How does Android Auto Wifi Connect algorithm work? - android

How does the auto wifi connect algorithm work on the Android phone? For ex: when I go home, it auto-connects to my home network. When I step into Starbucks, it automatically connects to the Starbucks network. I assume there is a "background service" running on the phone at all times. Is this true?
If so, does this service constantly check the GPS location and then try to simply connect to the local network that was last inside that GPS coordinate?
Or, does the service automatically try to find any local network and simply connect to the first one that it is able to connect to?
Or, does it automatically connect to the most frequently connected network? Does auto wifi take into account the # of times it has connected to each network?
Thank you.

Detect phone connection type from watch

I have an Android watch that can be in one of the following:
1a. standalone - connected to a WiFi network directly;
1b. standalone - connected via a cellular link (if SIM present, unlocked, etc.);
2. bluetooth connected to a phone and using the phone's connection (WiFi/cellular);
It can also be that both the watch and the phone have a SIM (though this is less important).
On the watch I run a standalone app (no counterpart app/service on the phone) and I need to find the 'end' connection type I have when tethering. Namely, using the watch only, I need to know if I am tethering via a WiFi or via a cellular connection.
Or, in other words, when tethering, I need to know if the phone (to which the watch is connected via bluetooth) sends my data further using WiFi or a cellular connection.
I did look around for a solution but what I found only allows identifying the type of connection the watch has, e.g. WiFi, cellular or bluetooth.
Is this even possible? Thanks in advance for your help!

Multipath TCP on Android / IPhone

I have a device that creates a WiFi network that is not connected to the internet. This device hosts a website using IIS. To operate the device, a smartphone connects to the WiFi and browses the site. The smartphone needs to get data from an api (internet) and pass it to the website on the device.
I have tried to remove the default gateway setting from the DHCP server on the local WiFi, but this is not permitted on the device.
I have not been able to find an app that will allow both WiFi and Cellular data to be used simultaneously.
If I were to allow the device to connect to a hot spot that the smartphone creates, the smart phone cannot access the device's WAP.
The next option I'm considering is to toggle the WiFi Off and On during the process.
I'm wondering if anyone has another solution to this issue?

How to connect to a saved wifi in android?

I know there are methods to add and connect to a wifi network
How do I connect to a specific Wi-Fi network in Android programmatically?
But what I need is to connect to a network that is already been saved by the user in the device,
Basically I want to connect to the best available network (which user has been connected to earlier) around. I can manage to find the nearby wifi signals and get their strength then I want to connect to the best one.
Also there are couple of inactive threads in SO asking the same question, unfortunately none of them has any answers:

GPS and WiFi hotspot clash on Android

I can't get GPS location when creating portable WiFi hotspot through my device. Its running on Android 2.3.7. Basically my app fetches the GPS location of the device and sends it to a server(in LAN). To simulate this condition, I created a LAN with my mobile and Laptop(acts as server). Hotspot is created through the mobile. It used to work if LAN is created by some other means, connectifiy or Router connection. Except a hotspot. I want to know if hotspot clashes with the GPS receiver. I seriously doubt it though.
If you are using LocationClient then in that case location is fetched using GPS,Wifi or Cell ID..Now if you make your device as a Wifi Hotspot then it might happen that your device will look to fetch location using GPS. And if you happen to be indoors then there is a remote possibility of getting location.Hope this answers your question

how to detect that app connected to local wifi

I have two buttons in my app one will be on for local wifi(specially for "ati"), other will be on for if connection is specific server is available like www.google.com
Please help that how can detect the app is connected to local wifi and also how can detect that connection is available to specific server , same behavior as of Reachability in IOS programming
You can use the WifiManager class to get the state of Wi-Fi. I think only way to check whether connection to specific server is available to actually connect.
