Installation of signed Android build fails

Questions & Answers

Hello,
I’m trying to get my game signed and ready for Android but I’m having problems installing it on a device. I’ve used the keystore generation in Player Settings to sign it, but when I do Build and Run in Unity I get this error:

Unable to install APK!
	pkg: /data/local/tmp/Package.apk

Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]

UnityEngine.Debug:LogError(Object)
PostProcessAndroidPlayer:UploadAndStartPlayer(String, String, String, String, String, Boolean, Single, Single&, Boolean) (at C:/BuildAgent/work/6bc5f79e0a4296d6/Editor/Mono/BuildPipeline/PostProcessAndroidPlayer.cs:780)
PostProcessAndroidPlayer:PostProcess(BuildTarget, String, String, String, String, String, String, BuildOptions) (at C:/BuildAgent/work/6bc5f79e0a4296d6/Editor/Mono/BuildPipeline/PostProcessAndroidPlayer.cs:402)
UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

I can get it to Build an apk file without complaining, but when I try to install it on my device through a file manager I get a generic Installation failed message there as well.

Do I need to install some sort of certification profile on the device for it to be able to install my signed app, or should this work?

Ok, to answer my own question, you do not need any certification profile to install a signed app.

My mistake was that I had moved jarsigner.exe from its original place in the java SDK, when I put it back the signing worked. For some reason Unity did not output an error when I built with the jarsigner moved.

What made me realize my error was that I did a cert verification on my file, which at first didn’t even work cause the jarsigner.exe was in the wrong place. Then when I had moved it, it showed the signing hadn’t taken place.
To do a cert verification you do this:

jarsigner -verify -verbose -certs YOURFILE.apk

(I actually saw that in some Unity doc, I think)
