I have beeen following this tutorial: Click Me

The problem is that I have my images in byte[] in my database, I don't have the links for each image. The tutorial works great. But i don't know my url image because I use byte[] to store the data, so: How can I convert the urls to byte[] using asynchronous?

I don't put my code because is the same like the tutorial! But if your like, let me know

Thanks for helping me!

The tutorial loads image from the String urls. Since you do not have image URLs and you are saving images in your database as byte[] so you need to render images from byte[]. So, instead of loading images from URL, you can load byte[] to create a Bitmap. This is the code that can convert byte[] to bitmap. 

ByteArrayOutputStream baoStream = new ByteArrayOutputStream();
bmpOld.compress(Bitmap.CompressFormat.PNG, 100, baoStream);
bytesImage = baoStream.toByteArray();
bmpNew = BitmapFactory.decodeByteArray(bytesImage, 0, bytesImage.length);

This code is taken from Android byte array to Bitmap How to

And yes, definitely, you will have to modify implementation of MemoryCache and and ImageLoader accordingly as well.
