Question

when I try to generate the release version using the following command:

cd android & &. / gradlew assembleRelease

apk file is created in the directory:

/app/build/outputs/apk/app-release-unsigned.apk

Unfortunately, when I try to install apk on my Android 5. phone, I received the following error:

The problem was package analysis.

Note that I am using the native reaction under windows.
