Auto-reply on Android 8?

Question

Android

Good,
is it possible to make an autoresponder on Android 8+?
For example, if a person does not answer the call - "the phone goes up" and my message is played and the conversation is recorded - a classic answering machine but through Androyd.
Or does the OS not implement such features?
Thanks to.

Answer 1

Unfortunately, it is not possible to play a recording in a line using the standard Android APIs.
People as soon as they do not go out of their way to lose something in a line. Some guys even emulated a bluetooth headset, just to play a pre-recorded message on Android.
In general, it is possible, but wildly difficult.
And there is nothing complicated in recording from the line of conversation. This is done through standard Android APIs.

It is easy to make an incoming call interceptor, just make a receiver for an event in your application and that's it, and then everything your heart desires. The conversation is just sending data to the court through some kind of socket, so just shove your answering machine record into it and that's it. Unfortunately, I can’t say how the standard dialer is implemented
