Unable to install APK

Questions & Answers

Hi

I have a project aka Game_1 which I replicated from previous project aka Game_0. I am trying to install apk of Game_1 in my device but I get error “unable to install apk”.
My device already contains an APK of Game_0. When I uninstall APK of Game_0, I can install Game_1 apk.

Both apk have different product name and different package names. They both are build by same keystone file. My unity version is 5.3.3 and I have also tried on 5.4.1 but same error pop ups.

I have also made sure that install location is automatic in player setting. I was continuing the same process from last 6 months and everything was going along very nicely. Now when I do the same stuff, I am getting installation error.

Can anyone tell me if there is some hidden file which makes both APK’s identical for device to install ?

Error Msg is something like this

UnityException: Unable to install APK!

There has to be something still the same. Since your APK name seems to be “Package.apk” that might be the problem. The name of the APK should be equal or similar to your bundle identifier / package name.

Using the same key (from the same keystore file) should be no problem.

Have you tried to install the APK manually? Have you checked the logcat output?
