How to start activity from a ListFragment via onListItemClick

Hi im developing a BLE App. After i scanned for devices and Display them into a ListFragment i want to get Services and Characteristics of them. If i implemented that in onListItemClick everything is fine i get the Services and the Characteristics. But now i want a new Activity started while i click on one Item. 

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    rightPosition = position + 1;
    connectToDevice();
    Intent intent = new Intent(getActivity(),ServiceCharacteristicAvtivity.class);
    startActivity(intent);
}

If i do like above my App crashes really looked for a solution but didnt get my failure. Maybe it is so easy that i dont see it. Can someone help me out?

The Log i get is

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.fkoffle.blescanner/com.example.fkoffle.blescanner.ServiceCharacteristicAvtivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

The activity i want to start is just

public class ServiceCharacteristicAvtivity extends AppCompatActivity {

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

}

If you are extending an AppCompatActivity you need to use an AppCompat or any descendant theme.

You can use one of the below themes in the manifest of your activity.

android:theme="@style/Theme.AppCompat.Light"
android:theme="@style/Theme.AppCompat.Light.DarkActionBar"
android:theme="@style/Theme.AppCompat.Light.NoActionBar"

eg.

<activity
        android:name=".Activity"
        android:theme="@style/Theme.AppCompat.Light.DarkActionBar" />

Probably the activity you are calling is extending Activity, while your layout is having elements that comes under AppCompatActivity. So in your activity, do something like this:

public class ServiceCharacteristicAvtivity extends AppCompatActivity {
....
....
}

If it isn't the case, can you share your layout code and acytivity code?

Inside your manifest file, add the following theme.

  <activity
        android:name=". ServiceCharacteristicAvtivity"
        android:theme="@style/Theme.AppCompat.Light.DarkActionBar" />

As your logcat suggests, you need to use Theme.AppCompat or any descendent (like I used in above example).
