Android Question Signing old EXISTING app issue

[jemajuca]

Hello.

Because Google requirements I need to update an old app that only needs to change the targetSdkVersion in manifest.
I used B4A v10.00 and I think there is no need to update the program.
The private sign key is correctly configured in B4A. No errors when compile.
When triyng to upload the updated apk, it shows this error:

"You uploaded an APK with an invalid signature (learn more about signing). Error from apksigner: ERROR: MIN_SIG_SCHEME_FOR_TARGET_SDK_NOT_MET: Target SDK version 31 requires a minimum of signature scheme v2; the APK is not signed with this or a later signature scheme"

I'm afraid that any change to the signing process will cause problems with my client's updates.

Any idea how to proceed?

Whats written in your manifest ?

Here it is:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.

I used B4A v10.00 and I think there is no need to update the program.

This is a mistake. First step is to update to latest version with latest SDK.

First step is to upload

Erel meant to say update.
