Is there any native app for Android FAX?

Question

I want to develop a FAX application.I searched on google and found some links ,applications for developing FAX apps on android.But I want to develop application using native app

Answer 1

You CAN record and play audio during a voice call on Android, I do it all the time! I record all my calls and play them back to other people whilst in a voice call, regularly. I also play people music from my phone, whilst in a call.

I don't know where you're getting your information from, maybe an old version of Android or a stock ROM from a network provider or manufacturer which have crippled the hardware in software but Android certainly DOES allow the recording and playback simultaneously during a call. Because of this I can record ANY quality I wish, from 3GP rubbish all the way up to CD quality, although there's no point on voice calls.

Because of this it is ENTIRELY possible to create a "Native FAX" application (as someone once termed it) on Android to send AND receive any FAX and keep records (files?) of such, just like any MMS, SMS, recorded phone call etc.

The only provision that would be required on top of core FAX functionality would be the ability to distinguish between voice calls and FAX data prior to picking up the call, which is currently only 100% accurate if you provide two different numbers or answer every call with software and miss voice calls (or piss people off calling your mobile who expect a human to answer).

You could get around this issue by assigning different numbers to a white-list for the FAX application to automatically answer but anyone using the same application would still have to call you first to confirm that you will let the FAX application answer the next call from them should they want to send you a fax.

It seems like a lot of messing around but I'm sure someone will implement sending and receiving any FAX from Android directly some time soon. Someone once said the "GSM modem (router)" inside mobile phones don't have the "hardware" to send and receive any FAX but we are not relying on hardware for the analogue FAX signal to be generated or decoded NOR are we using the GSM modem in DATA mode, therefore that argument is severely flawed.

We are however using the phone to transmit voice data (which happens to be carrying the analogue FAX signal generated by the software) which is in turn converted by the hardware into digital and transmitted digitally over the GSM networks. There's a huge difference in the application of technologies here, even though we are ultimately using the same "GSM modem (router) hardware" at the exit and entry point to get the job done. What happens inside the processor of the phone has absolutely nothing to do with the "GSM modem router" therefore we can essentially generate and manipulate any analogue signal sent to it before it does it's encoding.

Ok, now we have all this information out of the way, someone PLEASE develop a "Native FAX" application for Android :-)

Thanks
