Even if start-up goes right, the first configuration change makes the screen go black. The program still runs and no GL or EGL calls signal any errors. > > Here's the weirdest part - if I omit the runOnUiThread() stuff and simply call setFormat() from my render thread, it fixes the problem and the program runs 100% solid on Optimus no matter much beating I give it - randomly pressing Home and Back while rotating the device wildly, putting it to sleep and waking it back up, the renderer always handles the native window changes correctly and renders just fine. > > I'm at a loss, does anyone have an explanation? > > -- > You received this message because you are subscribed to the Google > Groups "Android Developers" group. > To post to this group, send email to [email protected] > To unsubscribe from this group, send email to > [email protected] > For more options, visit this group at > http://groups.google.com/group/android-developers?hl=en > --- > You received this message because you are subscribed to the Google Groups "Android Developers" group. > To unsubscribe from this group and stop receiving emails from it, send an email to [email protected]. > For more options, visit https://groups.google.com/groups/opt_out.
