Android Question App not installed. The package appears to be corrupt.

[GuyBooth]

With a recently reinstalled B4A v 7.8 and the latest android and java releases, I am dead in the water.
A clean app with very little code compiles, but on installation to my tablet running Android 7.0 I receive the message:
"App not installed. The package appears to be corrupt".

It seems to install ok on my S3 which is running Android 4.4.2 (although I crashes, but I suspect that is a coding mistake on my part).

I would uninstall the app and reinstall it - but it's a new app, so there is nothing in the Apps list to uninstall.

although I crashes

You maybe should start with this issue....

can you reproduce it with a example project?
Upload the project. File -> Export as zip

 

[GuyBooth]

Here it is ... will only produce a grey screen, but if you can get that far it is further than I can get.
It works ok on my Galaxy S3 with 4.4.2, but I need it to test a later version Android devices (7.0)

Installed fine here. I did change the targetSdkVersion to 26 to avoid a conflict with an existing app.

Try to change the package name and run it again.

I tried that - in fact, I built a whole new app with a new name. Same result.
Also tried uninstalling and reinstalling the SDKs
Also tried uninstalling and reinstalling B4A

Fresh eyes this morning though - the first screen on the tablet that comes up when the compile is finished and it tries to install says:
"Do you want to install an update to this EXISTING application?"
But I can't uninstall the "existing" application because it doesn't show up in the application list.

Change the package name to: b4a.example11111

What happens?

Change the package name to: b4a.example11111

What happens?

Yes that works .... the package name was still set at b4a.example.

b4a.example does not show up in my apps list on the tablet though - so not sure why these messages were showing up.

 

[Erel]

Yes that works .... the package name was still set at b4a.example.

Note that I already asked you to change the package name in post #4...

You can try to uninstall it with adb uninstall b4a.example
A tablet restart might help.

I appreciate that Erel - we're not all perfect ...
I had changed the application name, not the package name.
