在Micromax Canvas HD上捕获屏幕截图时出现空指针异常

Question

我在 Micromax Canvas HD 上捕捉屏幕截图时面临空指针异常。

在三星Tab2 和三星Note 800 上工作正常。

我使用了以下代码行。

scrollView.setDrawingCacheEnabled(true);                        
scrollView.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
scrollView.layout(0, 0, scrollView.getMeasuredWidth(), scrollView.getMeasuredHeight());

MailAttachmentImage = Bitmap.createBitmap(scrollView.getDrawingCache()); //Showing Nullpointer exception at this line of code on Canvas HD
scrollView.setVisibility(View.GONE);
scrollView.setDrawingCacheEnabled(false);
scrollView.invalidate();
