findPreference null on specific tablet

Question

On my google play error reporting page, there are error regarding NPE and it's only on tablets such as ASUS Transformer Pad TF300T and other Tablet S.

findPreference("setting").setOnPreferenceClickListener(

Is there anyway to make findPreference works on tablet?

Answer 1

I found the root of problem. Seems like tablet above 3.0 you have to put findPreference into each Fragment, not on the preferenceActivity. otherwise they crashed.
