Hi
I had version 3.8 of b4a and it worked very well, but I upgraded to version 8.5 and I have the following problems.

when I install the app on the mobile it shows the following error:

1) the app has conflict with another package already installed (does not let install it).

2) I take another app that ran well in 3.8, I compiled it in version 8.5 and when I install it, it shows the message: the application will close and stop working.

3) I compile another app that ran well with version 3.8 and the mobile shows the message: that a riskware has been detected, that the provider has low reputation and that it may involve a risk.

4)compile the appcompat program (menus) and the mobile shows the message: application not installed, because the package is damaged.

I do not know what to do, I'm disappointed with version 8.5
help me.
Thank you

Don't be. Everything will be solved.

1) You were using the old debug key. At some point it was changed. You have two options: uninstall the existing app and then run it again or use the old debug key (https://www.b4x.com/android/forum/threads/conflicting-signature.71219/#post-452635)

2) You need to check the logs and post the error. I guess that you changed the targetSdkVersion to 26 without understanding that you need to handle runtime permissions: https://www.b4x.com/android/forum/threads/67689/#content
This is of course not related to B4A version.

3) Use your own signing key and it will be solved.

4) Start with running this example: https://www.b4x.com/android/forum/threads/appcompat-with-toolbar-minimal-example.79896/#content
