我正在为 Android Wear 构建Android应用。为节省电池,我试图使用Geofences来跟踪您是否进入或退出某个位置。但我无法让它发挥作用。
首先,我不确定Android Wear是否支持Geofences? (独立?)我有一个华为手表2 LTE,其中包含一个GPS天线,我已经有了FusedLocationClient工作,所以我知道GPS工作。我还有我的地理围栏代码正在工作手机没问题。
当我运行代码时,我得到以下异常:
com.google.android.gms.common.api.ApiException: 1000:
我在Google API documentation上发现这意味着:GEOFENCE_NOT_AVAILABLE
这不会给我额外的信息。
这是我写的开始创建地理围栏的服务:
public class GeofencingService extends Service implements OnSuccessListener, OnFailureListener {
private static final String TAG = "GeofencingService";
private static final int NOTIFICATION_ID = 1;
private GeofencingClient mGeofencingClient;
private List<Geofence> mGeofenceList;
private NotificationManager mNotificationManager;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
mGeofencingClient = LocationServices.getGeofencingClient(this);
mGeofenceList = new ArrayList<>();
createGeofences();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
showNofification();
setupGeofence();
return super.onStartCommand(intent, flags, startId);
}
@Override
public void onDestroy() {
super.onDestroy();
mNotificationManager.cancel(NOTIFICATION_ID);
}
private PendingIntent getGeofencePendingIntent()
{
Intent intent = new Intent(this, GeofenceBroadcastReceiver.class);
return PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}
private GeofencingRequest getGeofencingRequest() {
GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
// The INITIAL_TRIGGER_ENTER flag indicates that geofencing service should trigger a
// GEOFENCE_TRANSITION_ENTER notification when the geofence is added and if the device
// is already inside that geofence.
builder.setInitialTrigger(INITIAL_TRIGGER_ENTER | INITIAL_TRIGGER_EXIT);
// Add the geofences to be monitored by geofencing service.
builder.addGeofences(mGeofenceList);
// Return a GeofencingRequest.
return builder.build();
}
private void setupGeofence()
{
try{
Log.i(TAG, "Setting up geofences...");
mGeofencingClient.addGeofences(getGeofencingRequest(), getGeofencePendingIntent()).addOnSuccessListener(this).addOnFailureListener(this);
} catch (SecurityException ex)
{
Log.d(TAG, "Exception: " + ex.getMessage());
}
}
private void createGeofences()
{
Log.i(TAG, "Creating geofence...");
mGeofenceList.add(new Geofence.Builder()
// Set the request ID of the geofence. This is a string to identify this
// geofence.
.setRequestId("Test1")
// Set the circular region of this geofence.
.setCircularRegion(
50.03535,
4.33139,
100
)
.setExpirationDuration(NEVER_EXPIRE)
// Set the transition types of interest. Alerts are only generated for these
// transition. We track entry and exit transitions in this sample.
.setTransitionTypes(GEOFENCE_TRANSITION_ENTER | GEOFENCE_TRANSITION_EXIT)
// Create the geofence.
.build());
}
private void showNofification()
{
Intent appIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, appIntent, 0);
Notification notification = new NotificationCompat.Builder(this, NotificationCompat.CATEGORY_SERVICE)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(getText(R.string.location_service_title))
.setContentText(getText(R.string.location_service_text))
.setLocalOnly(true)
.setOngoing(true)
.setContentIntent(contentIntent)
.build();
mNotificationManager.notify(NOTIFICATION_ID, notification);
}
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG, "Exception: " + e.getMessage());
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
setupGeofence();
}
}, 2000);
}
@Override
public void onSuccess(Object o) {
Log.d(TAG, "Success!");
}
}
Here is also a github link to the example I wrote.
希望有人可以帮我解决这个问题,因为我已经尝试了所有我知道的事情:)

在您阅读文档时,看到错误代码与GEOFENCE_NOT_AVAILABLE
相对应,另外根据@ Mr.Rebot评论:
“并非所有磨损设备都有硬件支持这个[...]”
您可能认为您的Huawei watch 2设备 GEOFENCE不可用。
您也可以直接要求to Huawei support进行确认。

未打开位置信息时也会出现此错误。您需要启用位置才能启用地理围栏。
