I have two problems :(
First thing you have to know; When i run my app on the api 27 or 28, I don't have problem.
but when I try this (running) on api 23 (android 6.0) my build is crashing. And I take a error like this 'Unfortunately, Package installer has stopped'
After that, I realize that My imageViews doesn't seem in the Desing mode when Api 23 selected.
What's the problem with Api 23? I wanna build for android 6.0 to, what I have to do?
Solved
I copy my picture to mipmap folder problem solved!
