How to get location from only GPS not with Network provider.
I know this can manage with the old verion of Location classes but How can i manage with updated library.
Check this out.
You can use only the GPS part but be warned that GPS consumes a lot of batery...
Use it wisely!

I am trying to build a video streaming platform and I need to implement a limited devices login feature just like netflix. I have seen some people using node device detector to get the device type from the useragent, but I don't think this is a good solution since the user agent can be faked. Please any ideas on how to effectively implement this?
Found a solution to my own answer, I can use fingerprint.js to identify devices and store in mongodb. and I found an open source version for fingerprint.js that is broprint.js
On the Instant Play Games site google recommends the following:
Integrate sign-in using Google Play Games Services and a cloud save
solution to preserve progress in the game.
However in this other document the following is stated:
If the player is using a device that runs Android 8.0 (API level 26)
or higher, and if your game specifies a targetSandboxVersion of 2,
then the player's progress is transferred automatically to the full
version of your game. Otherwise, you must transfer the data related to
player progress manually. To do so, use one of the following APIs...
So it seems that cloud saves are not needed, there exists a simple API for transferring progress to the main app. So why is cloud save recommended? Am I missing some aspect or restriction of instant apps?
I found at least one reason for this, which seems critical enough:
The instant app data does not persist over for example restarting the device. More info here.
I want to track a vehicle and send its coordinate locations to multiple mobile devices at the same time. Is there a way to do that? i also need to send the live feed of the buses' current location Can i do it with agora.io?
Agora Aignaling SDK is perfect for this
You can get started through their demos on Github for different platforms.
I am new in android and wanna get user current location using GPS_PROVIDER, but every time getting different-different location how can I use Google Play Services. and what is the best way to get accurate location in android.
Thanks you.
In general there are two different types of locations available through the Android API.
One is the GPS-Location which only works outdoors and which has an accuaracy between 5m and 50m.
The other kind of location is the so called Network-Location which is a loaction measure based on Wifi Networks in you surrounding and GSM-Base-Stations which have a accuracy between 100m and 1500m. This localization technique also works indoors, because it only requires you smartphone to have network access. The accuaracy gets better in urban areas where a lot of Wifi and GSM-Base-Stations are located. The more GSM-Base-Station / Wifi hotspos are available the better is the accurarcy of the loation measurement. It can also get down to 5m.
When requesting such an location Google does internally some magic to compute the position. This request requires a internet connection (you don't need to explicitly give the permission). Interanally Android sends a request to a Google server which contains fingerprints of the surrounding GSM-Base-Stations and afterwards computes your location (if you are curious you can find the code here).
With GPS-bases location the location accurarcy is the same all over the world without any internet connection, but works only outdoors.
With my applications I implemented a logic which detects if GPS is present or not and if not I switched to network localization, this works fine.
The Java ME Location API says it supports:
Mobile Network based positioning.
GPS
Short Range Beacons
Quite a number of phones support this API (JSR179). However, some phones don't have an inbuilt GPS module, is it still possible to use this API to obtain the phone's current location?
Mobile Network based positioning.
The security settings will control if you can access this, the service provider may also make a charge.
From my very limited experience of J2ME, you can set the phone to not allow an app access to private data (such as location) and to charged for services (such as location) - you can also set it to popup a request for the user to authorize it.
J2ME is pretty well designed to gracefully fall back to whats available and hide a lot of the details.
Yes, some GPSless S60s (e.g. N70) give location through this API when used with an external GPS device attached via Bluetooth. Others may possibly give you approximate location using CellID.
