The Firebase Google Mobile Ads Test Application (testapp) demonstrates loading and showing AdMob-served banners, interstitials and rewarded ads using the Firebase GMA C++ SDK. The application has no user interface and simply logs actions it's performing to the console while displaying the ads.

• Read more about Firebase GMA

• Link your iOS app to the Firebase libraries.
  • Get CocoaPods version 1 or later by running,

    sudo gem install cocoapods --pre
    

  • From the testapp directory, install the CocoaPods listed in the Podfile by running,

    pod install
    

  • Open the generated Xcode workspace (which now has the CocoaPods),

    open testapp.xcworkspace
    

  • For further details please refer to the general instructions for setting up an iOS app with Firebase.
• Register your iOS app with Firebase.
  • Create a new app on the Firebase console, and attach your iOS app to it.
    • You can use "com.google.ios.admob.testapp" as the iOS Bundle ID while you're testing. You can omit App Store ID while testing.
• Download the Firebase C++ SDK linked from https://firebase.google.com/docs/cpp/setup and unzip it to a directory of your choice.
• Add the following frameworks from the Firebase C++ SDK to the project:
  • frameworks/ios/universal/firebase.framework
  • frameworks/ios/universal/firebase_gma.framework
  • You will need to either,
    1. Check "Copy items if needed" when adding the frameworks, or
    2. Add the framework path in "Framework Search Paths"
       • For example, if you downloaded the Firebase C++ SDK to /Users/me/firebase_cpp_sdk, then you would add the path /Users/me/firebase_cpp_sdk/frameworks/ios/universal.
       • To add the path, in Xcode, select your project in the project navigator, then select your target in the main window. Select the "Build Settings" tab, and click "All" to see all the build settings. Scroll down to "Search Paths", and add your path to "Framework Search Paths".
• Update the AdMob App ID:
  • In the testapp/Info.plist, update GADApplicationIdentifier with the app ID for your iOS app, replacing 'YOUR_IOS_ADMOB_APP_ID'.
  • For more information, see Update your Info.plist
• In Xcode, build & run the sample on an iOS device or simulator.
• The testapp displays a banner ad, an interstitial ad and a rewarded ad. You must dismiss each ad to see the next.
• The output of the app can be viewed onscreen or via the console. To view the console in Xcode, select "View --> Debug Area --> Activate Console" from the menu.

• Register your Android app with Firebase.
  • Create a new app on the Firebase console, and attach your Android app to it.
    • You can use "com.google.android.admob.testapp" as the Package Name while you're testing.
    • To generate a SHA1 run this command on Mac and Linux,

      keytool -exportcert -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore
      

      or this command on Windows,

      keytool -exportcert -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore
      

    • If keytool reports that you do not have a debug.keystore, you can create one with,

      keytool -genkey -v -keystore ~/.android/debug.keystore -storepass android -alias androiddebugkey -keypass android -dname "CN=Android Debug,O=Android,C=US"
      

  • Add the google-services.json file that you downloaded from Firebase console to the root directory of testapp. This file identifies your Android app to the Firebase backend.
  • For further details please refer to the general instructions for setting up an Android app with Firebase.
• Download the Firebase C++ SDK linked from https://firebase.google.com/docs/cpp/setup and unzip it to a directory of your choice.
• Configure the location of the Firebase C++ SDK by setting the firebase_cpp_sdk.dir Gradle property to the SDK install directory. For example, in the project directory:

  echo "systemProp.firebase\_cpp\_sdk.dir=/User/$USER/firebase\_cpp\_sdk" >> gradle.properties
  

• Ensure the Android SDK and NDK locations are set in Android Studio.
  • From the Android Studio launch menu, go to File/Project Structure... or Configure/Project Defaults/Project Structure... (Shortcut: Control + Alt + Shift + S on windows, Command + ";" on a mac) and download the SDK and NDK if the locations are not yet set.
• Open build.gradle in Android Studio.
  • From the Android Studio launch menu, "Open an existing Android Studio project", and select build.gradle.
• Install the SDK Platforms that Android Studio reports missing.
• Update the GMA App ID:
  • In the AndroidManifest.xml, update com.google.android.gms.ads.APPLICATION_ID with the same app ID, replacing 'YOUR_ANDROID_ADMOB_APP_ID'.
  • For more information, see Update your AndroidManifest.xml
• Build the testapp and run it on an Android device or emulator.
• The testapp will initialize the GMA SDK, then load and display a test banner ad, interstitial ad and rewarded ad.
• Tapping on an ad to verify the clickthrough process is possible, and the test app will wait for each ad to be dismissed.
• While this is happening, information from the device log will be written to an onscreen TextView.
  • Logcat can also be used as normal.

• Note: the testapp has no user interface, but the output can be viewed via the console. The GMA SDK uses a stubbed implementation on desktop, so functionality is not expected, and the app will end waiting for the interstitial ad to be dismissed.
• Register your app with Firebase.
  • Create a new app on the Firebase console, following the above instructions for Android or iOS.
  • If you have an Android project, add the google-services.json file that you downloaded from the Firebase console to the root directory of the testapp.
  • If you have an iOS project, and don't wish to use an Android project, you can use the Python script generate_xml_from_google_services_json.py --plist, located in the Firebase C++ SDK, to convert your GoogleService-Info.plist file into a google-services-desktop.json file, which can then be placed in the root directory of the testapp.
• Download the Firebase C++ SDK linked from https://firebase.google.com/docs/cpp/setup and unzip it to a directory of your choice.
• Configure the testapp with the location of the Firebase C++ SDK. This can be done a couple different ways:
  • When invoking cmake, pass in the location with -DFIREBASE_CPP_SDK_DIR=/path/to/firebase_cpp_sdk.
  • Set an environment variable for FIREBASE_CPP_SDK_DIR to the path to use.
  • Edit the CMakeLists.txt file, changing the FIREBASE_CPP_SDK_DIR path to the appropriate location.
• From the testapp directory, generate the build files by running,

  cmake .
  

  If you want to use XCode, you can use -G"Xcode" to generate the project. Similarly, to use Visual Studio, -G"Visual Studio 15 2017". For more information, see CMake generators.
• Build the testapp, by either opening the generated project file based on the platform, or running,

  cmake --build .
  

• Execute the testapp by running,

  ./desktop_testapp
  

  Note that the executable might be under another directory, such as Debug.
