问题 Before I go into location based mode I check for existence of any location providers by calling List<String> android.location.LocationManager.getProviders(boolean enabledOnly) //enabledOnly = true and checking the size of the resulting list.

问题 Sorry for my english. I'm trying to get a single location from GPS to put on global variables latitude, longitude. GPS turns on, but the activity goes on before data is retrieved from GPS. My needs in other words... method getCurrentLocation() must finish only if a location has been found and the longitude and latitude variables are filled, so I could use them in other method. I know... user has to wait... I will solve this forward showing something on screen. What should I do? Thank you I

问题 I'm using Fused Location API in my app ( getLatitude() , getLongitude() , getSpeed() , getElevation() , and distanceTo() ). It was working fine until I updated my phone (Moto X2 2014) to Marshmallow. Now I don't receive speed in the location object in my app, rest methods are responding normally. However, if I run navigation on google maps in the background, I seem to receive speed inside my app as well. Also, my app seems to work without any issues on Nexus 5X (Marshmallow) and other below

问题 I wish to receive a notification when the user enables or disables either Network or GPS locations, and importantly I wish to know which one they have changed and how.

问题 For some reason the implementation of getMaxAddressLineIndex has recently changed. Now this method returns 0 for line 1. I have an existing code, which used to work: i<address.getMaxAddressLineIndex( ). However, it is broken somehow. I don't know if it is due to the new Google Api or something else. Can someone please confirm me here what is going on? 回答1: I had the same issue and this just a workaround. if (address.getMaxAddressLineIndex() > 0) { for (int i = 0; i < address

问题 I am building an app that requires user location. I am following the Android training documentation from here which says: shouldShowRequestPermissionRationale return the boolean indicating whether or not we should show UI with rationale for requesting a permission (dangerous permission, ACCESS_FINE_LOCATION) Now in this code (taken from the documentation itself) : if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) { //
