If your app needs to collect\nadditional data, you can set up to 25 different Analytics user properties\nand log up to 500 different Analytics event *types* in your app.\nThere is no limit on the total volume of events your app logs.\n\nTo access this data:\n\n1. In the [Firebase console](//console.firebase.google.com/), open your project.\n2. Select **Analytics** from the menu to view the Analytics reporting dashboard.\n\nThe **Events** tab shows the event reports that are\nautomatically created for each distinct type of Analytics event logged by\nyour app. Read more about the [dashboard](https://support.google.com/analytics/answer/11014767).\n\nTo help you get started, the Analytics SDK defines a number of\nrecommended events that are common among different types of apps, including\nretail and ecommerce, travel, and gaming apps. To learn more about these events\nand when to use them, see [Recommended events](https://support.google.com/analytics/answer/9267735).\nTo get the maximum detail in reports, log\nthe recommended events that make sense for your app and their\nprescribed parameters. This also ensures that you benefit from the latest\nGoogle Analytics features as they become available.\n\nBefore you begin\n\nBefore you can use\n[Google Analytics](/docs/reference/unity/namespace/firebase/analytics),\nyou need to:\n\n- Register your C++ project and configure it to use Firebase.\n\n If your C++ project already uses Firebase, then it's already registered and\n configured for Firebase.\n- Add the [Firebase C++ SDK](/download/cpp) to your C++ project.\n\n| **Find detailed instructions for these initial\n| setup tasks in\n| [Add Firebase to your C++\n| project](/docs/cpp/setup#note-select-platform).**\n\nNote that adding Firebase to your C++ project involves tasks both in the\n[Firebase console](//console.firebase.google.com/) and in your open C++ project (for example, you download\nFirebase config files from the console, then move them into your C++ project).\n\nCreate and initialize the firebase app\n\nBefore you start, you'll need to create and initialize the firebase App: \n\nAndroid\n\nCreate the firebase app, passing the jni environment and a `jobject`\nreference to the java activity as arguments: \n\n```c++\napp = ::firebase::App::Create(::firebase::AppOptions(), jni_env, activity);\n```\n\nInitialize the Analytics library: \n\n```c++\n::firebase::analytics::Initialize(app);\n```\n\n\u003cbr /\u003e\n\niOS+\n\nCreate the firebase app: \n\n```c++\napp = ::firebase::App::Create(::firebase::AppOptions());\n```\n\nInitialize the Analytics library: \n\n```c++\n::firebase::analytics::Initialize(app);\n```\n\n\u003cbr /\u003e\n\nLog events\n\nAfter you have configured the [`firebase::App`](/docs/reference/cpp/class/firebase/app) instance, you can\nbegin to log events with the [`LogEvent()`](/docs/reference/cpp/namespace/firebase/analytics#logevent) method.\n\nThe following example updates the user's score: \n\n```c++\nanalytics::LogEvent(analytics::kEventPostScore, analytics::kParameterScore, 42);\n```\n| **Note:** Once the property is registered, it can take up to 24 hours for data collected with the property to be included in reports. When the new data is available, the user property can be used as a report filter.\n\nNext steps\n\n- See your data refresh periodically in the [Firebase console](//console.firebase.google.com/).\n- Explore the guides on [events](/docs/analytics/cpp/events) and [user properties](/docs/analytics/cpp/properties)."]]
