How to set a different java file as launcher

I am new to android and i have created a class in my android project other than the default MainActivity class and i want to start my project with that file. Here is what i added to my manifest file:

<activity
        android:name="com.example.surfaceview.SurfaceViewExample"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.SURFACEVIEW" />

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

And the class that i created:

public class SurfaceViewExample extends Activity implements OnTouchListener {

OurView v;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    v=new OurView(this);
    setContentView(v);
    v.setOnTouchListener(this);
}



@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    v.pause();
}



@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    v.resume();
}



public class OurView extends SurfaceView implements Runnable{

    Thread t = null;
    SurfaceHolder holder;
    boolean isItOK=false;

    public OurView(Context context) {
        super(context);
        holder=getHolder();
    }

    @Override
    public void run() {
        while(isItOK){
            if(holder.getSurface().isValid()){
                continue;
            }

            Canvas c = holder.lockCanvas();
            c.drawARGB(255, 155, 155, 10);//canvas backgroundu boyama
            holder.unlockCanvasAndPost(c);
        }

    }

    public void pause(){ //pause the thread
        isItOK=false;
        while(true){
            try{
                t.join();
            }catch(InterruptedException e){
                e.printStackTrace();
            }
            break;              
        }
        t=null;
    }

    public void resume(){ //resume the thread
        isItOK=true;
        t=new Thread(this); //this parameter means use this run method
                            //which is inside that class
        t.start();
    }


}



@Override
public boolean onTouch(View v, MotionEvent me) {
    return false;
}

}

But the application does not start. I think the problem might be in that line inside the intent filter:

<action android:name="android.intent.action.SURFACEVIEW" />

Can anyone help me with this?

Thanks

Update your manifest with the following code for your activity. This should now launch your activity.

<activity
        android:name="com.example.surfaceview.SurfaceViewExample"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

I hope this helps.
