Android Question App not installed

[Osama_Zaghloul]

Hello everyone,
I have a problem where I am using B4A..
And everything is fine...but the application shows me... "App not installed"
I tried to do something "Release" Then I transferred the app to the phone and the same problem occurred... even in new projects without putting any codes..
Thank you all

Try changing the "package" name (IDE menu "Project"...."Build Configurations") and recompile.

Try changing the "package" name (IDE menu "Project"...."Build Configurations") and recompile.

This will probably solve the issue.

- A common cause for this error is when you have an already installed app with same package name and with a higher #VersionCode. Uninstalling the existing app will also solve it.
- If you are unable to solve it then switch to USB debug mode instead of B4A-Bridge. It will provide more information about the error.
