Emulator's Location simulation not working

问题:

I would like to lower the minimum API level of my application to 4.4(KitKat) from 5.0(Lollipop)

Sadly I couldn't get any real devices so I have to work with an emulator.

My app is heavily based on user's location so the main testing must be target the location changing feature.

I try to use location simulation with the official Google Android Emulator. (x86)

I have made a 4.4 Emulator and is working fine, my app works fine but when I try to send locations via the Extended control panel nothing happens.

If I load a GPX file the locations appear on the table of the extended control panel inside the GPS data playback but the device does not get any locations.

I fill the lat and longitude click on "SEND" but nothing happens.

I have also tried to simulate location changing from the Android Device Monitor's "Emulator Control" tab

The "Send" button is not clickable at all, the long and lat fields are disabled and I cannot fill anything. The "GPX" and "KML" tabs are also disabled.

I have also tried to use the Gps Emulator plugin as the following:

The progress bar do increases, so not like the first 2 methods I have tried this is finally looks like actually doing something but the emulator still not getting the location changes. Not at all.

I have tried a fourth method via command line:

telnet localhost 5554

But I have Connection refused error message.

So I cannot try to send locations via:

geo fix <longitude value> <latitude value>

(Telnet is enabled on my Windows)

I had the same problem with the SDK Tools version 25.1.7. I've updated them to 25.2 rc1 and it now works.

Beware that you cannot install the RC version from Android Studio. You have to launch the separate Android SDK Manager to see it.

Relaunch the emulator and check that you are indeed using the latest version in the Help/About screen of the Extended Controls windows.

I had the same problem, but I managed to fix it.

Run Google Maps and accept confirmations at least once until you see the map. Do not forget to set your location setting to ON/High accuracy, as shown in the screenshot below.

Using OS X and Android Studio, had the same problem and what worked for me was: going to the actual phone (emulator) Settings, Location, and turning off the location and turning it back on. Tested again, and started working.

I think it doesn't matter that much, but the Emulator version: 26.0.3-3965150.

回答4:

In my case, the reason was location settings in phone settings set on "Battery saving". Switched it to "High accuracy" and it worked.

回答5:

I had to set the location to Device Only on the emulator for it to work. Sometimes have to switch between modes. Device only forces the use of GPS only and not WiFi, Bluetooth, etc.

回答6:

a simple emulator restart did the job for me (long click on shutdown button and select restart)

I noticed the same thing, but then I looked in the extended menu on the emulator itself. You can update the location through the emulator menu.

I also had this issue, I took over a skeleton project from someone else and could not get the emulator to pick up the GPS location.

In my case the issue was the LocationManager chosen by default in the project crested in Android Studio, which was using Network and not GPS
