I work on an indoor tracking project using android.I used Gps to detect location but it does not work correctly at indoor tracking
How can I solve this problem?
If you GPS signal is bad there are 2 things you can do.
One is: improve you reception (e.g. remove the roof, good outside, replace roof with glass). Now this might be a little ... tricky
The other one is: use a different technique. Bluetooth tracking (BLE beacon) for instance.
You cannot 'amplify' GPS signal. The system works by finding out how long it takes a singal to go from several satallites to your phone. If you 'repeat' or amplify the system it is going to give false results. So you can not do stuff like "put an antenna on the roof", as all your locations would return the location of the antenna.

I'm currently working on a flutter mobile application to automate traveling log for vehicle. I need to automatically log all the trips of user which are traveled using a vehicle. Is there a way to know exactly traveling mode of the user?
Also I need to start log if user starts a trip by vehicle and stop the log when user stops the trip. This should avoid the traffic jams also.
I tried to use accelerometer readings and gps location readings to determine the traveling mode. But it was not success.

I'm trying to write and app to control 3 motors using my phone wirelessly and I'm not entirely sure what a simple way might be.
I was thinking to just send an RF signal, but the internet seems to agree that that is not feasible to do so. I was thinking of Bluetooth/wifi as well, but I would like to see if there are any other options to transmit signals from my phone.
I don't want to deal with establishing a bluetooth connection every time I want to use the motors, as for wifi I would prefer something that doesn't use the internet. Am I out of luck?
Also, I'm just getting into this type of stuff, so I apologize if this question is too obvious for some people, but I couldn't find an answer to it anywhere I looked, which is why I'm here.
All help is appreciated!

Am new to android ,i want to create an android app to track indoor position using ips(wifi signals)
I need to know what are Prerequisites required for and the basic idea to develop it
You must have:
1) some wiFi antennas working around (minimum three to have the precise position in the room);
2) you must use your Wifi and check the power of each antenna.
Depending on the variations of these three levels of power, you can understand where you are. This is called triangulation.

I am trying to get signal strength readings from existing access points within a given room without having to connect to them. I am very new to android development and eclipse so I would really appreciate it if someone could give me some direction in this matter.
}
Register a BroadcastReceiver for SCAN_RESULTS_AVAILABLE_ACTION
Start scanning using wifiManager.startScan()
In the receiver's onReceive(), get the results using wifiManager.getScanResults()
Loop the result, and get scanInfo.level
A similar example can be found here. I won't implement that into your class, because you should learn something. If you don't manage to implement your class, you should get yourself more knowledge on Android programming before starting such a project.

I am pretty new to Augmented Reality so I don't understand something. i.e. I want to create an app that I will give to users at my store [hypothetical]. Whenever they are in my store the app should show info for different sections of the store [i.e. 'this is the tools section' or 'this is the gardening section'].
What is necessary to recognize indoor locations on Android and is in this case an Augmented Reality implementation the only possible solution ? Not sure if GPS coordinates are registered indoor precisely nor whether they'll be registered on that small 'distance' at all..
Have you heard of LLA markers? (Latitude,Longitude, Altitude Markers). They're more accurate than GPS for indoor tracking, but there are limitations (i.e show locations statically... it won't tell you you're 36 , 35 ,34 meters away as you walk towards something).
I would say that Bluetooth beacons is the best way to go. You can also use the strength of WiFi signals but that is vary coarse.
