Android Question App not installed

[sasidhar]

Hi,

I have made several versions of an application, and overwriting the appln smoothly. Suddenly i started getting "App not installed " message with one of my latest version. I did not change anything in the project, simple string validations kept. checked package name as well, both versions are same. what could be the reason.

As the appln installed in field on several mobiles. and local DB also exists cannot uninstall and resinstall the apk.
Please suggest what is the reason for sudden error.

thanks

you have to ensure that you use the same sign key (tools->Private sign key)

probably wrong! The DB must be on a readable storage. So they are not in the assets... It must be dirrootexternal or so.. And THIS will not changed when you uninstall your app.

Hi,

This App is not in google play or mraket, custom application, not used any sign key, still the issue is coming.

I have released around 15 version, no where I found this issue, moreover each version source i have backup, previous version source code also not working, but already compiled APKs of earlier versions are working.
some minor issue i could not able to trace, and in debug mode also could not see this issue.
