Caused by: java.lang.NullPointerException
            at com.example.andrei.sunshine.SettingsActivity.setupActionBar(
            at com.example.andrei.sunshine.SettingsActivity.onCreate(

This is the line : getActionBar().setDisplayHomeAsUpEnabled(true);

And the AndroidManifest is :



Please help me

If your SettingsActivity
extend ActionBarActivity
, your getActionBar();
will be available.

public class SettingsActivity extends ActionBarActivity {
    protected void onCreate(Bundle savedInstanceState) {
        //If you use support library

See the documentation
for more info.
