ArrayIndexOutOfBoundException on calling View.draw(Canvas) method

I am trying create bitmap from a Linear Layout in a asynctask(). Please find the code here:

while (running) {
        count++;
        v1.draw(new Canvas(bitmap));//I am getting exception here
        //sleep thread to give some lag
    try {
            Thread.sleep(30);
        } catch (InterruptedException e) {
            e.printStackTrace();
            throw new RuntimeException(e.getMessage());
        }

        System.out.println("Bitmap : [ " + count + " ] >>>>>>>> SAVED. ");

    }

And I am getting the error as:

You canuse try catch block for this exception. Like below : 

while (running) {
    count++;
    try {
        v1.draw(new Canvas(bitmap));
    } catch(ArrayIndexOutOfBoundException e){
        e.printStackTrace();
    }
    try {
        Thread.sleep(30);
    } catch (InterruptedException e) {
        e.printStackTrace();
        throw new RuntimeException(e.getMessage());
    }

    System.out.println("Bitmap : [ " + count + " ] >>>>>>>> SAVED. ");
}
