Continued use of this signal was restricted to customers with existing implementations, through October 30, 2019. New implementations must use the [Places SDK for Android](/places/android-sdk) instead of the Places contextual signal.\n| - The Weather contextual signal has also been turned off. Continued use of this signal has been restricted to customers with existing implementations, through January 31, 2020. Google doesn't offer alternative functionality for the Weather contextual signal.\n\nYou can use the [Snapshot API](/android/reference/com/google/android/gms/awareness/Awareness#getSnapshotClient(android.app.Activity))\nto get information about the user's current environment. With the Snapshot API,\nyou can access a variety of [context signals](/awareness/overview#context-types):\n\n- Detected user activity, such as when they walk or drive.\n- Nearby beacons that you've registered.\n- Headphone state, plugged in or not.\n- Location, which includes latitude and longitude.\n\nThe system caches these values so that they can be returned quickly. If there's\nno data, sensing and inference are performed to return fresh state values.\nThe Awareness API returns the existing data type for context types that have a\npublic API.\n\nEach context signal has a corresponding Snapshot API method. For example, to\nget the current detected activity, you call\n[`getDetectedActivity()`](/android/reference/com/google/android/gms/awareness/SnapshotClient#getDetectedActivity()),\nuse a `SuccessListener` to get a [`DetectedActivityResponse`](/android/reference/com/google/android/gms/awareness/snapshot/DetectedActivityResponse),\nthen call [`getActivityRecognitionResult()`](/android/reference/com/google/android/gms/awareness/snapshot/DetectedActivityResponse#getActivityRecognitionResult())\nto return an [`ActivityRecognitionResult`](/android/reference/com/google/android/gms/location/ActivityRecognitionResult)\nfrom which you can get the actual request data.\n\nThe following example shows how to get the latest detected activity: \n\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 }\n })\n\nFor more information about what you can do with the request data, see\n[Get Snapshot data](/awareness/android-api/snapshot-get-data)."]]
