Monitoring Location Settings in a Library

阅读更多关于 Monitoring Location Settings in a Library

问题 I'm working on a library that can be used to monitor geofences on Android devices. I've noticed that the geofences I register with Google Play Location Services GeofencingApi class are lost after I turn Location Services off and back on in the device settings. I have seen folks suggesting that I need to register for the android.location.PROVIDERS_CHANGED broadcast receiver in my AndroidManifest.xml file. I've done that -- but this broadcast receiver only gets called when I add and remove test

Are Android geofences surviving a reboot?

阅读更多关于 Are Android geofences surviving a reboot?

问题 is the system persisting them or do I have to add them again them after reboot? I have not found anything about that in the documentation at https://developer.android.com/training/location/geofencing.html 回答1: Geofences will not persist on reboot. I have tested and you can find the sample here. You have to listen for BOOT_COMPLETED action and add geofences again.

阅读更多关于 How do I use the Android Geofencing API?

问题 I have been testing the new Google Play Geofencing service API. I downloaded the sample code from the Android developers site. Next, I ran the example code on an Android device (Galaxy Note 2).

While running the sample code, one thing I have noticed is that when I am already inside the geofence range and then add the geofence to LocationClient , nothing happens. I had already read

阅读更多关于 Do Geofences remain active in android after a device reboot

问题 I'm writing an application that needs to use geofencing for when someone enters/exits multiple sites over the lifetime of the application being installed. My implementation of geofencing (very similar to the second link below) is all working fine when I first install the application, both when moving in/out of the geofences and when using mock locations to simulate it, until a device is rebooted. On reboot neither mock locations nor actually physically moving in and out of a geofence appears
