I've made an application that was tested on three mobile phones. Two of them have android version 7 and application works on them without any errors. The third one has android version 6.01 and when I start application, it goes blank and on logcat there are 2 warnings:
ClassLoader referenced unknown path:
/data/app/com.ja.prog-1/lib/arm
Second one:
Before Android 4.1, method android.graphics.PorterDuffColorFilter android.support.graphics.drawable.VectorDrawableCompat.updateTintFilter
(android.graphics.PorterDuffColorFilter, android.content.res.ColorStateList, android.graphics.PorterDuff$Mode) would have incorrectly overridden the package-private method in android.graphics.drawable.Drawable
