I created pretty basic Android application with ActionBar and 2 tabs. It worked OK. Then I added locale resource directory res/values-de and inside it strings.xml with strings translated in German language. I changed language on my Nexus7 to German and application is unable to start after deployment. I got the same problem on emulator.
Please can you help me make this application running with some non default locale on my mobile device? In my case German...

MainActivity code without TabListener:
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
String label1 = getResources().getString(R.string.label1);
Tab tab = actionBar.newTab();
tab.setText(label1);
TabListener<Tab1Fragment> tl = new TabListener<Tab1Fragment>(this,
label1, Tab1Fragment.class);
tab.setTabListener(tl);
actionBar.addTab(tab);
String label2 = getResources().getString(R.string.label2);

tab.setText(label2);
TabListener<Tab2Fragment> tl2 = new TabListener<Tab2Fragment>(this,
label2, Tab2Fragment.class);
tab.setTabListener(tl2);

}
Reported line 20 in error is actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
strings.xml with German text is
<string name="app_name">TabActionBar</string>
<string name="hello_world">Hello world!</string>
<string name="menu_settings">Settings</string>
<string name="title_activity_main">MainActivity</string>
<string name="label1">Eins</string>

Check out this discussion: Action Bar - Menu Button - Missing
By any chance, do you also have the styles.xml file inside the values-de folder? This could cause problems with the ActionBar becoming NULL.
