Upload failed: Your Instant App APKs should contain at least one base APK

Question

I need to prepare an Alpha testing for an Instant App and It run like a charm on Android Studio but It is failing when I try to upload it to the PlayStore, saying:

Upload failed

Your Instant App APKs should contain at least one base APK.

The app structure is done using three modules:

-base: It contains all the code

-apk: Wrapper to obtains the installable apk

-instantApp: Wrapper to obtain the instantApp apk

This are the build.gradles:

base/build.gradle

buildscript {
    repositories {
        jcenter()
    }
}
apply plugin: 'com.android.feature'

repositories {
    jcenter()
    mavenCentral()
    flatDir {
        dirs 'libs'
    }
    maven { url 'https://maven.fabric.io/public' }
}

android {
    compileSdkVersion 25
    buildToolsVersion "26.0.0-rc2"

    baseFeature = true
    dataBinding {
        enabled = true
    }

    defaultConfig {

        minSdkVersion 18
        targetSdkVersion 25
        versionCode 7
        versionName "1.1"
    }

    signingConfigs {
        release {
            [...]
        }
    }

    buildTypes {
        debug {
            [...]
        }
        release {
            minifyEnabled false
            signingConfig signingConfigs.release
            [...]
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    lintOptions {
        abortOnError false
    }

    dexOptions {
        javaMaxHeapSize "4g"
    }
}

dependencies {

    application project(":apk")
    [...]
}
apply plugin: 'com.google.gms.google-services'

apk/build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "26.0.0-rc2"

    dataBinding {
        enabled true
    }

    defaultConfig {
        applicationId “…”
        minSdkVersion 18
        targetSdkVersion 25
        versionCode 7
       versionName "1.1"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    signingConfigs {
        release {
            [...]
        }
    }

    buildTypes {
        debug {
            […]
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            signingConfig signingConfigs.release
            […]
        }
    }
}

dependencies {
    implementation project(':base')
}

instantApp/build.gradle

apply plugin: 'com.android.instantapp'

dependencies {
    implementation project(':base')
}

And this are the Manifests files

base/Manifest.xml

        </intent-filter>
    </receiver>

    <meta-data
        android:name="com.parse.push.gcm_sender_id"

</application>
</manifest>

apk/Manifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

This package is different that the app's one

I already tried this solution: (Android Instant-release build not includes base APK) but it didn't work.

I m stuck since the last Friday so any kind of idea could be awesome

Thanks in advance

P.D: Its my first question so I m sorry if I didn't do it propertly ;)

Answer 1

Yeah!!! I found the issue!!!!(and its not in any of the google help documents)

The issue was that I was dropping the instantApp apk file straight away. The solution is to create a zip file with the instantApp apk and the base apk and drop that zip file!!!

Thanks for your help!!! At the end the issue wasnt gradle or the code..it was the PlayStore :)

I hope that if anyone has the same problem this question can help them!!!

Answer 2

This sample project seems to be pretty close to what you're trying to achieve. Perhaps you don't need the application project(":apk") in your base/build.gradle since you only have one feature (and that is the base split). You could also try removing base = true.

This section of the docs covers your use case - but it sounds like everything is set up correctly.

Could you also add your AndroidManifests to your original post?
