AndroidSVG chokes with NPE while parsing one SVG file in particular #28

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
I'm using AndroidSVG to display SVG kanji stroke diagrams. When I try to 
display one diagram in particular a Null Pointer Exception is caught. Here's 
the stack trace from a recent occurrence:

java.lang.NullPointerException

And here's line 66 and 67 from my code:

InputStream is = new BufferedInputStream(new FileInputStream(svgPath));
SVG svg = SVG.getFromInputStream(is);

The code was able to handle the other dozen or so diagrams I threw at it, so I 
think the problem might be somewhere in AndroidSVG. After some testing I've 
determined that it's not an issue of the file not existing - I've verified that 
it's in the proper directory. In an effort to isolate it from potential issues 
from my code, I attempted to load the SVG in a separate, basic app that I 
drafted exclusively to test AndroidSVG functionality; that app threw the same 
error.

I've attached the image that causes the issue, I hope it helps. If it's an 
issue of a malformed SVG, let me know and I'll redirect the issue to the group 
responsible for making the original file.

Hi. Thanks for the report, and thanks for using AndroidSVG.

I am pretty sure this is also a duplicate of Issue 13.

To work around this bug until 1.3 is released, replace the comma between path 
command coordinate sequences with a space.

For example on line 43 of that file, the path definition is:

d="m13.5,67.39c1.62,0.99,2.5,0.99,4.12,-0.51,4.43,-4.09,7.63,-7,18.45,-17.66"/>

change it to:

d="m13.5,67.39c1.62,0.99,2.5,0.99,4.12,-0.51 4.43,-4.09,7.63,-7,18.45,-17.66"/>

Note the space after the "-0.51".  It looks like that is the only occurrence in 
that file.
