I opened my ODK app today and all my data is gone. No saved forms, blank or sent. There were over 150 sent forms here.. is there a way to recover the sent forms?

What is the problem? Please be detailed.

What ODK tool and version are you using? And on what device and operating system version?

What steps can we take to reproduce the problem?

What you have you tried to fix the problem?

Anything else we should know or have? If you have a test form or screenshots or logs, attach here.

I have solved it. I just loaded SD card in my android device yesterday and made if default storage. I was able to get back all app data by changing the default storage. Phew!
