    startActivity(ourIntent);
    } catch(ClassNotFoundException e){
        e.printStackTrace();

    }

    }

the manifest

           <?xml version="1.0" encoding="utf-8"?>

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
</application>


</manifest>

Any ideas what's the problem?

Answer 1

change the
within intent-filter tag
action android:name="android.intent.action.Tools
/intent-filter
to
android:name="com.example.taekwondobuddy.util.Tools";

Answer 2

use

Class ourclass = Class.forName("com.example.taekwondobuddy.util." + cheese);

for getting class name with full package name because currently you are missing .util and also make sure you have added all Activities in AndroidManifest.xml

In classes array "Tkd Buddy" is not valid class name so use right naming conventions for classes
