问题 Well, I did a program to make a call to any number of my contact list and it works like a charm. The problem is that I would like to know if the connection has been estabilished (the other person has picked up the phone), and I have not any idea about how to do it. Is there something like an interrupt that can alert me when the connection has been estabilished? 回答1: listen to the broadcast ACTION_PHONE_STATE_CHANGED, for more information check this out here 来源： https://stackoverflow.com

问题 Below is my Java implementation. The idea is to display myUtilString in an edit text in order to see the signal strength in a Hybrid android app while in a WL.NativePage, but I get nothing. I have tested the app on a real device, changing to 2G, 3G and LTE but I don't receive anything. I have implemented a function called onSignalStrengthsChanged , but I cant figure out what is wrong. In LogCat there is nothing of interest; maybe onSignalStrengthsChanged never is fired. package com

问题 I have a completely standard installation of Trixbox with 2 SIP extensions set up on it. Both extensions are Snom 370 SIP phones. I can originate a call from one extension to the other using the following CLI command: originate sip/101 extension 102 This causes the phone on 101 to ring, then when that phone is picked up it dials 102. What I would like is for the phone on 101 to automatically call 102, without 101 waiting to be picked up. Is this something that can be done, or do the SIP
