github.jorgecastillo.svg.SvgPathParser.ParsePath() about androidfillableloaders

[aligkts]

I have same issues.I could not solve it.

[Letme]

Can you2 paste some code producing this or what did you follow when this appeared?

[Letme]

(I am not on computer but lets get more info).

Can you print/share the value of you path (SvgPath.Bag.path)? It seems like that is NULL...

[Letme]

(your replies are a bit messed since you reply on mails)

Ok, so since public FillableLoaderBuilder svgPath(String svgPath) takes String and you feed it with val we can start with that alignment. Here I assume that path contains something like string with "\n" for end of line characters, some string numbers with dots and stuff (so not OS path)...

[aligkts]

Yes my path contains "\n" and "+".What do you think?

[Letme]

Did you try to change the path variable from val to String? It seems like the length is somehow null and that hits the null pointer exception.

[aligkts]

It is already 'val path: String?' when I change it to 'path: String?',this does not refers path 'val path= SvgPath.Bag.path'

[Letme]

I would indeed change val path= SvgPath.Bag.path to String path= SvgPath.Bag.path to make it more explicit. You confirmed with debugger that path then contains a proper string which is passed to svgPath()? Just go step by step with break points if logcat print messages are not revealing enough.

[aligkts]

In Kotlin language, val path= SvgPath.Bag.path refers to Java's String path= SvgPath.Bag.path

[aligkts]

Path does not comes null I checked that but I have no idea about what is the problem :(

[Letme]

Kotlin... huh I am indeed rusty. Can you again paste the LogCat error and a nicely formatted example? I was on Java, but this might be issue with Kotlin calling Java?

[aligkts]

java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.String.length()' on a null object reference at com.github.jorgecastillo.svg.SvgPathParser.parsePath(SvgPathParser.java:52) at com.github.jorgecastillo.FillableLoader.buildPathData(FillableLoader.java:374) at com.github.jorgecastillo.FillableLoader.onSizeChanged(FillableLoader.java:224)

this is LogCat error

[Letme]

So the error reads exactly what I said, but what you pasted before was .build() method - so I assume logcat marks that line as failure in your application? You will have to give a lot more information if you want me to help you debug this, because now I can only guess.

You can check it from these links easily.

OK few ideas (remember don't know Kotlin syntax or background so might be totally off):

• I assume you confirmed without this lines the fragment loads (put a textview in to start with), because I remember you have to inflate fragments and stuff like that
• Maybe a simple var string instead of enum class would do the trick (although I read over Kotlin help on enum class and it should return String like you say it does)
• For future you are missing fillableLoader.setOnStateChangeListener(this); later on, because I see your error originates from: com.github.jorgecastillo.FillableLoader.onSizeChanged(FillableLoader.java:224), which might also be something coming from onStateChange trigger in second loop (error is kinda short and does not map to your code so I am guessing again).
