当我尝试在三星设备中跟踪开始行走或停止行走时，Awareness 无法识别并且不会更新当前状态。

活动：

公共类 MainActivity 扩展 AppCompatActivity 实现 GoogleApiClient.ConnectionCallbacks，GoogleApiClient.OnConnectionFailedListener {

private static final String TAG = "awareness_poc";

private GoogleApiClient googleApiClient;
private PendingIntent requestPendingIntent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Intent intent = new Intent(FenceReceiver.FENCE_RECEIVER_ACTION);
    requestPendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, intent, 0);
}

@Override
protected void onStart() {
    super.onStart();
    googleApiClient = new GoogleApiClient.Builder(this, this, this)
            .addApi(Awareness.API)
            .build();
    googleApiClient.connect();
}

public void removeFences(View view) {
    FenceUpdateRequest request = new FenceUpdateRequest.Builder()
            .removeFence(WALKING_START_KEY)
            .removeFence(WALKING_STOP_KEY)
            .build();

    Awareness.FenceApi.updateFences(googleApiClient, request)
            .setResultCallback(new ResultCallbacks<Status>() {
                @Override
                public void onSuccess(@NonNull Status status) {
                    Log.i(TAG, "Fences successfully removed.");
                }

                @Override
                public void onFailure(@NonNull Status status) {
                    Log.i(TAG, "Fences could NOT be removed.");
                }
            });
}

@Override
public void onConnected(@Nullable Bundle bundle) {
    AwarenessFence walkingStartFence = DetectedActivityFence.starting(DetectedActivityFence.WALKING);
    AwarenessFence walkingStopFence = DetectedActivityFence.stopping(DetectedActivityFence.WALKING);

    FenceUpdateRequest request = new FenceUpdateRequest.Builder()
            .addFence(WALKING_START_KEY, walkingStartFence, requestPendingIntent)
            .addFence(WALKING_STOP_KEY, walkingStopFence, requestPendingIntent)
            .build();

    Awareness.FenceApi.updateFences(googleApiClient, request)
            .setResultCallback(new ResultCallback<Status>() {
                @Override
                public void onResult(@NonNull Status status) {
                    if (status.isSuccess()) {
                        Log.i(TAG, "Fence was successfully registered.");
                    } else {
                        Log.e(TAG, "Fence could not be registered: " + status);
                    }
                }
            });
}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}

}

广播接收器

ublic class FenceReceiver extends BroadcastReceiver {

public static final String FENCE_RECEIVER_ACTION =
        "com.iwsbrazil.lab.awarenesspoc.FENCE_RECEIVER_ACTION";
public static final String WALKING_START_KEY = "walking_start";
public static final String WALKING_STOP_KEY = "walking_stop";

@Override
public void onReceive(Context context, Intent intent) {
    FenceState fenceState = FenceState.extract(intent);

    if (fenceState.getCurrentState() == FenceState.TRUE) {
        if (TextUtils.equals(fenceState.getFenceKey(), WALKING_START_KEY)) {
            sendNotification(context, "You Started Walking", 1);
        } else if (TextUtils.equals(fenceState.getFenceKey(), WALKING_STOP_KEY)) {
            sendNotification(context, "You Stopped Walking", 2);
        }
    }
}

private void sendNotification(Context context, String text, int id) {

    NotificationCompat.Builder builder =
            new NotificationCompat.Builder(context)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("Awareness")
                    .setContentText(text)
                    .setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE | Notification.DEFAULT_LIGHTS);

    NotificationManager manager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(id, builder.build());

}

}
