Generate Signed APK in Android Studio

Question

There are a few questions related to my question in Stackoverflow, such as:

How do I export a project in the Android studio?

How to create a release signed apk file using Gradle

They're good. But Still make me confused. When I selected Build->Generate signed APK in Android Studio, I got this warning message:

What does this mean? Does it mean I have to use gradle command line by config the build.gradle? Then what is the wizard for? If I just ignore the warning by click ok and follow the wizard to generate the apk file, I'll get error message saying the apk is in debug mode when I upload the apk to Google Play.

If I follow the instruction to setup the build.gradle like this:

 signingConfigs {

        debug {
            storeFile file("debug.keystore")
        }

        release {
            storeFile file("../key/test.keystore")
            storePassword "password"
            keyAlias "key"
            keyPassword "password"
        }
    }

    buildTypes {
        release {
            debuggable false
            signingConfig signingConfigs.release
        }
    }

And everything is file when I run ./gradlew assembleRelease in terminal.

In summary, I'm confused at:

1. What is the purpose of "Generate signed APK" wizard if I have to setup the build.gradle
2. How to build my application in release mode when I run "Generate signed APK"

Thank you for any suggestion.

In left bottom corner of Android Studio, select the Build Variances, then you can change the build mode to "release". When building in release mode, I think the "Generate Signed APK" wizard works. So just ignore the build.gradle configuration!
