I managed to solve the problem, although in my opinion it did not make much sense. In the Androidmanifest.xml file I had to change the name of Activity

<activity android:name=".ListActivity"></activity>

for:

<activity android:name="android.app.ListActivity"></activity>

And here’s why I thought it was weird: the other two activities I have in my project are in the same folder as this one. And in the manifest file they are set as:

<activity android:name=".PreferencesActivity"></activity>
<activity android:name=".MainActivity">

Same way this one was, but unlike this one, these two work perfectly
