Gradle

Using AndroidX

  • Add the terms of use for AndroidX to build settings.

    • Android Studio

      # gradle.properties
# >>> [AndroidX]
android.useAndroidX=true
android.enableJetifier=true

    • Unity 2019.2 or earlier

      // mainTemplate.gradle
([rootProject] + (rootProject.subprojects as List)).each {
    ext {
        // >>> [AndroidX]
        it.setProperty("android.useAndroidX", true)
        it.setProperty("android.enableJetifier", true)
    }
}

    • Unity 2019.3 or later

      # gradleTemplate.properties
# >>> [AndroidX]
android.useAndroidX=true
android.enableJetifier=true

    • Unreal

      <gradleProperties>
  <insert>
    android.useAndroidX=true
    android.enableJetifier=true
  </insert>
</gradleProperties>

Under AGP 3.4.0

  • If the Android Gradle Plugin version is lower than 3.4.0, the build will fail, so the following declaration is required:

    # gradle.properties
# >>> Fix for AGP under 3.4.0
android.enableD8.desugaring=true
android.enableIncrementalDesugaring=false

  • For Unity, the following declaration is required if the Editor version is 2018.4.3 or lower or 2019.1.6 or lower. (AGP version is 3.2.0)

    // mainTemplate.gradle
([rootProject] + (rootProject.subprojects as List)).each {
    ext {
        // >>> Fix for AGP under 3.4.0
        it.setProperty("android.enableD8.desugaring", true)
        it.setProperty("android.enableIncrementalDesugaring", false)
    }
}

Define Adapters

  • Declare Gamebase version and authentication to use, and the payment and the push modules in the build.gradle file. 
repositories {
    // >>> For Gamebase SDK
    mavenCentral()
    ...

    // >>> [Huawei App Gallery]

Resources

Huawei Store

  • You must add the AppGallery Connection configuration file (agconnect-service.json) to the assets folder.
    • Log in to AppGallery Connect and click on My Projects.
    • Select an app from your project.
    • Go to Project settings > General information.
    • Download the agconnect-service.json file from App information.
    • For Android Studio builds
      • Copy the agconnect-service.json file to the assets folder in your project.
    • For Unity builds
      • Copy the agconnect-service.json file to the Assets/StreamingAssets folder in your project.

Firebase Notification

  • For Android Studio build

  • For a Unity build

    • If the Firebase Unity SDK Package has been installed, you can use the following command to execute generate_xml_from_google_services_json.exe file to convert json files into xml files.

      "{UnityProject}\Firebase\Editor\generate_xml_from_google_services_json.exe" -i "{JsonFilePath}\google-services.json" -o "{UnityProject}\Assets\Plugins\Android\res\values\google-services.xml" -p "{PackageName}"

    • If the Firebase Unity SDK Package is not installed, go to 'Firebase Console > Project Settings' to download google-services.json file, and then follow the guide below to directly create a string resource (xml) file. The created file must be included in 'Assets/Plugins/Android/res/values/' folder. Depending on the Firebase service link, the contents of the google-services.json file may vary. Download google-services.json

<!-- Assets/Plugins/Android/res/values/google-services-json.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="firebase_database_url" translatable="false">https://gamebase-sample-00000000.firebaseio.com</string>
    <string name="gcm_defaultSenderId" translatable="false">000000000000</string>
    <string name="google_storage_bucket" translatable="false">gamebase-sample-00000000.appspot.com</string>
    <string name="project_id" translatable="false">gamebase-sample-00000000</string>
    <string name="google_api_key" translatable="false">AbCd_AbCd_AbCd_AbCd_AbCd_AbCd_AbCd</string>
    <string name="google_app_id" translatable="false">1:000000000000:android:abcd0123abcd0123</string>
    <string name="default_web_client_id" translatable="false">000000000000-abcdabcdabcdabcdabcdabcdabcd.apps.googleusercontent.com</string>
</resources>
  • In the case of Unreal build, it is distributed by Gamebase Unreal SDK which included empty google-service-json.xml files, so please change it to the appropriate value for the game information.
    • If there is Content automatically creating xml in a similar form like EasyFirebase, there may be a build error due to resource duplication. At this time, remove the google-service-json.xml file.

AndroidManifest.xml

Facebook IdP

  • Declares App ID to initialize Facebook SDK.
    • It is better to configure so that the value refers to resources rather than directly declaring it.
    • This setting is not required at the moment as Gamebase SDK internally calls a function to initialize Facebook SDK.

AndroidManifest.xml

<manifest ...>
    <application ...>
        ...
        <!-- [Facebook] Configurations begin -->
        <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id" />
        <!-- [Facebook] Configurations end -->
        ...
    </application>
</manifest>

res/values/strings.xml

<resources>
    <!-- [Facebook] Facebook APP ID -->
    <string name="facebook_app_id">123456789012345</string>
</resources>

LINE IdP

  • As android:allowBackup="false" is declared in LINE SDK, Manifest merger might fail while building the application. If a build fails in this way, add tools:replace="android:allowBackup" declaration to the application tag.
<application
      tools:replace="android:allowBackup"
      ... >

Weibo IdP

  • In order for Weibo IdP to work properly, android:networkSecurityConfig attribute must be added to application tag, and the name of the xml file which has declared the weibo/sina-related URL must be set.
<application android:networkSecurityConfig="@xml/my_network_security_config"
    ...>
    ...
</application>
  • res/xml/my_network_security_config.xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <!-- Weibo SDK start -->
        <domain includeSubdomains="true">sina.cn</domain>
        <domain includeSubdomains="true">weibo.cn</domain>
        <domain includeSubdomains="true">weibo.com</domain>
        <domain includeSubdomains="true">sinaimg.cn</domain>
        <domain includeSubdomains="true">sinajs.cn</domain>
        <domain includeSubdomains="true">sina.com.cn</domain>
        <!-- Weibo SDK end -->
    </domain-config>
</network-security-config>

ONE Store

  • ONE store supports both full payment screen and payment popup window.
    • You can add AndroidManifest.xml to meta-data to select the full payment screen ("full") or payment popup window ("popup") screen.
    • If meta-data is not set, the default ("full") is applied.
<manifest>
    ...
    <application>
        ...
        <!-- [ONE store] Configurations begin -->
        <!-- popup:payment popup window / full:full payment screen -->
        <meta-data
            android:name="iap:view_option"
            android:value="popup | full" />
        <!-- [ONE store] Configurations end -->
        ...
    </application>
</manifest>
Payment screen Set value
Full payment screen "full"
Payment popup window "popup"

Notification Options

  • You can use the following method to set the notification option:

Example

<!-- When you have multiple applications sharing an Gamebase project, use this field to identify each application. -->
<meta-data android:name="com.nhncloud.sdk.push.deviceId.salt"
           android:value="ApplicationForGoogleStore" />

<!-- Notification priority -->
<meta-data android:name="com.toast.sdk.push.notification.default_priority"
           android:value="1"/>
<!-- Notification background color -->
<meta-data android:name="com.toast.sdk.push.notification.default_background_color"
           android:resource="@color/defaultNotificationColor"/>
<!-- LED light -->
<meta-data android:name="com.toast.sdk.push.notification.default_light_color"
           android:value="#0000ff"/>
<meta-data android:name="com.toast.sdk.push.notification.default_light_on_ms"
           android:value="0"/>
<meta-data android:name="com.toast.sdk.push.notification.default_light_off_ms"
           android:value="500"/>
<!-- Small icon -->
<meta-data android:name="com.toast.sdk.push.notification.default_small_icon"
           android:resource="@drawable/ic_notification"/>
<!-- Sound -->
<meta-data android:name="com.toast.sdk.push.notification.default_sound"
           android:value="notification_sound"/>
<!-- Vibrate pattern -->
<meta-data android:name="com.toast.sdk.push.notification.default_vibrate_pattern"
           android:resource="@array/default_vibrate_pattern"/>
<!-- Use badge icon or not -->
<meta-data android:name="com.toast.sdk.push.notification.badge_enabled"
           android:value="true"/>
<!-- Enable notification when application is foreground. -->
<meta-data android:name="com.toast.sdk.push.notification.foreground_enabled"
           android:value="false"/>
