actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS) produce NullPointerException

Question

import android.app.ActionBar;
import android.app.FragmentTransaction;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.FragmentActi         


        

Answer 1

The real problem is in res/values/style.xml and res/values-v14/style.xml in the AppBaseTheme (in two styles).
If change Theme.AppCompat.Light and Theme.AppCompat.Light.DarkActionBar by Theme.Holo.Light and Theme.Holo.Light.DarkActionBar in manifest down android:minSdkVersion to version 11, it SOLVES the problem...
But it generates another problem: you lose AppCompat.Light theme...
But error NullExceptionPointer in actionbar.setNavigationmode is solved..
