Android Question "App not Installed" (when using Services)

[maleche]

B4A Version 6.3 gives me an error "App not installed" on the device when compiling with Service Modules.
No compile error in logs unfiltered or not.
All other programs compile and load to device without errors.
any suggestions?

Did you unistall the previous version? (it often occurs when you use the same package name)

 

[maleche]

no previous version of the app exist on the device . new initial app.
thanks for your reply .

Are you doing a debug compile or a release compile? If it's a release compile, is it signed? You might want to look at this thread.

[maleche]

yes. I tried debug and release, and with signing.
I also tried 3 different android devices and still it did not install .
I Uninstalled and reinstalled B4A, SDK, and , JRE and it won't install if there is a service module with the compiled code.
it there a test code with a service module I can try?
thanks again

It is not related to the service module.

Try to change the package name and run your app. Does it work?

 

[maleche]

I have changed the name and ensured the package name does not exist.

 

[Erel]

The name is not important. Test it with a different package name.

Are you connected with B4A-Bridge? If so then switch to USB debug mode and monitor the unfiltered logs.

I tried the BLE example which compiles as B4A Example. I received the "Application not installed" and "Package with that name and different signature already installed".
I deleted the app "B4A Example" and changed the name to "BLE_Test" and still received the above error and not installed.
where can i find how to connect with usb to upload to device?
thanks.

I deleted the app "B4A Example" and changed the name to "BLE_Test" and still received the above error and not installed.

The app name is not important. Only the package name. Change the package name (Ctrl + B) and test it.

hi,
I have a similar problem. The application error not installed it I note when the device is switched off with the open application. It does not use database services. What can I check?
Thanks

Have you tried to uninstall the existing app?
If you don't find the existing app then try to change the package name and install again.
