First,thank you for your attention to my question
I'm planning to design an Android GPS locating application
here are my difficulties and situations
(1)my computer hardware has been out of date for a long time and running an android emulator for debugging is really time-costing,thus i bought a real device(android cellphone) one week ago,in the aim of replacing emulator during debugging
(2)i know how to send location datas to an emulator via "DDMS/Emulator Control/Location Controls",but it is disabled for a real device
(3)i am programming indoor,thus using physical gps locating function is not acceptable(even if i turn on "a-gps")
(4)i have found another topic here: Android mock location on device?
however,i can't open the detail links,like "Andrews link"," http://dehuysser.appspot.com/blog/android-developer-shell-released"
I guess these web sites are forbidden by my country......
Here are my questions:
(A)i have found some codes of making mock loation datas ,but these codes can not activate "onLocationChanged" function
However, i wonder if there is a way to send locating datas from PC to real device via USB port(i'm in USB debugging mode), just like sending locations from DDMS to emulator?
(B)i've got the information that, it is possible to send "geo fix" command to emulator as well as to a real device, by "telnet localhost ", but how to check out the port number occupied by my real device?
i know that 5554 port is used for a emulator,but what about the real device?
i've tried to command "netstat" in terminal, but it's a shame to say that i don't know which port is for my android phone......
(C)If my (A)(B) question is not practical，then what's "settings/applications/development/allow mock location" used for?
Please help me, and thank you for your answer!
I have wrote an app exactly for this (this functionality is not available on phones by default) - it's open source and provides exactly the same interface as the emulator (telnet to :5554 and run "geo fix ..." or "geo nmea"): in app store MockGeoFix
The easiest way of using mock data is using the mock test location provider API. It's at the bottom of the documentation page. I've tried it out and location is received in the onLocationChanged callback. Here is some code that you can try out.
The port used by adb is usually 5037.

How can I get GPS coordinates from an Android device via a terminal?
I've searched everywhere and all I've found is Java code for apps, but not a decent method by just using a plain shell. I'm not interested in passive geo-location that uses nearby cell towers and wifi endpoints, but a method that uses the built-in GPS on a device. Is this even possible? Oh and side question:
Is it possible to toggle GPS via a terminal when rooted without any user confirmation?
Edit:
I found a way to execute what I want properly. Using /system/bin/settings, I can toggle GPS itself without user confirmation. After that, I can run a binary I made with Android NDK, and using JNI I can request the users current location.
You can get latest GPS location using this adb command
adb shell dumpsys location
I try to change the network type from android emulator. From the official android documentation (https://developer.android.com/studio/run/emulator-commandline.html), i want to use network to change LTE/UMTS/GPRS network type. I create a new emulator from the last Android Studio 2.2 and connect with telnet. I run the help command (after authentication) and I get :
Android console command help:
help|h|? print a list of commands
crash crash the emulator instance
kill kill the emulator instance
quit|exit quit control session
redir manage port redirections
power power related commands
event simulate hardware events
avd control virtual device execution
finger manage emulator fingerprint
geo Geo-location commands
sms SMS related commands
cdma CDMA related commands
gsm GSM related commands
rotate rotate the screen by 90 degrees
I don't see network as explain in the documentation and when I try to run a network command, I get an error... Anybody have already met this issue ? Any idea how to solve it ?
Ok, seems to be delete in last versions of the emulator. I hope the android team will implement this feature soon.

I have installed the Android TV SDK Developer preview for Windows. I am in a corporate intranet environment. I can start the Emulator, but the main screen endlessly loops with the "Preparing Recommendations" animation. I can navigate to the Settings and see that there is no network (no wired and no ethernet).
I suspect this might be a proxy issue. I have tried launching the Emulator with the following command:
C:\Eclipse_w_Android\adt-bundle-windows-x86-20140624\sdk\tools>emulator -avd AVD_for_Android_TV_1080p_by_Google_X86 -http-proxy http://MY_PROXY_IP:8080
(MY_PROXY_IP is replaced with my company's IP address)
It launches the Emulator but doesn't seem to have any effect on the network.
Has anyone else been able to get the Android TV Emulator to fully load in a heavily firewalled / proxied environment?
I thought I was experiencing this issue as well (and had originally commented as such), but I later realized that there was no actually connectivity problem. Two things to note:
"Preparing Recommendations" will appear indefinitely, and I presume this is simply because there are no apps by default feeding recommendations to populate this screen.
Both the Ethernet and Wireless items will show that they are not connected. However, if you run an app that uses the network (a simple WebView is sufficient as long as the app has INTERNET permissions), you'll see that it connects just fine.
I would suggest trying a test app to check connectivity, as there is no other indicator I can find suggesting that it is working properly. I suspect you'll find that all is well.
you probably forgot the first part username password # server port
your company probably has the ip setup with username password
I was having issues with the DDMS's ability to send GPS data to my emulator (i needed speed, accuracy, heading, etc all to change but couldn't get that to work with DDMS). Anyhow, I wrote a quick script to connect to the debug port and send nmea sentences following a track from a gpx file (nmea sentences modelled off an nexus s) but added the extra data i needed. I know there are other gps emulators out there, but for various reasons I ended up writing my own.
The question I have is, is there a way to do this to a real phone? I've trawled through the ddms info i can find and cant find much of use?
I've seen one emulator that can do this via bluetooth, but had trouble with it.
The same way you can send GPS data to a phone, which must have USB debugging and Mock locations allowed in settings.
I am developing a GPS enabled application on Android. There is no problem with the map display, but I want to test how my code would react to the situation in which the user enters a room, basement or a cave, so that the device would stop receiving any signal. My question is whether I can simulate this programatically or by using the DDMS, and if so, then how?
P.S. The point is to test it all on the emulator, not a real device.
Thank you.
Fixes only come into the emulator when you push them over (e.g., via the Emulator Control tab). If you don't want the emulator to receive fixes, don't send them.
