Hi list,
I'm having hard times getting my GL thread (from GLSurfaceView) to
trigger some code execution within the UI thread (from Activity). I
tried it in every possible way (well not every, I missed at least the
good one) none worked.
My idea was to get something called from the UI thread (to update some
widgets) when the surface is effectively created. So I added to my
onSurfaceCreated method the following call:
mActivity.runOnUiThread(mUpdater);
mUpdater is a member of my GLSurfaceView sub-class. It is declared as
following:
private Runnable mUpdater = new Runnable() { void run () { ... } };
This compiles, but when my GLSurfaceView sub-class is constructed a
NoClassDefFound exception is thrown, telling me that the class
com.my.package.MyGLSurfaceView$1 is not found.
Here's the log:

The line 297 in MySurfaceView.java is:
private Runnable mUpdater = new Runable () { public void run ()
{ [...] } };
What have I missed ?
Thanks for your help.
Floof.
