Android Studio 3.0 Unsigned Apk Not Installing

问题:

After upgrading to android studio 3.0 the debug apk is saying App not istalled.

The package appears to be corrupted

回答1:

Looks like we can not directly use the apk after running on the device from the build->output->apk folder.

After upgrading to android studio 3.0 you need to go to Build -> Build Apk(s) then copy the apk from build -> output -> apk -> debug

I have also faced the same problem after upgrading android studio to version 3.0! To solve this issue you need to disable instant run that can be found under File -> Settings -> Build,Execution,Deployment -> Instant Run. Now You need to re-generate a signed apk with both the signature versions enabled i.e V1 & V2 that can be found under Build -> Generate Signed APK Now try to install the signed apk, this time it should be installed perfectly :).

first clean your project. delete old apk and json file in debug folder. then re generate build apk. it works.
