    <Default Constructors implemented> {
        setOrientation(LinearLayout.VERTICAL);
        inflate(context, R.layout.horizontal_progress, this);
    }

    @Override
    protected void onFinishInflate() {
        //Continue with rest of the logic.
    }

Last segment of the Stack-trace.

Caused by: android.view.InflateException: Binary XML file line #39: Error inflating class ProgressWidget at android.view.LayoutInflater.createView(LayoutInflater.java:620) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:696) at android.view.LayoutInflater.rInflate(LayoutInflater.java:755) at android.view.LayoutInflater.rInflate(LayoutInflater.java:758) at android.view.LayoutInflater.inflate(LayoutInflater.java:462) at android.view.LayoutInflater.inflate(LayoutInflater.java:397) at android.view.LayoutInflater.inflate(LayoutInflater.java:353) at android.view.View.inflate(View.java:1746

Everything works right on Phone Device - Samsung Galaxy S5 SM-G900A, Android Version 5.0. Always crashing with above stack-trace on Asus Nexus 7, Android 4.4.3.

This ProgressWidget is a custom reusable component of an Android Library module, that will be used with a Project Module. The main Project Module is expected to cater minSDKVersion 16 all the way up to TargetSDKVersion 24.

Any pointers as to what may be causing the crash only on Tablet device will be greatly appreciated.
