Answer 1

Вы можете сделать это с интерфейсом

создать интерфейс в вашем AsyncTask , и создать метод, который будет использоваться в качестве обратного вызова

public class ShowCustomProgressBarAsyncTask extends AsyncTask<Void, Integer, Void> { 
    interface ProgressListner { 
     public void onProgressChanged(int progress); 
    } 
    private ProgressListner listner; 
    public ShowCustomProgressBarAsyncTask(ProgressListner listner) { 
     this.listner = listner; 
    } 
    //..your remaining codes 

    @Override 
    protected void onProgressUpdate(Integer... values) { 
     //..your remaining codes 
     listner.onProgressChanged(values[0]); 
    } 
} 

Затем выполните это интерфейс в вашей деятельности.

Также передайте экземпляр интерфейса через конструктор в AsyncTask.

Затем с помощью этого экземпляра вы можете обратный вызов метода, который будет передавать значение прогресса

public class GamePlayActivity extends Activity implements ProgressListner{ 
    //.. your remaining codes 

    new ShowCustomProgressBarAsyncTask(this).execute(); 

    public void onProgressChanged(int progress) { 
     a = progress; 
    } 
}
