Hello,
I built my .apk with laptop to try my game on my phone and it worked.
Now I’m no more traveling and I come back on my desktop. I built again .apk and now it says it can’t install .apk on my phone cause it conflicts with an existing package.
Fresh install works (tryed on other smartphone) but I need to keep datas.
I checked “Project Settings > Player > Android > Other” settings and Laptop and Desktop are the same.
Any other ideas?
Thank you in advance…
Just uninstall your app from the phone before trying to install again
Fresh install works, but I need to keep my datas…
The issue here is that your APK was signed by different debug.keystore from different machine. You could avoid that by using same custom keystore to sign APK from both machines
Could I find this debug.keystore anywhere to put inside my desktop?
Not sure if that would work, I’d suggest using custom one (take a look at player settings, publishing section)
Yeah yeah, I know where setting is (I didn’t know debug.keystore was different for each machine, I thought the same for the same project).
I hoped there were the debuh.keystore file anywhere in order to save my datas.
I’ll do some research, otherwise I’ll have to manually save datas and I’ll make do the same to testers 
Debug.keystore if I remember correctly is stored under users/username/.Android folder
Yes, I found the file in your directory and I moved from laptop to desktop and it works.
Thank you so much!
