Google Maps Signed APK Android

问题

I've got my app that works with google maps in debug mode. I create my signature.jks and then a build my signed APK. I retrieve the SHA1 fingerprint using che command line code

keytool -list -v -keystore signature.jks  -alias myalias -storepass mypass -keypass mypass

and I add this in my project on the google developer console.

But when I run the app on the phone it does not work. It is that the right procedure?

You should setup map key in Android Manifest for all build types (debug release etc.). If you use gradle for building you can customize keys in build.gradle:

buildTypes {

debug {
    debuggable true
    ....
    manifestPlaceholders = [ map_key:"YOUR_DEBUG_cpq5sPasdasdasdAsVIdqK7tfG9xY" ]
}

release {
    debuggable false
    ....
    manifestPlaceholders = [ map_key:"YOUR_RELEASE_4RUFCUrHhZJWpqKGs-d1hOIxELs" ]
}

And in Android Manifest:

<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="${map_key}" />
