Is it possible to wiretap a phone conversation on Android?

It's not about the wiretapping special services any special equipment or bugs, and technically feasible means of API, and to transmit audio data to another subscriber or a server.
Mobile development itself is not engaged, so interested in you - specialists)
The first thing that came to mind, record sound from microphone to a file and then upload on a server when connected to wifi.
Are there other ways? Is there a possibility to hide the application (in addition to the substitution of icons), for example, install as a system service. Ways of identifying, eliminating, of course, disassembler))
A friend complained that he was somehow listening. Paranoia, in a word) But was curious to understand with the technical side of things)

On Android without rooting generally doesn't get such realize. That is, theoretically it can write, but the decision will be massive and not very differently would work on different devices.

Of course you can, even without root. I baby set a program for parental control, then bought. All without rooting put, though not without him recording Vkontakte, vibera and other messengers. But texting and talking is no problem.

As standard it is impossible to listen to. Only Ruth, or third-party applications. A lot of them and each something better, something worse. The above service is good - used it. Liked. Now testing Reptilicus for drying phones.
