[WhatYouDoing]

Всем привет,столкнулся с такой проблемкой,не могу понять почему setImageResource,крашит приложение делаю так

ImageView simpleImageView = (ImageView) findViewById(R.id.ColMemberID);
simpleImageView.setImageResource(R.mipmap.ic_launcher);

А в консоле вот так

W/art: 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

Attempt to invoke virtual method 'void android.widget.ImageView.setImageResource(int)' on a null object reference

Что-то напутали с findViewById, видимо нет такого id в данной Activity, или он не ImageView, дело не в setImageResource, подобное будет и с любыми другими методами этого ImageView.
