My apk works just one time

Unity Engine

Hi, I’m making a little android game. I build the apk without errors, just some warnings like this:

“Compressed texture t_79 is used as icon. This might compromise visual quality of the final image. Uncompressed format might be considered as better import option. UnityEngine. GUIUtility :processEvent(Int32, IntPtr)”

I can install the Game and play it normally, but if I uninstall the game and I try to install it again I get the message:

“The application was not installed”

If I build the apk again i have the same problem, I can install it but just one time. I tried in a few different smartphones with the same result. At last I tried to install in one phone, then send to another and install in it, just the same, works only one time in the two phones.

Someone has any idea to resolve this problem?
TY so much!!

How are you installing and uninstalling it? I generally use “adb install mygame.apk” and “adb uninstall com.MyCompany.MyGame”

I’m not using the console, I’m doing it in the comun way, I’m using the graphical interface of android, clicling on de apk to install it and holding press, selecting unistall to unistall. I’m doing it wrong?

Not sure, but you might try my suggestion also. Or you can try using Build and Run from Unity. So two options to try.

Maybe I’m not explaining correctly or I dont understan you, my english sucks sorry … But I’m talking about real installation in a real Smartphone. I build the apk, i put in my phone and then i have this situation. And it’s not my phone’s problem because I tried in 5 different Smartphones.

Yes, I am suggesting to install a different way, actually suggested two different ways to avoid the error. “adb install” will install on the phone, “adb unintall” will properly uninstall it. The Unity Build and Run does both, you might want to try that. Install the APK directly from Unity to the smartphone.

But my concern is that the project has a problem that then affects me when uploading it to Google Play.

Then test on your device first as I mentioned, before uploading to Google Play. Personally I’ve never installed as you suggest, I suspect the issue is only is how you are installing and uninstalling. My suggestions may fix that.

I did it as you suggested and it works well !! I can install and uninstall without any problem with the same apk. So I assume that I was doing it wrong … Thank you for your time and help!
