Picasso Load Image Failed and App Crashing

Question

I\'m new to Android development, I\'m trying to load image from url using Picasso, but it failed when I navigate to the Picasso loading activity.

Below is the code t

Answer 1

From what I see, you spent a reference to the instance of the activity Context context = this; outside Oncreat method (), so be getting NullPointerException

Here

Picasso.with(context).load("http://postimg.org/image/wjidfl5pd/").into(ImageView1);

the context variable is null

Change this:

//Declaring Variable
ImageView ImageView1 = (ImageView)findViewById(R.id.forthImage);
Context context = this;

By:

//In onCreate()  

ImageView ImageView1 = (ImageView)findViewById(R.id.forthImage);  
Picasso.with(this).load("http://postimg.org/image/wjidfl5pd/").into(ImageView1);

Answer 2

final Target mTarget = new Target() {
        @Override
        public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom loadedFrom) {
            Log.d("DEBUG", "onBitmapLoaded");
            progress_bar.setVisibility(View.GONE);
            cropImageView.setImageBitmap(bitmap);
        }

        @Override
        public void onBitmapFailed(Drawable drawable) {
            Log.d("DEBUG", "onBitmapFailed");
        }

        @Override
        public void onPrepareLoad(Drawable drawable) {
            Log.d("DEBUG", "onPrepareLoad");
        }
    };
    Picasso.with(this).load(wallpaper.getMain_image()).into(mTarget);
    cropImageView.setTag(mTarget);

Note:cropImageView is ImageView
