i have this message (An existing package by the same name with a conflicting signature is already installed) when compile new release version for my app
my keystore the same im not change any thing else updating from ver 7.1 to ver 7.8


Signing package file (private key). (3.91s)
ZipAlign file. (0.24s)
Installing file to device. Error
Failed to install ord.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package Bokra.app signatures do not match the previously installed version; ignoring!]

can you uninstall this .apk? but that means you can lost data.

i upload this apk to google play and i have users using this app
if upload with another key i will must upload it as new app

 

[MarkusR]

i not spoke about other .keystore, only about your device you will upload .apk from ide.
you check settings in private key window? if it is same as before?

Maybe you previously installed the app with the debug key instead of your key.

 

[ihabsharaf]

Previous installed is the same key

 

[ihabsharaf]

Last app update appeared as new update for all users that mean the key store is right
I’d know what is the problem

 

[Erel]

I'm not sure that I understand. You cannot load your app to Google Play if it is signed with a different key.

Everything is perfect before updating the latest version of b4a 7.8
after update i make some updates in my app
and need to release it for upload to google store

when i compile i have this message

(Signing package file (private key). (3.91s)
ZipAlign file. (0.24s)
Installing file to device. Error
Failed to install ord.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package Bokra.app signatures do not match the previously installed version; ignoring!])


after that
i download
App signing certificate form my account and compare it with my keystore i think its the same key


now what can do to release new update for my app

Nothing has changed in v7.8 related to the key. If you like you can install the old version and try it again.

 

[ihabsharaf]

just upload app to google play without any problem

but may i know why i have this message until now

Nothing has change related to the key. Maybe you first installed the app with the debug key.
