i am planning to build a voice authentication system for android devices. Simply meaning instead of the login screen where you have to type your password or draw the pattern, you only only need to say one word such as "Login" and the phone authenticates you and automatically unlocks the phone.
I was initially planning to implement it on windows but i am afraid that windows might not support voice bio metrics.
So my question is will android support voice bio metrics for unlocking a phone?
Are there any voice bio metrics libraries for android ?
I did a google search but couldn't really find what i wanted. I have also found out some voice biometrics apps such as nuance but their authentication is implemented for a different purpose.
Thanks.
Android does support voice authentication by its own. You can have this feature by using an external library. Several companies offer online voice biometrics, but only a few offers offline.
If you are looking for offline voice authentication I would suggest the following companies:
Neurotechnology
Agnitio
They both support multiple platforms.

am working on an e-commerce app, where buyers and sellers should be able to initiate conversation via an in-app chat interface and negotiate prices and setup meeting points for exchange .
Is there a Chat SDK that can make this easy for me or do i have to build a chat interface for my app from scratch and if so, what's the logic to be used.
A good example is a cryptocurrency platform like paxful.com where sellers and buyers Chat on the platform and carry out transactions or Upwork where freelancer and employer initiate chat on the platform about how the project should be carried out.
Firebase-Chat-Sdk will be helpful for you. You can see this Demo application using Firebase chat.
Other than this if you want to make a chat interface along with your own back end server then you need to create back end API and front end interface from your own.

Since various OCR Api's like Tesseract ,Blink ocr and abby fine reader dont do much with scribed text reading.If there is any good opensource OCR API or SDK (like a jar ) which can be used to read scribed card text in android or java and also I found card.io SDK for android.Is it good enough though.
Please explain with code examples.
I think I found a perfect match,an SDK called card.io and it comes for both android and ios versions and it's free I guess.So I am going to try it.
Mainly I want to make it read the scribed text on cards.
The demo published on their site card.io seems to be promising.Though the sdk just scans the info and you have to process it to a gateway.

Lets say we are building a online shopping app like amazon,flip-kart,etc .In this case implementing a framework while building app would be very good practice. I want to know famous frameworks developers uses nowadays to build such kind app. Lets assume back-end engine is developed by restful service.
Please share your thoughts about the Spring Android framework.
There are some Android ready frameworks available.
According to the Eclipse Open Source Developer Report 2012, 60 percent of open source developers writing Android or iOS apps use only the official SDK. Among those who use cross-platform frameworks, the choices, ranked from first to last were:
jQuery Mobile (28.6 percent)
PhoneGap (17.9)
Sencha Touch (7.9)
Dojo Mobile (4.9)
Titanium (2.8).
You can have a look at
SproutCore: This HTML5-driven framework offers a "clean" MVC architecture, and emphasizes performance optimization and scalability.

we are developing an simulator application where user can create simulation and run the logic. now in second phase of our project we required hardware triggering using web based application . i required some information on how i am going to interact with PLC machine using my java code we are using modbus serial communication but can be changed if you have some other better solution. as par my research we have seen OPC server but i didn't get anything from that. i want some one can help me to understand what will be flow. how to proceed with this. do i have to write driver for communicating with my application and PLC.
What need to be done complete approach this task. if you have any link please share
thank you
I don't know if this is helpful for you, but we have a java library (LGPL 3.0) which talks natively via TCP/IP with S7 devices.
have a look at http://openscada.org
we also have a OPC interface which is written in plain JAVA, no Windows required.
I use this.

It is cheap, and the examples and support are good. Their support is out of Australia, though, so you will either be answered at 6:00 at night or while you're asleep.

Is there any Java API to make a phone call to a mobile(provided that service provider support will be arranged to make that call)?
myProgram(A) --> Java API to make a call like Skype(B) --> PSTN/Mobile network support(c)
Module A will be my Java code and it'll call the B's API which will in turn transfer the call to my service provider.
I'm looking for an API at level B. Also, I'm not using Android. I want to run this code on my server.
I tried and landed upto skype.
For using Skype, Skype should be installed on the machine(which I don't want).
Is there any other solution to do this?
Did you already take a look on Asterisk? There is a Java API.
There is Java Telephone API (JTAPI). You can take a look at that. It have different implementations, like xtapi, gjtapi. I have worked with xtapi.
It allows you to make/receive a call.
