Hi,
I am trying to intall dmengine for the second time on my device, it worked fine for the first time but now I get a Failure [INSTALL_FAILED_ALREADY_EXISTS].
Of course the app from my device and deleted every file related to Defold
Anyone know how to truly clear the device from every piece of dmengine to be able to install a new one? (exept factory reset obviously)
What type of device are you using? Android or iOS?
I use an android device
Did you change the package name in game.project, or could it be that you have another app installed with the same package name?
Are you using adb install -r? Also if there are multiple users then it has to be removed from all.
I tried adb installl -r, it does this
I feel like I am using it bad 
@britzl I don’t understand, what is the package name in game.project ?
Sorry to be so noob
The command is:
adb install -r dmengine.apk
Try this and see if the problem still happens.
It worked ! Thank you guys !
Open game.project, scroll down to the Android section. There’s a field named Package Name. The package name should be unique. If you already have an app with the same package name you’ll get INSTALL_FAILED_ALREADY_EXISTS. What do you have in the package name field currently?
