Somehow I am getting an nullpointer when trying to execute my intent using startActivity. The only problem is that I am having the same statement in a different class. And that one is executed correctly without any problem. This is the piece of code which is causing the error:
public class GetPreferences extends Activity {
String result, Gebruikersnaam, Wachtwoord, LicentieCode, DeviceId, GebGUID;
FeatureSettings settings;
StringEntity seParams;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.frmlogin);
Intent startApp = new Intent(this, actMain.class);
startApp.putExtra("afterLogin", 1);
startActivity(startApp);
}
this is the error log:

and here is the defintion of the class in my manifest:
<activity
android:name="com.koeriers.erasmus.actMain"
android:label="@string/app_name" >
</activity>
I know that my actMain class isn't even being loaded, because I've added a Log.e statement. And that isn't even being executed. So it must be the startActivity part, but I just can't see what is going wrong. So I hope you guys can help me out.
Thanks in advance.
@edit
here is my actMain.class
