The Firebase Auth Test Application (testapp) demonstrates authentication and user profile operations with the Firebase Auth C++ SDK. The application has no user interface and simply logs actions it's performing to the console.

The testapp performs the following:

• Creates a firebase::App in a platform-specific way. The App holds platform-specific context that's used by other Firebase APIs.
• Gets a pointer to firebase::Auth. The Auth class is the gateway to all Firebase Authentication functionality.
• Calls every member function on firebase::Auth. Many of these functions are asynchronous, since they communicate with a server. Asynchronous functions return a firebase::Future class, which we wait on until the call completes. In practice, you will probably want to register a callback on the Future, or poll it periodically instead of waiting for it to complete.
• Gets a pointer to firebase::User. The User class allows account manipulation and linking. It's returned by every Auth sign-in operation, and the currently active User is available via Auth::CurrentUser(). Only one User can be active at a time.
• Calls every member function on firebase::User.

• 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.auth.testapp" as the iOS Bundle ID while you're testing. You can omit App Store ID while testing.
  • Add the GoogleService-Info.plist that you downloaded from Firebase console to the testapp root directory. This file identifies your iOS app to the Firebase backend.
  • In Firebase console, select "Auth", then enable "Email/Password", and also enable "Anonymous". This will allow the testapp to use email accounts and anonymous sign-in.
• 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_auth.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"
       • e.g. 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".
• In XCode, build & run the sample on an iOS device or simulator.
• The testapp has no user interface. The output of the app can be viewed via the console. In Xcode, select "View --> Debug Area --> Activate Console" from the menu.
• See below for usage instructions.

• 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.auth.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.
  • In Firebase console, select "Auth", then enable "Email/Password", and also enable "Anonymous". This will allow the testapp to use email accounts and anonymous sign-in.
  • 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 Configure/Project Defaults/Project Structure 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.
• Build the testapp and run it on an Android device or emulator.
• The testapp has no user interface. The output of the app can be viewed in the logcat output of Android studio or by running "adb logcat *:W android_main firebase" from the command line.

• Auth::SignInAnonymously() and Auth::CreateUserWithEmailAndPassword() are temporarily broken. For the moment, they will always return kAuthError_GeneralBackendError.
• User::UpdateUserProfile() currently fails to set the photo URL on both Android and iOS, and also fails to set the display name on Android.
• The iOS testapp generates benign asserts of the form: assertion failed: 15D21 13C75: assertiond + 12188 [8CF1968D-3466-38B7-B225-3F6F5B64C552]: 0x1
• Several API function are pending competion and will return status firebase::kAuthError_Unimplemented or empty data.
  • Auth::ConfirmPasswordReset()
  • Auth::CheckActionCode()
  • Auth::ApplyActionCode()
  • User::Reauthenticate()
  • User::SendEmailVerification()
  • User::Delete()
  • User::ProviderData()
• Several API functions return different error codes on iOS and Android. The disparities will be eliminated in a subsequent release.
• When given invalid parameters, several API functions return kAuthError_GeneralBackendError instead of kAuthError_InvalidEmail or kAuthError_EmailNotFound.
