Viwr aims at bridging the gaps in the current android app development ecosystem.

Gaps in the current Ecosystem
1. Emulator sucks. Even if they are x86 emulators, they can't emulate the actual device experience. And using the device as a dev tool becomes difficult at times. Viwr helps Android developers to use their device as an emulator.
2. Using different Android SDK tools is super complicated. For example, fetching battery report requires a docker installation, a couple of command-line executions, dumping the report, then importing it into the docker installation (Refer: https://developer.android.com/st...).
3. Developers have to go through a lot of complicated configurations for simulating external factors like location, battery, network, etc.
4. There is no one single report that we can look at to measure the performance of an Android app.

The core mission of Viwr is
1. Help developers to use their Android devices as a complete App Development tool.
2. Give an all in one solution to quantify the performance of their Android app.
3. One-click mocking of Location, Battery, Network conditions for the Android device.

Upcoming features
1. Automated security checks for APK.
1. All in one network inspector. No more complicated setup (Charles proxy, Wireshark)

Some sample reports:
1. Facebook: https://reports.viwr.app/?id=0fb...
2. Instagram: https://reports.viwr.app/?id=c1d...
3. Airbnb: https://reports.viwr.app/?id=483...

Currently, Viwr is available for Mac. Register on https://viwr.app for getting updates.

Tech stack:
NodeJS : Singling server and session maintenance app
ReactJS: Web site and Web screen sharing widget
Java/Android: App

Technical Description:
- Android app captures screen using Projection API. That capture is streamed over an WebRTC media session
- Being a free to use service, Droidcast is only supported by STUN servers (provided by google). This app ships with some open TURN servers, but this may or may not work. (The reason for low ratings on play store)
- Session handling server is written in NodeJS. Its modified version of PeerJS.


App Description:
Droidcast is aimed at removing all the hassle Android users face while sharing their screen live on the internet. One click and you are ready to share your Android screencast with anyone in this world.

SDK:
- Droidcast SDK (not yet released) is a way to remotely debug any Android app remotely.
- Almost a single line of code, triggers logcat streaming over the internet, which can help developers to figure out bugs easily during alpha and beta testing in controlled environment.

Current solutions:
Step 1. Install and configure Android development tools (like ADB) on your computer.
Step 2. Use USB cables to connect the phone with your computer
Step 3. Use screen mirroring software like scrcpy. 
Step 4: Use screen share on the computer :-)

Droidcast:
Step 1: Click on the "Start Screen Sharing"

Adaptiv Risk Cube
A new product was introduced in 2008 that offered Business Intelligence for market risk products like Adaptiv 360 and Adaptiv Analytics. A small development team based in Cambridge and London had started initial work on it and I joined that team in Dec 2010. I have – since then – worked on number of showstopper issues , programming, testing, documentation, staging database design and multidimensional database design.

C,C++,ADBMS,Java, Advanced Java, Struts, .Net framework, C#, T-SQL, Microsft BIDS developement, Object Oriented Analysis and Development.

I was one of the 20 people who got selected for Thoughtworks OOP bootcamp where we were introduced to various OOP concepts with real life examples. The programming language was JAVA and development strategy was Test Driven Development.

Viwr : Make your Android device a powerful development tool

During the Android app development, I personally faced a lot of problems debugging issues on the remote end. Asking Logcats, and screenshots to a non-developer become a cumbersome task. Current screen sharing solutions for Android rely on ADB. 

Droidcast does not require anything. One click and your Phone Screen is sharable on a web link, which can be viewed by anyone in the world. No plugin installation, no development tool installation.
