override fun onPrepareLoad(placeHolderDrawable: Drawable?) {
            Log.(TAG, "Getting ready to get the image");
             //Here you should place a loading gif in the ImageView
             //while image is being obtained.
        }

        override fun onBitmapFailed(e: Exception?, errorDrawable: Drawable?) {
            Log.e(TAG, "The image was not obtained");
        }

        override fun onBitmapLoaded(bitmap: Bitmap?, from: Picasso.LoadedFrom?) {
            Log.i(TAG, "The image was obtained correctly");
        }

    })
