Throwing OutOfMemoryError "Could not allocate JNI Env"

[captain-miao]

compile 'com.github.captain-miao:recyclerviewutils:1.2.1-SNAPSHOT'

    @BindingAdapter({"compressImageUrl"})
    public static void loadImageCompress(ImageView imageView, String url) {
        //recycle bitmap
        Drawable drawable = imageView.getDrawable();
        if (drawable instanceof BitmapDrawable) {
            imageView.setImageDrawable(null);
            Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap();
            Log.d(TAG, "recycle bitmap, w:" + bitmap.getWidth() + ", h:" + bitmap.getHeight());
            bitmap.recycle();
        }
        Picasso.with(imageView.getContext().getApplicationContext())
                .load(url)
                .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE)
                .placeholder(R.drawable.ic_image_load_place_holder)
                .config(Bitmap.Config.RGB_565)
                .tag(PicassoOnScrollListener.TAG)
                .into(imageView);
}

fast scroll RecycleView, load image more and more and more...

Try use pauseTag() from this blog image-loading-with-picasso,it's working.

The solution: from Picasso Singleton Usage

if you use the builder you should create your own singleton to hold your instance of Picasso and clean it up when your done. Do not use builder every time that you use picasso because it creates a new instance. I believe that Picasso.with(context) just takes your context and calls getApplicationContext and stores a singleton instance of picasso with the application context.

use:

        Picasso.with(imageView.getContext().getApplicationContext())
                .load(url.replace("large", "bmiddle"))
                .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE)
                .placeholder(R.drawable.ic_image_load_place_holder)
                .config(Bitmap.Config.RGB_565)
                .tag(PicassoOnScrollListener.TAG)
                .into(imageView);

not:

Picasso.Builder builder = new Picasso.Builder(imageView.getContext().getApplicationContext());
