This is an Android AdMob plugin for Godot Engine (https://github.com/okamstudio/godot) 3.2.2 or higher. For Godot < 3.2 or iOS support you can use the old module.

Currently, this plugin supports:

• Banner
• Interstitial
• Rewarded Video

• Configure, install and enable the "Android Custom Template" for your project, just follow the official documentation;
• go to the release tab, choose a version and download the respective GodotAdMobPlugin-x.x.x.zip package;
• extract the content of the admob-plugin directory (GodotAdmob.gdap and GodotAdmob.release.aar from the zip package) inside the res://android/plugins directory on your Godot project.
• extract the admob-lib directory (from the zip package) inside the res:// directory on your Godot project.
• on the Project -> Export... -> Android -> Options ->
  • Permissions: check the permissions for Access Network State and Internet
  • Custom Template: check the Use Custom Build
  • Plugins: check the Godot Ad Mob (this plugin)
• edit the file res//android/build/AndroidManifest.xml to add your App ID as described here. For the demo project, for example, you should use:

        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-3940256099942544~3347511713"/>

NOTE: everytime you install a new version of the Android Build Template this step must be done again, as the AndroidManifest.xml file will be overriden.

Now you'll be able to add an AdMob Node to your scene (only one node should be added per scene)

Edit its properties

And connect its signals

In the demo directory you'll find a working sample project where you can see how the things works on the scripting side.

REMEMBER: You still need to configure the project as described in the "How to use" section to be able to run the demo project.

If you want to compile the plugin by yourself, it's very easy:

1. clone this repository;
2. checkout the desired version;
3. using command line go to the admob-plugin directory;
4. run gradlew build.

If everything goes fine, you'll find the .aar files at admob-plugin/godotadmob/build/outputs/aar/.

• First of all, please make sure you're able to compile the custom build for Android without the AdMob plugin, this way we can isolate the cause of the issue.

• Using logcat for Android is the best way to troubleshoot most issues. You can filter Godot only messages with logcat using the command:

adb logcat -s godot

• AdMob Java Singleton not found:

  1. this plugin is Android only, so the AdMob Java singleton will only exists on the Android platform. In other words, you will be able to run it on an Android device (or emulator) only, it will not work on editor or on another platform;
  2. make sure you checked the Use Custom Build and Godot Ad Mob options in the export window.

• Error code 3 (ERROR_CODE_NO_FILL) is a common issue with Admob, but out of the scope to this plugin. Here's the description on the API page: ERROR_CODE_NO_FILL: The ad request was successful, but no ad was returned due to lack of ad inventory.

• Any other error code: you can find more information about the error codes here. Please don't open issues on this repository asking for help about that, as we can't provide any, sorry.

• Banner sizes: this plugin uses Adaptive Banners, you can find more information on how its sizes works on the official AdMob documentation.
