[android-developers] Re: Dynamic TableLayout problem
David,
The output shows you have a null pointer at line 93 of your activity.
Look there for a solution.
Also, I noticed you have System.out.println. Where are you expecting
the println output to appear? You might want to replace that with
Android.util.log.
Regards,
Beth
