java.lang.OutOfMemoryError:

请求的大小超过了VM限制。 此错误表示Java应用程序试图分配一个数组，该数组的大小大于堆的大小

OutOfMemoryError扩展了VirtualMachineeError类，该类表示JVM已损坏，或已耗尽资源，无法运行

验证应用程序没有存储不必要的信息。 仅存储和维护项目所需的信息 正确执行Java应用程序

protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
// I got error in this line.
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();

        Bitmap roundBitmap = getRoundedCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }
