Android App crash updating Marks position #156

Closed Userpack4 closed 8 years ago

Userpack4 commented 8 years ago

Hi all, I've implemented glob3 in my android app. I've created a BluMarbleLayer and a Mark in onCreate method. Then, in a Timer I have a routine "update" that is run every 1 seconds. In the update routine I change the Mark position via setPosition with a new Geodetic3D position (lat, lon alt) After some seconds I have this error and the App crash:

java.lang.NullPointerException
            at org.glob3.mobile.generated.Mark.createGLState(Mark.java:122)
            at org.glob3.mobile.generated.Mark.render(Mark.java:854)
            at org.glob3.mobile.generated.MarksRenderer.render(MarksRenderer.java:194)
            at org.glob3.mobile.generated.CompositeRenderer.render(CompositeRenderer.java:147)
            at org.glob3.mobile.generated.G3MWidget.render(G3MWidget.java:212)
            at org.glob3.mobile.specific.ES2Renderer.onDrawFrame(ES2Renderer.java:63)
            at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1531)
            at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1248)```
Anyone can help me to find a solution ?
Thanks in advance.

Hi @silvioItaly

It looks like you're calling G3M methods from am invalid thread, please take a look to #17
