How can deploy signed APK when click Run in Android Studio?

问题

I am developing an app which uses Google APIs. I have created credentials at "Google Developers Console". If I creates a signed APK, and run it on the phone, there is no problem.

The problem is, while I developing the app, when I click RUN button, it deploys an unsigned version of the app on the phone. Thus the application does not work.

How can I set Android Studio to make it deploy signed APK on the phone when click RUN button?

Add these values to your .gradle:

signingConfigs{
    key{
        keyAlias 'your key alias'
        keyPassword 'your keypassword'
        storeFile file('keystore path')
        storePassword 'your storepassword'
    }
}
buildTypes {
    debug{
        signingConfig signingConfigs.key
    }
}

The keystore path in the file will be something like E:/xxx/xxx/xx.keystore.

Usually I do it from command line, installing via "adb install -r file.apk" (-r to preserve app's data)

Also it can be done via Gradle and project settings, see answers here: Android Studio - Run signed apk on emulator

When I want to test my APK release I just use ADB-Link. Its free and very easy to setup. Just make sure to delete any previous builds that you installed on your device otherwise the installation will fail.

Maybe this is not an answer to your question about how to sign the app before running it, but have you thought about the option to create a new signature key for the debug key you are using? You could use a separate API key in debug mode.

I found some extra information about using a key in release and debug mode: Android: automatically choose debug/release Maps v2 api key?
