telephony

Looking for a way to get a list of telephone area codes for a given latitude and longitude (and if necessary a given intl. code.) Note, I'm not talking about international dialing prefixes but the area codes within them. For example, Denver Colorado is covered by the area codes 303 and 720. It's at 39.739 -104.985 and is in NANP 1. So given 39.739,-104.985,1 I'd like to get back [303,720]. Libraries, web services, DB's, or raw data that needs to be parsed into a DB, e.g., a web page of shape points, are all fine and the more global coverage the better, but just NANP 1 would be a great help.

i'm trying to make a phone call from the app and I want it to return back to the app after the call i asked that question in this forum but i didn't understand the answer How to make a phone call in android and come back to my activity when the call is done? public void call() { try { Intent callIntent = new Intent(Intent.ACTION_CALL); callIntent.setData(Uri.parse("tel:048598077")); getContext().startActivity(callIntent); } catch (ActivityNotFoundException activityException) { Log.e("dialing-example", "Call failed", activityException);} finally { EndCallListener callListener = new

I have been learning more about WebRTC, SIP and PSTN and how they work together especially the ability to receive phone calls in browser. I have spent some time on Twilio's website and I like the way they are able to make you receive a phone call From PSTN to your browser. I want to understand how they are able to let someone call a normal PSTN phone number and the call is directed to web browser. I bumped into this question and got some little understanding but there are some things that are still missing for me. To help clarify my question, let us take the following scenario: 1st Part Let's

I wanted to disable features related to CALL and SMS in my application based on whether SIM hardware is present or not. Now a beginners approach towards this will be checking the Phone type using : if (telephonyManager1.getPhoneType() == TelephonyManager.PHONE_TYPE_NONE) If true then its supported. Everything was fine until i came across Sony Tablet S which has a SIM support only for Data and Messaging. No voice support. So for this device i need to disable only CALL feature but continue with SMS support. Sony tablet returns TelephonyManager.PHONE_TYPE_NONE so i can`t use the above methods.

I've downloaded the entire source code for the master branch from https://android.googlesource.com/platform/frameworks/base/+/master , and am trying to decipher the chain of events on an incoming call. I assume that the ACTION_ANSWER intent is started but beyond that don't know what happens before or after. Can anyone help? Let's begin by looking at CallNotifier : /** * Phone app module that listens for phone state changes and various other * events from the telephony layer, and triggers any resulting UI behavior * (like starting the Ringer and Incoming Call UI, playing in-call tones, *

Is there any way to detect outgoing call is successfully received or answered ? I am using Intent.ACTION_CALL for dialing a call and PhoneCallListener to find the state of a call when outgoing call answered but I couldn't have been achieving this. Is this possible in android ? Mohammad Qandeel After deeply working on this issue, I reached this conclusion: PhoneStateListener won't work for outgoing calls, it calls OFFHOOK instead of RINGING and OFFHOOK is never called on ANSWER. Using NotificationListenerService , you can listen to posted notifications related to outgoing calls. You can do
