selectQType a simple spinner. The values are getting populated from the DB and they are fine. 

     ArrayAdapter<String> spinnerArrayAdapter1 = 
            new ArrayAdapter<String>(SpotlighterBasicActivity.this,
                    android.R.layout.simple_spinner_item, spinnerQTypeList);
     spinnerArrayAdapter1.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item); 
     Spinner selectQType=(Spinner) findViewById(R.id.spinnerInputQType);

     selectQType.setPrompt("QType");// logcat points warning on this line.
     selectQType.setAdapter(spinnerArrayAdapter1);
     selectQType.setSelection(QTypeIndex);
     selectQType.setOnItemSelectedListener(new OnItemSelectedListener() {
     ...
     }

This is the output i get for Tablet:

Output on tablet

Strange part is that it is working perfectly fine for mobile category of emulators and devices, but giving warning for tablet category of emulators and devices.

Following is the logcat detail:
