Picasso: into(Target target) but sometime only onPrepareLoad come .

[hackill]

public void into(Target target) {}

sometime only onPrepareLoad come, onBitmapLoaded not come & onBitmapFailed not come.

it may be the problem below

if (!data.hasImage()) {
picasso.cancelRequest(target);
target.onPrepareLoad(setPlaceholder ? getPlaceholderDrawable() : null);
return;

}

here is my source code

Picasso.with(context).load(avatarModel.getUrl())
.placeholder(R.drawable.user_img_default)
.error(R.drawable.user_img_default)
.into(new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
Log.i(TAG, "onBitmapLoaded: ");
saveUserAvatar(avatarModel);
if (callBack != null) {
callBack.onBitmapLoaded(bitmap, from);
}
}

                @Override
                public void onBitmapFailed(Drawable errorDrawable) {
                    Log.i(TAG, "onBitmapFailed: ");
                    saveUserAvatar(null);
                    if (callBack != null) {
                        callBack.onBitmapFailed(errorDrawable);
                    }
                }

                @Override
                public void onPrepareLoad(Drawable placeHolderDrawable) {
                    Log.i(TAG, "onPrepareLoad: ");
                    if (callBack != null) {
                        callBack.onPrepareLoad(placeHolderDrawable);
                    }
                }
            });

@JakeWharton I have been put forward this problem before。

[JakeWharton]

Do not call into by passing in new Target(). Store the Target instance somewhere that will not be garbage collected (implement on a view, in a view tag, on a view holder) and pass the reference to into.

@hackill what was your solution for this as

@Override public void onPrepareLoad(Drawable placeHolderDrawable) { //placeHolderDrawable is returning null }
