I have 2 android applications 1st is running on android 4.4 and 2nd will be contemporary. I want to setup one to one communication between these two using socketIO, there will be thousands of such pairs at a time communicating with each other. How can I achieve this?
I have already tried and able to setup a communication with fixed port by following these websites https://socket.io/get-started/chat/. and https://socket.io/blog/native-socket-io-and-android/
Is it possible with or without knowing port in advance or any another method possible to achieve the need? Please elaborate the logic or any sample available to follow.
Thanks in advance.
So I am trying to create an app that can answer and reject incoming calls.
I've trying every single solution possible than I could find like using the audio manager for lower version then for higher versions use the media button and for Oreo+ use the answerRingingCall method. But none works. ITelephony is Dead and does not exist. And I can't manage to get it working even though I know it's possible since I have seen apps that can do it.
Can someone please help me find a solution?
Thanks in advance.

So, I've created an app and I want to be able to Add bluetooth devices to it (BLE or not). After I've added them, i want to display them in a different activity. I've looked for lots of tutorials(Stackoverflow and others) but couldnt find something specific.
I am a beginner and i used Kotlin to create the app.
Not exactly sure what you're looking for, but perhaps this SensorTag sample app is a simple enough example of what you're looking to accomplish?
It relies on Kotlin Coroutines to scan for nearby SensorTags, then allows you to select one, which navigates you to another Activity and connects to it, then displays sensor data.
I would like to recommend to use the rxJava for the BLE Scanning. For scanning the tags for forground and background working fine '
For view the demo on github rxAndroidBle_github_demo
on this library handled all exception.
I hope this will work for you !
I am currently working on an Android Application developed in Delphi 10.2 and have most of the functionality that I need working. However I am trying to get my head around the following SharedActivity.getContentResolver.registerContentObserver. I what to use this for detecting when an SMS has been sent via content://sms/sent URI.
I have the code that will go and get the message using sharedactivity.getcontentresolver.query but just struggling with the ContentObserver part in Delphi. Have spent 2 days searching for an example but found nothing. Maybe it is not possible!
