I have a phone running Cyanogenmod, which is an AOSP derivative. It lacks Google Play.
I installed Textra as the messaging app some time ago using
adb install com.textra.apk. Textra was recently updated to version 2.28, so I need to update the app.
adb install com.textra.apk resulted in a
INSTALL_FAILED_ALREADY_EXISTS (this was expected). Using
adb install -reinstall com.textra.apk succeeded, but I still have the down-level version 2.26.
I don't want to uninstall Textra because I'm concerned it might wipe my existing database of text messages.
How do I use ADB to update an app that is already installed?
