Issue with bundling Android Wear1 app's with android gradle plugin 3.0.1

Question

I cannot get the Wear1 signed APK into the res/raw folder of my signed mobile apk file since using the latest android gradle plugin 3.0.1

I have to use the latest gradle to get the google repo for certain dependencies.

I have checked the wear apk and it is signed with my production signature.

I know the preferred method going forward is to unbundle and I can successfully do that but Google's acknowledged latency issue on installing Wear 1 apps that way makes it unattractive at this time.

Below are my gradle files.

Project build.config

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

    repositories {

Answer 1

I was having the same problem this week. Today I finally managed to get the wear app correctly embedded into the mobile app APK using the 3.0.1 gradle. I added a productFlavor to my wear app build.gradle to match the productFlavor of the mobile app that I was generating the build for. Trying to specify a differently-named wear app configuration in the mobile app's build.gradle dependency list seemed to be the problem for me.

I would suggest trying to add development and production flavors to your wear app build.gradle:

development {
                dimension "wearVersion"
                // Use the defaultConfig value
            }

production {
                dimension "wearVersion"
                // Use the defaultConfig value
            }

and then change your mobile app build.gradle dependency to simply:

wearApp project(path: ':wear')

When you generate the build, it should match productFlavor to productFlavor by default and that is working for me.
