Android Question Intel cpu & Android 4.4.2 error

Hi to all,
My app is live on Google Play since 2014 without compatibilities problems.
This week a user notified me about an error on his Asus Memo Pad 7 with Intel processor inside.

The error:
java.lang.ClassCastException: android.view.View cannot be cast to android.widget.TextView

Java line:
mostCurrent._tabmanager.setTabTextSize((android.widget.TabHost (mostCurrent._tabordernew.getObject()),(float) (20));

Is it a know issue?

Thanks in advance!
