java.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams android 4.1.2

Question

I have this Exception only on some devices on android 4.1.2. So, I want to know what is the problem it can be. Here is stack trace - no one line from my code, only from SDK - exception happens in SDK, so no lines were missed:

change import android.widget.LinearLayout.LayoutParams; to import android.widget.ViewGroup.LayoutParams; — Shayan Pourvatan

It seems that the params you dynamically set for the view does not match the params type the parent expects — TacB0sS

Your import statement for LayoutParams might be importing ViewGroup.LayoutParams or vice versa ...Please check it once — Toppers

In your code you are importing import android.widget.LinearLayout.LayoutParams instead of android.view.ViewGroup.LayoutParams;

so Delete import android.widget.LinearLayout.LayoutParams;

and Add import android.view.ViewGroup.LayoutParams;

I think you are right, I tried to change my code in this way, but can not check because of I don't have device on android 4.1.2. So, I just accept your answer.
