Tài liệu này giải thích cách bắt đầu phát triển bằng Awareness API trên Android. Awareness API là một phần của Dịch vụ Google Play.
Để sử dụng Awareness API, bạn cần có Tài khoản Google.
Nếu đã có tài khoản thì bạn có thể bỏ qua bước này. Bạn cũng nên có một Tài khoản Google riêng cho mục đích thử nghiệm.
Trước khi bắt đầu
Lấy khoá API
Nếu bạn chưa bật Awareness API và chưa lấy khoá API của Google, hãy làm theo các bước trong phần Đăng ký và khoá API để thực hiện.
Định cấu hình ứng dụng
Trong tệp build.gradle cấp dự án, hãy thêm kho lưu trữ Maven của Google vào cả hai mục buildscript và allprojects:
Thêm Khoá API Awareness vào tệp AndroidManifest.xml của ứng dụng. Để làm như vậy, hãy thêm thẻ <meta-data> bằng android:name="com.google.android.awareness.API_KEY". Đối với android:value, hãy chèn Khoá API Nhận biết của riêng bạn trong dấu ngoặc kép.
Thêm các quyền cần thiết vào tệp AndroidManifest.xml của ứng dụng. Các quyền bắt buộc sẽ khác nhau, tuỳ thuộc vào phương thức API và loại hàng rào mà ứng dụng của bạn sử dụng.

The `getDetectedActivity()` example shows how to retrieve the user's current activity.\n"],null,["# Get started\n\nThis document explains how to start to develop with the Awareness API on\nAndroid. The Awareness API is part of [Google Play services](/android/guides/overview).\n\nTo use the Awareness API, you need a [Google Account](//www.google.com/accounts/NewAccount).\nIf you already have an account, then you're all set. You might also want a\nseparate Google Account for testing purposes.\n\nBefore you begin\n----------------\n\n### Obtain an API key\n\nIf you haven't already enabled the Awareness API and obtained a Google API key,\nfollow the steps in [Signup and API keys](/awareness/android-api/get-a-key)\nto do so.\n\n### Configure your app\n\n1. In your project-level `build.gradle` file, include Google's Maven repository\n in both your `buildscript` and `allprojects` sections:\n\n buildscript {\n repositories {\n google()\n }\n }\n\n allprojects {\n repositories {\n google()\n }\n }\n\n2. Add the dependencies for the Awareness API to your module's app-level\n Gradle file, which is usually `app/build.gradle`:\n\n dependencies {\n implementation 'com.google.android.gms:play-services-awareness:19.1.0'\n }\n\n3. Add your Awareness API Key to your app's `AndroidManifest.xml` file. To do\n so, add a `\u003cmeta-data\u003e` tag with\n `android:name=\"com.google.android.awareness.API_KEY\"`. For `android:value`,\n insert your own Awareness API Key, surrounded by quotation marks.\n\n ```xml\n \u003cmanifest\u003e\n \u003capplication\u003e\n \u003cmeta-data\n android:name=\"com.google.android.awareness.API_KEY\"\n android:value=\"\u003cvar translate=\"no\"\u003eAPI_KEY\u003c/var\u003e\"/\u003e\n \u003c/application\u003e\n \u003c/manifest\u003e\n ```\n4. Add the necessary permissions to your app's `AndroidManifest.xml` file. The\n required permissions vary, depending on the API methods and fence types that\n your app uses.\n\nExample call\n------------\n\nThe following example call to\n[`getDetectedActivity()`](/android/reference/com/google/android/gms/awareness/SnapshotClient#getDetectedActivity())\ndemonstrates how to use the connectionless Google Play services model with the\nAwareness API: \n\n // Each type of contextual information in the snapshot API has a corresponding \"get\" method.\n // For instance, this is how to get the user's current Activity.\n Awareness.getSnapshotClient(this).getDetectedActivity()\n .addOnSuccessListener(new OnSuccessListener\u003cDetectedActivityResponse\u003e() {\n @Override\n public void onSuccess(DetectedActivityResponse dar) {\n ActivityRecognitionResult arr = dar.getActivityRecognitionResult();\n // getMostProbableActivity() is good enough for basic Activity detection.\n // To work within a threshold of confidence,\n // use ActivityRecognitionResult.getProbableActivities() to get a list of\n // potential current activities, and check the confidence of each one.\n DetectedActivity probableActivity = arr.getMostProbableActivity();\n\n int confidence = probableActivity.getConfidence();\n String activityStr = probableActivity.toString();\n mLogFragment.getLogView().println(\"Activity: \" + activityStr\n + \", Confidence: \" + confidence + \"/100\");\n }\n })\n\nNext steps\n----------\n\nLearn more about the different APIs within the Awareness API:\n\n- [Snapshot API guide](/awareness/android-api/snapshot-api-overview) and [Snapshot API reference](/android/reference/com/google/android/gms/awareness/snapshot/package-summary).\n- [Fence API guide](/awareness/android-api/fence-api-overview) and [Fence API\n reference](/android/reference/com/google/android/gms/awareness/fence/package-summary)."]]
