Fence API 가 지정된 상태를 계속 확인하는 동안 Snapshot API 는 현재 상태를 요청하는 데 사용되며 앱이 실행되지 않을 때 콜백을 전송합니다.
전반적으로 Snapshot API 또는 Fence API를 사용하기위한 몇 가지 기본 단계가 있습니다.
Google Developers Console 에서 API 키 가져 오기
매니페스트에 필요한 권한 및 API 키를 추가합니다.
<!-- Not required for getting current headphone state --> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <!-- Only required for actvity recognition --> <uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION"/> <!-- Replace with your actual API key from console --> <meta-data android:name="com.google.android.awareness.API_KEY" android:value="YOUR_API_KEY"/> <!-- Required for Snapshot API only --> <meta-data android:name="com.google.android.geo.API_KEY" android:value="YOUR_API_KEY"/>
가능하면 활동의 onCreate () 메소드에서
GoogleApiClient
어딘가에 초기화하십시오.GoogleApiClient client = new GoogleApiClient.Builder(context) .addApi(Awareness.API) .build(); client.connect();
원하는 API를 호출하십시오.
구문 분석 결과
필요한 사용자 권한을 확인하는 쉬운 방법은 다음과 같은 방법입니다.
private boolean isFineLocationGranted() {
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
Log.e(getClass().getSimpleName(), "Fine location permission not granted!");
}
}
Snapshot API를 사용하여 현재 사용자 활동 가져 오기
사용자의 신체 활동에 대한 일시적이지 않은 요청의 경우 Snapshot API를 사용하십시오.
// Remember to initialize your client as described in the Remarks section
Awareness.SnapshotApi.getDetectedActivity(client)
.setResultCallback(new ResultCallback<DetectedActivityResult>() {
@Override
public void onResult(@NonNull DetectedActivityResult detectedActivityResult) {
if (!detectedActivityResult.getStatus().isSuccess()) {
Log.e(getClass().getSimpleName(), "Could not get the current activity.");
return;
}
ActivityRecognitionResult result = detectedActivityResult
.getActivityRecognitionResult();
DetectedActivity probableActivity = result.getMostProbableActivity();
Log.i(getClass().getSimpleName(), "Activity received : " +
probableActivity.toString());
}
});
Snapshot API로 헤드폰 상태 가져 오기
// Remember to initialize your client as described in the Remarks section
Awareness.SnapshotApi.getHeadphoneState(client)
.setResultCallback(new ResultCallback<HeadphoneStateResult>() {
@Override
public void onResult(@NonNull HeadphoneStateResult headphoneStateResult) {
Log.i(TAG, "Headphone state connection state: " +
headphoneStateResult.getHeadphoneState()
.getState() == HeadphoneState.PLUGGED_IN));
}
});
Snapshot API를 사용하여 현재 위치 가져 오기
// Remember to intialize your client as described in the Remarks section
Awareness.SnapshotApi.getLocation(client)
.setResultCallback(new ResultCallback<LocationResult>() {
@Override
public void onResult(@NonNull LocationResult locationResult) {
Location location = locationResult.getLocation();
Log.i(getClass().getSimpleName(), "Coordinates: "location.getLatitude() + "," +
location.getLongitude() + ", radius : " + location.getAccuracy());
}
});
Snapshot API를 사용하여 주변 장소 가져 오기
// Remember to initialize your client as described in the Remarks section
Awareness.SnapshotApi.getPlaces(client)
.setResultCallback(new ResultCallback<PlacesResult>() {
@Override
public void onResult(@NonNull PlacesResult placesResult) {
List<PlaceLikelihood> likelihoodList = placesResult.getPlaceLikelihoods();
if (likelihoodList == null || likelihoodList.isEmpty()) {
Log.e(getClass().getSimpleName(), "No likely places");
}
}
});
해당 위치에서 데이터를 가져 오는 방법은 다음과 같습니다.
Place place = placeLikelihood.getPlace();
String likelihood = placeLikelihood.getLikelihood();
Place place = likelihood.getPlace();
String placeName = place.getName();
String placeAddress = place.getAddress();
String placeCoords = place.getLatLng();
String locale = extractFromLocale(place.getLocale()));
Snapshot API를 사용하여 현재 날씨 가져 오기
// Remember to initialize your client as described in the Remarks section
Awareness.SnapshotApi.getWeather(client)
.setResultCallback(new ResultCallback<WeatherResult>() {
@Override
public void onResult(@NonNull WeatherResult weatherResult) {
Weather weather = weatherResult.getWeather();
if (weather == null) {
Log.e(getClass().getSimpleName(), "No weather received");
} else {
Log.i(getClass().getSimpleName(), "Temperature is " +
weather.getTemperature(Weather.CELSIUS) + ", feels like " +
weather.getFeelsLikeTemperature(Weather.CELSIUS) +
", humidity is " + weather.getHumidity());
}
}
});
Fence API를 사용하여 사용자 활동 변경
사용자가 걷기, 실행 또는 DetectedActivityFence
클래스의 다른 활동과 같은 활동을 시작하거나 완료 할 때를 감지하려면 탐지하려는 활동에 대한 울타리 를 만들고 사용자가 시작 / 이 작업을 완료합니다. BroadcastReceiver
를 사용하면 활동이 포함 된 데이터로 인 Intent
를 얻을 수 있습니다.
// Your own action filter, like the ones used in the Manifest.
private static final String FENCE_RECEIVER_ACTION = BuildConfig.APPLICATION_ID +
"FENCE_RECEIVER_ACTION";
private static final String FENCE_KEY = "walkingFenceKey";
private FenceReceiver mFenceReceiver;
private PendingIntent mPendingIntent;
// Make sure to initialize your client as described in the Remarks section.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// etc.
// The 0 is a standard Activity request code that can be changed to your needs.
mPendingIntent = PendingIntent.getBroadcast(this, 0,
new Intent(FENCE_RECEIVER_ACTION), 0);
registerReceiver(mFenceReceiver, new IntentFilter(FENCE_RECEIVER_ACTION));
// Create the fence.
AwarenessFence fence = DetectedActivityFence.during(DetectedActivityFence.WALKING);
// Register the fence to receive callbacks.
Awareness.FenceApi.updateFences(client, new FenceUpdateRequest.Builder()
.addFence(FENCE_KEY, fence, mPendingIntent)
.build())
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
if (status.isSuccess()) {
Log.i(FENCE_KEY, "Successfully registered.");
} else {
Log.e(FENCE_KEY, "Could not be registered: " + status);
}
}
});
}
}
이제 사용자가 Activity를 변경할 때 콜백을 받기 위해 BroadcastReceiver
로 인 텐트를 수신 할 수 있습니다.
public class FenceReceiver extends BroadcastReceiver {
private static final String TAG = "FenceReceiver";
@Override
public void onReceive(Context context, Intent intent) {
// Get the fence state
FenceState fenceState = FenceState.extract(intent);
switch (fenceState.getCurrentState()) {
case FenceState.TRUE:
Log.i(TAG, "User is walking");
break;
case FenceState.FALSE:
Log.i(TAG, "User is not walking");
break;
case FenceState.UNKNOWN:
Log.i(TAG, "User is doing something unknown");
break;
}
}
}
Fence API를 사용하여 특정 범위 내의 위치를 변경합니다.
사용자가 특정 위치를 입력 할 때를 감지하려면 사용자가 원하는 위치로 들어가거나 이동할 때 원하는 반지름으로 특정 위치에 울타리를 만들 수 있습니다.
// Your own action filter, like the ones used in the Manifest
private static final String FENCE_RECEIVER_ACTION = BuildConfig.APPLICATION_ID +
"FENCE_RECEIVER_ACTION";
private static final String FENCE_KEY = "locationFenceKey";
private FenceReceiver mFenceReceiver;
private PendingIntent mPendingIntent;
// Make sure to initialize your client as described in the Remarks section
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// etc
// The 0 is a standard Activity request code that can be changed for your needs
mPendingIntent = PendingIntent.getBroadcast(this, 0,
new Intent(FENCE_RECEIVER_ACTION), 0);
registerReceiver(mFenceReceiver, new IntentFilter(FENCE_RECEIVER_ACTION));
// Create the fence
AwarenessFence fence = LocationFence.entering(48.136334, 11.581660, 25);
// Register the fence to receive callbacks.
Awareness.FenceApi.updateFences(client, new FenceUpdateRequest.Builder()
.addFence(FENCE_KEY, fence, mPendingIntent)
.build())
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
if (status.isSuccess()) {
Log.i(FENCE_KEY, "Successfully registered.");
} else {
Log.e(FENCE_KEY, "Could not be registered: " + status);
}
}
});
}
}
이제 BroadcastReciver를 만들어 사용자 상태의 업데이트를 받아들입니다.
public class FenceReceiver extends BroadcastReceiver {
private static final String TAG = "FenceReceiver";
@Override
public void onReceive(Context context, Intent intent) {
// Get the fence state
FenceState fenceState = FenceState.extract(intent);
switch (fenceState.getCurrentState()) {
case FenceState.TRUE:
Log.i(TAG, "User is in location");
break;
case FenceState.FALSE:
Log.i(TAG, "User is not in location");
break;
case FenceState.UNKNOWN:
Log.i(TAG, "User is doing something unknown");
break;
}
}
}
