Q:

java.lang.NoClassDefFoundError: com.squareup.picasso.Picasso

I try to use Picasso for the first time
like in the official site example:
private void setItemBgImageUsingPicasso(View convertView) {
    String imageUrl = getImageUrlFromOffer(convertView);

    ImageView offerImage = ((ImageView) convertView
            .findViewById(R.id.offerImage));
    Picasso.with(mOffersListActivity).load(imageUrl).into(offerImage);
}

but I get this error:
08-09 17:37:43.309: E/AndroidRuntime(17821): java.lang.NoClassDefFoundError: com.squareup.picasso.Picasso
08-09 17:37:43.309: E/AndroidRuntime(17821):    at com.zoomer.general.ImageAdapter.setItemBgImageUsingPicasso(ImageAdapter.java:384)

A:

You should put it in libs folder and Eclipse will pack it properly for you.
Or you leave it as it is, but go to project properties, Export tab and check the library. This way Eclipse will pack it in the final APK.
