Re: [android-developers] Re: Null pointer exception
Sorry if this sounds silly: you might want to set a breakpoint on line:
startActivity(i);
when you hit that point, examine "i" carefully. From your log, I wonder if
the act of starting the activity invokes your current code, inducing an
infinite loop. Also, if it were my code, I would want to ensure I catch all
uncaught exceptions. Around your code that you feel is failing, I would
catch the general "Exception" as well as the AndroidRuntimeException (cannot
remember if I've spelled that perfectly right), and print out the stack
frame from the exception that was caught. that might yield additional info.
Finally, further assistance from the forum, you may want to include more of
your code. You probably have something special in there you don't want to
share... just make what you post generic enough so we can see the construct
of your whole activity.
all the best, steve.

Re: [android-developers] Re: help needed with project: preview image on a opengl texture
On the physical device, in settings->about phone-> build_number., there's a long description there that more precisely identifies the revision of software being used. In the first software revision for Droid, for example, it will say ESD20 in the midst of that long string. Also, I'm wondering, is it sufficient to exit the application to restore the device's normal behavior? I appreciate the information if you're willing to reply. Thanks! Stephen.

Re: [android-developers] help needed with project: preview image on a opengl texture
Could you please answer the following? What's your platform? (Eclair/Droid/Donuts/Magic ... etc) Also, what revision of the software (e.g. ESD20)? Thanks!
