styles.xml with android version qualifier cause app crash

Issue

My app use a different style for minimum version of Android:
My app use a minimum version:   API 9  Android 2.3 (Gingerbread)

I use Version qualifier for assign a different style to every Android version:

My styles file from values/style.xml is:

<style name="AppTheme" parent="android:Theme">

</style>

My styles file from values-v11/styles.xml (if device is Android 3.0 or later):

<style name="AppTheme" parent="android:Theme.Holo">

</style>

My styles file from values-v14/styles.xml (if device is Android 4.0 or later):

<style name="AppTheme" parent="android:Theme.DeviceDefault">

</style>

The following .xml is only a fragment of AndroidManifest.xml

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
</application>

---

My issue is: When the app runs in my phone, the app crashes unexpectedly, I know that my issue is in the use of version qualifiers.

Solution

You use Android 2.3 for more compatibility. On Android Studio, the activities for minimum versions (like Android 2.3 Gingerbread or earlier) are created automatically with the following code:

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

The ActionBarActivity isn't compatible with styles different to AppCompat

Try to convert from ActionBarActivity to Activity:

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}
