I want to develop an Android app. It's my first one and it has to be a secure VoIP app. I was told to use webRTC and after a lot of research I'm stuck. I don't get how webRTC works. Can you help me with some steps in developing this kind of apps?
Having worked in the past with WebRTC, I just want to share this information here so that it may help people's who just want to start learning from scratch:
--> The very first thing to refer is a straight forward example by Pierre Chabardes on the GitHub. Here is the link : AndroidRTC
--> You can find here a very straight forward build scripts by Pristineio for Android & iOS to build latest version of the required WebRTC library. This requires linux machine. WebRTC Build Scripts
--> And a very good tutorial here : Introduction to WebRTC
This 3 links will get you started and you can start learning from here then.
Hope this helps you and everyone out here.

How to create an application which can be run on iOS, android, also in form of software in macOS, windows, Linux, etc.
I want to know on which platform I should create for building such application.
provided that I am a college student in 3rd year B. Tech Computer Science and want to develop this as my project in final year.
Any help will be appreciated. Thank You
Please take a look at the link I have provided. What you're looking for is called Cross-Platform App Development (if I am not mistaken). You can use a programming Language like JavaScript/TypeScript with its corresponding compatible Framework like React Native with Cordova (for plug-ins for example) to develop apps which can be used by the platforms. If you look into that, youll find information about how it can be used as a Web App (so also on Windows for example).

I am new to programming and have been learning for the past month. I am trying to build an app that can record and upload short videos like Snaps to a database. Then the app can access these videos from the database. I am learning Java and Android Studio currently to make the Android version of the app, but later I want to learn the iOS side to make the iOS version of this app.
I would deeply appreciate some guidance on what exactly I need to learn to be able to make this app myself.
Well you can get started with the Camera API(updated to Camera2 API) and the CameraX API which will help you with photography on Android devices.
Camera2API described here
CameraAPI Documentation
Video Recording Documentation
CameraX Documentation
Regarding storage, I suggest that you start with what is provided in the Google Documentation and work your way up from there.
Storing files on android
The best way to learn is by using the Android Developer Guides as a base and StackOverflow posts to clarify implementation problems and troubleshooting.
Cheers!

i'm starting at this world of app development and after some researches i still don't know which one to use.
For having a little knowledge in AngularJs,some recommended Ionic but, is the performance affected ?
Should i begin with Ionic Framework or Android native ?
Wether to go native or not is great battle among most app developers.
I would always opt for native, because it has every utility for the platform and supports the developer in every possible way. Hybrid aproaches are lacking nearly all of this, but are written in a cross platform language quite a lot developers are familiar with.
So on the bottom line it greatly depends on the needs of your project. But to get started, may try a little "hello world" with the android SDK and java. You will very quickly get to know a lot of the characteristics on android you will need to know even if you opt for hybrid. This knowledge will be essential, especially if you want to publish your app on Google Play or Amazon App Store.

Lately , I have been given the role of the team leader in the mobile unit in my company. We are developing for iOS and Android, and we can expand it further more to Windows phone and Blackberry. The idea is to build native apps for different platforms. So the basic task is to choose in what platform we are going to develop. Of course we can have different programmers for different platforms but we don't want to go that way. So we are trying to choose a single cross compile platform for developing apps in multiple platforms.
One of the suggestion was using Xamarin (https://xamarin.com).
Can you please tell me what are your pros and cons about this solution or any other suggestion that you find useful. We do not want to use HTML5 or any JavaScript approach.
Just a quick : "Xamarin Pros and Cons" on Google leaded me to many results. At the end your team will have to make the decision.

You should try it next time. I also suggest you to try their framework with the free version, see how it suits your team.

I've just recently(today...) found out about phonegap.
I went through all the FAQ's and I think it's a great solution for those who wish to build an app using things they already know like HTML and CSS instead of learning a new API
but...
if I'm trying to build something that requires more efficient work and stablity, I think i'm better off developing with eclipse and using the standard ADT and not the framework phonegap are offering.
Am I right or maybe just a bit prejudice?
I wanna be sure before I start
First of all, it depends of what you want to develop. Developing with phonegap can be faster and you don't have to learn java for the development, but you have to consider that mobile JavaScript capabilities are bad and the app won't work smooth(espessialy the transitions and animations). If you go Native, you will spend more time learning, but at the end you will get an app that will run faster, smoother and with best performance. In you case i would definitely go Native.
