How to sign automatically when I click RUN button in Android Studio?

When I'm developing, always use Run(Shif+F10) button. But Run makes unsigned application. So if I want to test my app, i must do Build > Generate Signed APK > install. It's very annoying. So I want to sign automatically when I click Run button.

If it's impossible, please tell me useful function for testing my app

Solution

Yes, it's possible use following code add into your Gradle script.

I managed to solve it adding this code, and building with gradle build:

android {
...
signingConfigs {
    release {
        storeFile file("release.keystore")
        storePassword "******"
        keyAlias "******"
        keyPassword "******"
    }
}
buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}

}

This generates a signed release apk file. Also while generate your api please ensure that your buid veriant is Relese like this.
