Andengine new Activity - Manifest

Question

I want to start my Level1.class Activity with this code:

public class OverviewChapter1 extends Scene

SceneManager.mainScene.runOnUiThread(new Runnable() 
{
    public void run() 
    {
        SceneManager.mainScene.startActivity(new Intent(SceneManager.mainScene, Level1.class));
        SceneManager.mainScene.finish();
    }
});

However, I get this error message:

FATAL EXCEPTION: main
android.content.ActivityNotFoundException: Unable to find explicit activity class 
{de.davidtheobald.thorsrevengeapp/de.davidtheobald.thorsrevengeapp.chapter1.Level1}; 
have you declared this activity in your AndroidManifest.xml?

How I define the activity in my manifest file?

Answer 1

Add Activity for Level1.class in your AndriodManifest.xml file...

<activity android:name="YourPackage.Level1"> </activity>
