Why is Network access in my geofence broadcast receiver unreliable?

由 不羁岁月 提交于 2019-12-11 13:44:37
问题 Use case: When geofence triggers we need to contact server ASAP. We have solved this with an implicit BroadcastReceiver calling a Service for several years, but problematic in new versions due to Doze and Oreo background restrictions. Attempted fixes: We moved geofence registering from implicit -> explicit broadcast receiver to get around the "background mode" restriction. We tried to do it as in Googles examples, i.e. the broadcast receiver calling enqueueWork() on a JobIntentService . The

问题 I develop an application that uses the Android Geofence API. Now I have the problem that, when the radius of the geofence is as large as 10 kilometers, it does not work, but when it is as small as 10 meters, then it works. In the documentation, Google does not say much about the radius: Android Sample Geofence API Geofence Builder API Thank you very much! 回答1: The radius determines how large or small the circle is that is drawn around the geopoint. There is not a maximum limit for the size of

Android: What is the minimum and maximum radius for geofence

问题 I am working on an Android app which makes use of geofence. I want user to decide the radius of geofence. But I want to know what is the minimum and maximum radius for the geofence so that app will work fine. 回答1: Maximum- the radius of the earth. GPS is confirmed not to work on the moon. Minimum- depends on the accuracy of your gps hardware, atmospheric conditions, etc. If everything is great, probably 10 meters reliably. If you fall back to network location, probably about 500 meters. 回答2:

问题 I'm about to implement a feature with geofences and before I get any serious work done, I need to know whether geofences remain active after the first transition. The core of the feature is: every time I'm within x meters of point P (call this Area A ), I want Action B to occur. What I need to know is Do I just have to add a geofence with Geofence.NEVER_EXPIRE and rest assured that I will get a PendingIntent every time I enter the specified area regardless of elapsed time, reboots, etc OR Do

Geofence - problem in triggering 'GEOFENCE_NOT_AVAILABLE'

问题 I do app with geofencing use and since I started to work with it I get to broadcastReceiver the transitions and when I turned off the GPS location I got an alert with code GEOFENCE_NOT_AVAILABLE and I started a service to reregister the geofences when I will turn on the GPS. Now I took a few days break and suddenly my broadcastReceiver doesn't get alerts when I turn off the GPS. I don't understand why? *when I enter/exit from location (like I defined in the geofences init) I trigger the
