SVGImageView crashes on Android 5.0 and higher #60

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
Using the following code will crash 5.0 and above with a segfault from the OS:

private FrameLayout mIdCardContainer;
private SVGImageView mIdCardBackImage;
private SVGImageView mIdCardFrontImage;

mIdCardFrontImage = new SVGImageView(getActivity());
mIdCardFrontImage.setId(R.id.img_id_card_front);
mIdCardFrontImage.setLayoutParams(new 
ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 
ViewGroup.LayoutParams.MATCH_PARENT));
mIdCardFrontImage.setContentDescription(getString(R.string.front_of_id_card));
mIdCardFrontImage.setRotation(ROTATION_ANGLE);

// Setup special SVGImageViews for back of card
mIdCardBackImage = new SVGImageView(getActivity());
mIdCardBackImage.setId(R.id.img_id_card_back);
mIdCardBackImage.setLayoutParams(new 
ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 
ViewGroup.LayoutParams.MATCH_PARENT));
mIdCardBackImage.setContentDescription(getString(R.string.back_of_id_card));
mIdCardBackImage.setRotation(ROTATION_ANGLE);
mIdCardBackImage.setVisibility(View.GONE);

SVG frontSvg = SVG.getFromString( idCard.getCardFrontData() );
SVG backSvg = SVG.getFromString( idCard.getCardBackData() );

mIdCardFrontImage.setSVG(frontSvg);
mIdCardBackImage.setSVG(backSvg);

What is the expected output? What do you see instead?
Some devices crash immediately on setting the images others fail miserably when 
the two images are flipped with an animation front -> tap -> back -> tap -> 
crash

What version of the product are you using? On what operating system?
1.2.2-beta-1

Please provide any additional information below.
This works fine on 4.1-4.4.2
This does not work at all on Genymotion, or on certain devices.
The crash after flipping back to the front image crashes on the Samsung S6 
running 5.0.2, but works on a nexus 5 running 5.0.

Thanks for the report.  Can you provide a copy of the segfault message?

Thanks for that.

The good news for me is that this doesn't look like an AndroidSVG fault :)

It looks like the problem is in Skia, which is the 2D rendering library in 
Android.

I've passed this on to the Android bugtracker.  
https://code.google.com/p/android/issues/detail?id=172402

I will probably end up marking this as Won't Fix, but if you have any more 
detail on the cause, please send it through.  For example:

* Does it happen for some SVGs and not others?  If so, are you able to attach 
one of the failing SVGs?
* If you simplify the code - for example, removing the rotations - can you get 
it to stop faulting?  It would be good to find a work-around in case other 
people strike this also.

Sadly I can not attach the svg, its an internal testing one and I dont think 
it'd be the best thing if I sent it out.  NDAs and the like.

I got around it by instead of using the SVGImageView, I had it render to a 
bitmap and used an ImageView to show that.  It worked quite happily there.  
I'll have to try other SVGs and remove the animation to flip between the two 
views and see what happens.

My work around was something like this:
mIdCardFrontImage = (ImageView)rootView.findViewById(R.id.img_id_card_front);
mIdCardFrontImage.setContentDescription(getString(R.string.front_of_id_card));
mIdCardFrontImage.setRotation(ROTATION_ANGLE);

mIdCardBackImage = (ImageView)rootView.findViewById(R.id.img_id_card_back);
mIdCardBackImage.setContentDescription(getString(R.string.back_of_id_card));
mIdCardBackImage.setRotation(ROTATION_ANGLE);
mIdCardBackImage.setVisibility(View.GONE);

The image is pulled dynamically from a server, so this happens asynchronously 
after the image views and its parent is already laid out and sized correctly 
for this to work.

// Changes to how this works to fix the lollipop crash
            // Make the SVG from the data returned from the server
            mFrontSVG = SVG.getFromString( idCard.getCardFrontData() );
            mBackSVG = SVG.getFromString( idCard.getCardBackData() );

            //Scale the image up so it fits on the screen better and isn't tiny or fuzzy
            //Sharpness is preserved because its a vector image. Yay!
            mFrontSVG.setDocumentPreserveAspectRatio(PreserveAspectRatio.LETTERBOX);
            mFrontSVG.setDocumentHeight(mIdCardFrontImage.getWidth());
            mFrontSVG.setDocumentWidth(mIdCardFrontImage.getHeight());

            //Scale here as well, but because mIdCardBackImage is gone, it doesn't have a
            //height or width.  So use the front image height and width.
            mBackSVG.setDocumentPreserveAspectRatio(PreserveAspectRatio.LETTERBOX);
            mBackSVG.setDocumentHeight(mIdCardFrontImage.getWidth());
            mBackSVG.setDocumentWidth(mIdCardFrontImage.getHeight());

            //Render these two images to bitmaps set to a background color of transparent.
            //I did not want to use a function with these since we are using bitmaps and
            //passing them around could quickly lead to memory problems.
            if (mFrontSVG.getDocumentWidth() != -1) {
                //Create the bitmap the same size as the scaled SVG
                Bitmap  newBM = Bitmap.createBitmap((int)Math.ceil(mFrontSVG.getDocumentWidth()),
                        (int)Math.ceil(mFrontSVG.getDocumentHeight()),
                        Bitmap.Config.ARGB_8888);
                //Create a canvas to sit atop the bitmap to allow drawing
                Canvas bmcanvas = new Canvas(newBM);
                // Clear background to transparent
                bmcanvas.drawARGB(0, 0, 0, 0);
                // Render our document onto our canvas
                mFrontSVG.renderToCanvas(bmcanvas);
                //set the imageview to the new bitmap
                mIdCardFrontImage.setImageBitmap(newBM);

                //clean up and call the garbage collection to avoid any potential memory issues
                newBM = null;
                System.gc();
            }

Pretty much using the code sample from the project webpage.  The flip is still 
there, and doesn't crash.  Granted the above somewhat defeats the purpose of 
the svg, but it worked in this case.  

Thank you for making a library that handles SVG.

The Skia folks have asked for more information.  Can you try their suggestions 
and follow up there?
