I have two android devices, and I want to connect them using bluetooth programming, sorry for say but I don't want to see the links on Android Developer Documentations.
I want to connect them without any permission like password or anything else, so just simply connect two devices and start sending files and receive files without any permission,
how can I implement such concept?
Help me please, I am stuck on this.
Short, you can't. You'll need at least the Bluetooth permissions as illustrated in the tutorial on the Android Docs-Page.
You have everything here :

Get the code, run it and see how it works.

I have this Samsung-watch
I implemented a mobile application for my graduation project, it is a triaging system that will serve the people who has an injury or illness,
In some cases we need to ask the patient about his heart rate, we want to take this data from the watch instead of asking him about it.
I searched for this and founded that I need to install Tizen extension to the visual studio, I want to write a code that take heart rate, then connect this code to my android application,
Does anyone know or can help me to do this?
Does anyone know the steps that i would follow to complete this process ?
You will find a lot of help from Samsung Developer Site.

I would like to know if there is any way to make a GPRS / GSM module (SIM800L) as a "default" connection in android things that allows browsing the internet and making requests using the Android libraries.
Seems no, because as in this answer of Blundell described: the source code is not available for Developer Preview. But You can use UART and AT commands.
This is possible. I have been able to integrate SIM800L TO RPI3 running Android Things via UART and AT commands. I am however using it for sending SMS and not for Internet connectivity. I do not see an issue in achieving that as well.
Hope this answers your question.
I am looking for a way to see what API(s) is an android app using (with request headers). I think there is some way to connect it with hotspot of our computer system but i probably forgot the whole procedure. Any help would appreciated. Thank you.
You can use wireshark for that. Here is old question and answer about that. Sniffing an Android app to find API URL
I have been searching on the internet, but I didn't find what I want, so I'd like do know if you guys know how to do this.
There's an app named AirDroid, and I think you know it, but for those who don't, it enables a communication between your device and a browser. So you can control your smartphone through the internet, if both are connected at the same Wi-fi.
Do you guys know what I have to study to do it? Android SDK has some class that enables it?
Android SDK has some class that enables it?
Not specifically.
Do you guys know what I have to study to do it?
I am going to assume that "do it" means "write my own implementation of the same thing".
Since it is a Web app, you will need to learn how to write Web apps, using some lightweight framework that is suitable for running on an embedded device.
I am trying to get a clear idea about Proximity mention in AllJoyn app and there are several explination (theories) that i find intresting but , I still want to know can Alljoyn support proximity? If yes then how do I go about it? Can I see an example using proximity or reference a sample App as im not able to find proper references to the same. The Chat app I've seen works perfectly using WiFi but how can i accomplish the same using a bluetooth? Kindly help me..Thank You in advance..
Bluetooth support is only available in the android sdk. In order use bluetooth, you either have to wait until AllJoyn is adopted by OEMs, or rooting your phone and doing some fiddling. More info can be found https://www.alljoyn.org/docs-and-downloads/documentation/alljoyn-android-environment-setup-guide#unique_21
If/when bluetooth is integrated/supported, your use of AllJoyn should be the same, as AllJoyn works to hide the communication details from you.
