I get just blank white screen while using svg-android

Question

Purpose: I want to display an SVG image file using preferably an ImageView.

Attempt 1:

• I'm using the svg-android library to do that.

• I'm following their tutorial word for word. I just copy pasted their code into my onCreate, commented out my app code from onCreate.

  I have a splash screen coming before this, but I doubt that'll interfere with this in anyway. In any case, I'll just change the launch intent and post an update.

• I've added their jar into the libs folder and referenced it.

Result 1:

I'm testing on samsung galaxy I93000 (International version)

All I get is a white screen.

No compilation or runtime errors.

Logcat output is as follows:

Update 1:

I've tried making the activity that shows SVG graphic as the main activity from the manifest. There is no change in results.

Update 2:

Trying another library/way to do this - ImageView with SVG Support. Will post back with results.

Update 3:

Just so you know, I've already taken a look at SVG support on Android. The answers there do not really provide a native solution. One workaround would be to create static html pages, one for each svg, referencing the SVG js library. This doesn't seem maintainable at all. I would be that person people curse when they look at legacy code.

As you might have guessed the above trial didn't work out quite well.

Answer 1

You've probably already found a solution, but for future reference:

All I get is a white screen.

No compilation or runtime errors.

You probably need to disable hardware acceleration for the ImageView that you're using:

imageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

I had this exact same problem with a fork of svg-android and it was solely due to hardware acceleration.

Answer 2

Ok, after one complete sleepless night, this is what I have. :)

Hope 1:

*TPSVG_Android_SVG_Library:* (This is what I used i.e. My Stamp of Approval ;) )

Tried this blessed person's library. Worked like a charm. He extends his custom view from View so you have most of the basic parameters for layouting. It has just one contributor. I'm slightly averse to using it on production stuff, atleast on a long term basis. But kudos to his work and many thanks as it satisfied my immediate need.

The usage is pretty straight forward for this one, anywho I shall describe it roughly.

• Download the repo as a zip and import it into eclipse
• Add it as a library project into your project (Project Properties -> Android)

• Use it like so in onCreate:

  SVGView svgView = (SVGView)this.findViewById(R.id.svgImage); SVGParserRenderer image = new SVGParserRenderer(this, R.raw.anime); svgView.setSVGRenderer(image, null); svgView.setBackgroundColor(Color.WHITE);

• I've used a FrameLayout to position this. lotta trial and error was needed as this doesn't show up in the WYSIWYG editor for android. You may temporarily replace this with ImageView and deal with the formatting.

• Any parameters used in this tag that do not belong in the View class will cause compilation errors

ISSUE: I haven't quite figured out yet how to switch drawables(SVG) on this View during runtime. If anyone figures that out, kindly post the procedure.

Hope 2:

Vectoroid:

This one seems promising. They have a few vector based apps out along with the library. I couldn't quite figure how to use this to load a SVG drawable (seems like that's not supported yet). But wait! here on their blog they say that they've implemented the "SVG to drawable" and will be releasing it out soon. Yay!
