Android Picasso not loading img to view from handler

Question

I trying to get pic url in Thread and load in Picasso, but image not shows. Url is valid. Picasso not load placeholder and error img. Without Thread and Handler works fine.

     final String[] sss = {""};
    final Handler hh = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            Picasso.with(context).load(sss[0]).resize(500, 281).centerCrop().into(mainHolder.ivPreview);
        }
    };
    Thread th = new Thread(new Runnable() {
        @Override
        public void run() {
            sss[0] = getUrl();
            hh.sendEmptyMessage(0);

        }
    });
    th.start();

You Check again getUrl() and context. This code work for me.

 public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final ImageView imageView= (ImageView) findViewById(R.id.imageView);

        final Context context=this;
        final String[] sss = {""};
        final Handler hh = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                super.handleMessage(msg);
                Picasso.with(context).load(sss[0]).resize(500, 281).centerCrop().into(imageView);
            }
        };
        Thread th = new Thread(new Runnable() {
            @Override
            public void run() {
                sss[0] = "http://teleflora.edgesuite.net/images/products/HW0_706075.jpg";
                hh.sendEmptyMessage(0);

            }
        });
        th.start();
    }
}
