App signature not matching
When installing with
java -jar bundletool-all-0.10.2.jar install-apks --apks=fairchat.apks
on a device where the fairchat Qt App as been installed from Google Play Store (not home brewn) then we get:
08:49:17 E/SplitApkInstaller: Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.osalliance.rocketchatMobile signatures do not match the previously installed version; ignoring!
It can be installed after de-installing the Qt fairchat app.
Tested on two devices.
