Question

Hello good people of Stack Overflow, I am having trouble with an application I am writing, as evident from my title. What I am trying to do is simply play a song, looping, and whenever the screen is touched for a sound effect to play. I am doing this using the libgdx library, as I am attempting to learn it for more advanced use. Here is the code.

package main;

import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.audio.Music;
import com.badlogic.gdx.audio.Sound;

public class AudioExample implements ApplicationListener {
    Music music;
    Sound sound;

    @Override
    public void create() {
        music = Gdx.audio.newMusic(Gdx.files.internal("data/02 - Butterfly.mp3"));
        sound = Gdx.audio.newSound(Gdx.files.internal("data/Collision8-Bit.ogg"));

        music.setLooping(true);
        music.setVolume(0.5f);
        music.play();
    }

    @Override
    public void dispose() {
        music.dispose();
        sound.dispose();
    }

    @Override
    public void pause() {
    }

    @Override
    public void render() {
        if (Gdx.input.justTouched()) 
            sound.play();
    }

    @Override
    public void resize(int arg0, int arg1) {
    }

    @Override
    public void resume() {
    }

}

And here’s the activity.

package com.habel;

import main.AudioExample;

import com.badlogic.gdx.backends.android.AndroidApplication;

import android.os.Bundle;

public class SuperAwesome extends AndroidApplication {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        initialize(new AudioExample(), false);
    }
}

The app will not even launch. Thank you for your help in advance.

Your log message says:

06-11 22:12:40.809: ERROR/AndroidRuntime(19767): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.habel/com.habel.SuperAweomeActivity}: java.lang.ClassNotFoundException: com.habel.SuperAweomeActivity in loader dalvik.system.PathClassLoader[/data/app/com.habel-2.apk]

You spelled Awesome as Aweome (probably in your manifest), so it can’t find your Activity

(also, it look like it’s called SuperAwesome not SuperAwesomeActivity)
