Hi
Excuse me to contact you through mail. But i have a very typical question regarding Android Support library.
Please see my question in stackoverflow -
illegalstateexception - Illegalstate exception android fragmentactivity on backpress - Stack Overflow
Also please tell how to debug such issues . Iam unable to reproduce this issue and only happens for my app customers.
Also read the article written by Alex about this - Fragment Transactions & Activity State Loss | Android Design Patterns
But i think my problem and eve nstacktrace is different from this issues
Please help.
