  • In the Firebase console -> Select your project -> Select Crashlytics -> Setup Crashlytics -> Select that the app is new. (You do not need to download the SDK again as you have already downloaded the Unity plugin)
• Optional: Update the Project Bundle Identifier.
  • If you did not use com.google.firebase.unity.crashlytics.testapp as the Apple bundle ID when creating your app in the Firebase Console, you will need to update the sample's Bundle Identifier.
    • Select the File > Build Settings menu option.
    • Select iOS or tvOS in the Platform list, depending on your build target.
    • Click Player Settings.
    • In the Settings for iOS or Settings for tvOS panel, scroll down to Bundle Identifier and update the value to the Apple bundle ID you provided when you registered your app with Firebase.

      • If you do not use the prescribed package name, you will need to update the bundle identifier as described in Optional: Update the Project Bundle Identifier below.
  • Android apps must be signed by a key, and the key's signature must be registered to your project in the Firebase Console. To generate a SHA1, first you will need to set the keystore in the Unity project.
    • Locate the Publishing Settings under Player Settings in the Unity editor.
    • Select an existing keystore, or create a new keystore using the toggle.
    • Select an existing key, or create a new key using Create a new key.
    • After setting the keystore and key, you can generate a SHA1 by running this command:

    • Copy the SHA1 digest string into your clipboard.
    • Navigate to your Android App in your firebase console.
      • From the main console view, click on your Android App at the top and click the gear to open the settings page.
      • Scroll down to your apps at the bottom of the page and click on Add Fingerprint.
    • Paste the SHA1 digest of your key into the form. The SHA1 box will illuminate if the string is valid. If it's not valid, check that you have copied the entire SHA1 digest string.

This testapp was designed for use on iOS and Android targets, and when running in the Unity editor. While the code will also execute on tvOS, the buttons will be unresponsive as there isn't an easy way to provide the app with the click / touch events to orchestrate the UI elements on that platform.

Note: the UI elements of the quickstart app respond only to mouse clicks, and so will not be responsive on tvOS.

• Once the Unity test app is running (detach debugger if attached), click the Perform All Actions button.
• Trigger upload by completely closing and relaunching the test app.
• To view the reported issues, go to the Firebase Crashlytics console for the test app.
  • Add a time filter to more easily identify the errors if needed

• When upgrading to a new Firebase release: import the new firebase unity package through Assets > Import Package > Custom Package as above. After the import is complete you may need to run the Assets > Play Services Resolver for the changes to be reflected in the editor. If issues persist, delete the plugin and install it again.
• Android: After exiting the editor and returning you will need to reconfigure the Project Keystore in Player Settings > Publishing Settings. Select your Custom Keystore from the dropdown list and enter its password. Then, select your Project Key alias and enter your key's password.
• Please see the Known Issues section of the Unity Setup Guide for other troubleshooting topics.
• When running the app, if all that you see is a blue horizon, then please ensure that you followed the steps to Open the scene MainScene above.
