Issues in handling Marks

[octavianiLocator]

Hi guys,

Hope you are all good. We have resumed development on our Android app and now have integrated G3M. The globe is loaded and centered on the current location Mark, showing some Marks around it. When the user moves, Marks therefore need to be added and removed dynamically.
Please help us understand why the following 3 issues occur.

1. java.lang.NullPointerException

Thank you in advance and wish you a great week!

EDIT
The issues seem to occur when removing Marks and when clearing the globe of all Marks.

Add mark:
`Mark markM = new Mark(....)

    // Add Mark to MarksRenderer
    `_marksRenderer.addMark(markM);`

Remove Mark:
_marksRenderer.removeMark(mark);

Clear globe of all marks:
_marksRenderer.removeAllMarks();

Should these methods be called in a G3MContext (the RendererThread)?

Hi octavianiLocator
It's a little hard to know what's happening without more information, so if you want assistance you should explain a little more what are you doing.
Anyway:

1. NullPointerException --> You are trying to access to something null, review where you are using this MarkerRenderer what's is null here.
2. Same thing, it's and IndexOutBoundsException... so, review your arrays...
3. You are trying to render something with glob3 in the Thread that is Non-OpenGL. You can see a very similar issue here: Destroying and Recreating the Globe #53

Thanks for using Glob3 Mobile!

Hi @mdelacalle and thanks for your quick reply. I have edited the issue to reflect extra info.

EDIT
Looking at issue 2, doesn't it seem that it's caused inside g3m context?

[octavianiLocator]

Which is the recommended method for adding/ removing marks (one by one, or all at once)?

@octavianiLocator

Please, the next time, fill individual issues per each problem. It's much more complicated to answer several of them in the same issue.

Related to the 2:
May be your problem is you're removing the marks before the effect "zoomInAppears" ends. Please try setting this property to false before adding the Mark to the MarksRenderer. Note the method Mark::setZoomInAppears(bool zoomInAppears)

[octavianiLocator]

Thanks, @DiegoGomezDeck

Setting the "zoomInAppears" effect solved the issue.

@octavianiLocator can we close this?

[octavianiLocator]

@DiegoGomezDeck yes, sure
