Java class not working

Question

I want the code shown here to run all the time:

class secondClass extends TimerTask {

    MediaPlayer mp;

    public void onCreate(Context context) {
        mp = MediaPlayer.create(context, R.raw.flyinghome);
    }

    public void run() {
        float x = (float) Math.random();
        float y = (float) Math.random();
        mp.setVolume(x, y);
    }

    public static void main(String[] args) {  
        secondClass task = new secondClass();  
        Timer timer = new Timer();          
        timer.scheduleAtFixedRate(task, 0, 2000);           
    }  
}

How can I have this TimerTask running a the same time as the MainActivity class if The MainActivity class extends Activity and implements OnCLickListener.

Answer 1

As you can read here

Each timer has one thread on which tasks are executed sequentially.

You can schedule a task to run inside that thread, using one of the schedulling functions, such as:

Timer t = new Timer();

t.schedule(new secondClass(), delay);
//delay is the amount of time in milliseconds before execution.

since you want it to run all the time, you can consider to use schedule(java.util.TimerTask, long, long) that schedules a task for repeated fixed-delay execution after a specific delay.

Timer t = new Timer();

t.schedule(new secondClass(),  delay,period);
//delay is the amount of time in milliseconds before execution.
//period    amount of time in milliseconds between subsequent executions.

An advice: i would change the class name to SecondClass, since the class names use to be capitaliced.

You could also consider using an Android service.
