Sorry, for my delay, I was trying some code to fix but I couldn't
I made a short app, copying some classes and I made an APK file similar to one that I have on the play store and install it on my phone, after that I made some changes to the code, to have a one similar to my update version and I install it again over the previous one and everything works OK! Now I'm more lost.
The imageView never have a null because I put an image in every object
thanks again for the help!
