The docs state that this service performs call identification to
display a user-interface of their choosing which contains identifying information for a call.
but i cannot find any method to do this.
I set up a call screening service overriding the onScreenCall method and I am able to get the incoming call phone number and get a caller id (if it exists in my database) but cant get it to show on the call ui

In the following link:
https://developer.android.com/guide/topics/connectivity/telecom/selfManaged
I see the quote
Use the addNewIncomingCall(PhoneAccountHandle, Bundle) method to
inform the telecom subsystem about the new incoming call.
This makes no sense to me. How is my app notifying the Telecom subsystem about incoming calls? Isn't it the other way? It seems like a new call enters the device and the Telecom framework routes it to an app to handle the logic, e.g. my application. How would my app ever know about an incoming call before the Telecom system? What mechanism would notify my application of an incoming call? What service or activity would even call the addNewIncomingCall method?
Now, my intuition says I need to use a receiver to listen for an incoming call by detecting a change in the phone state. However, the following link says that is not the proper way.
https://developer.android.com/guide/topics/connectivity/telecom
That instead you should be using the inCallService and connectionService, which are services I am currently using.
Traditionally, standalone calling apps have relied on listening to the
phone state to try to determine when other calls are taking place.
This is problematic as the phone state does not take into account
other calling apps the user may have installed. Using a self-managed
ConnectionService helps you ensure that your app will interoperate not
only with native telephony calling on the device, but also other
standalone calling apps implementing this API. The Self-Managed
ConnectionService API also manages audio routing and focus for you.
I'm just not sure how they fit into the bigger picture of receiving incoming calls. All the documentation says you don't need to implement the inCallService if you don't want your own custom user interface. But I don't see how the connectionService gets a reference to the Call object otherwise.
Does anybody have a good flow chart or other graphical representation of how the Telecom subsystem functions at a high level? How the callbacks work in the framework?
Ideally I want to use the default dialer interface, dial pads, everything but be notified first of an incoming call and programmatically silently reject the call or pass it through to the default dialer.
Thanks!
I just want to know if when an outgoing call ends, we can differentiate and know if it was due to normal hangup (normal call end), or call end due to disconnection (loss of signal, network congestion, or any reason from the carrier)
There are two main interfaces to call events depending on whether you are using the standard call app provided or are implementing your own user interface to manage calls.
If you are using the standard call service then you limited to whatever callbacks the Android telephony manager propvides:
https://developer.android.com/reference/android/telephony/TelephonyManager.html
This is a fairly limited set of events and I don't think will give you what you are looking for. It will allow you detect that the phone has gone from off hook to idle state, but not why.
If you are implementing the user interface yourself for call control, then you have access to a rusher set of events via the InCallService:
https://developer.android.com/reference/android/telecom/InCallService.html
This provides more information in callbacks but it still does not give a 'disconnect reason' for calls, AFAIK.
Note also that to use the InCallService your app must be registered as the default phone app.
How to get call log history for individual contacts, incoming calls and out going calls separately and call log history for particular date in calender programmatically?
Please refer to my answer provided on this post for accessing call log history. You can get the outgoing and incoming call logs and use them accordingly
i'm developing an android app that retrieves the call log and store it in a text file. I'm using the ContentObserver to observe for the changes and fetch the updated entry once there is a change. I'm able to fetch the entries correctly if i get a miss call, incoming call and make an outgoing call by dialing the number from the phone book. If i make an outgoing call by clicking the number from the call log, the onChange() method is called thrice. The onChange() is called once i select the name from the call log, before making a call, such that retrieving the previous event once. Once the call is made, the outgoing event is retrieved twice, totally making three entries. Please do suggest me a solution.
Thanks!
In which URI did u register the observer. Is it android.provider.CallLog.Calls.CONTENT_URI? If so then the onChange() method will be called only once.
Also, relying in content providers is not a good idea. Refer http://android-developers.blogspot.com/2010/05/be-careful-with-content-providers.html. Instead of using content observers you can try using broadcast receiver with actions
android.intent.action.PHONE_STATE
android.intent.action.NEW_OUTGOING_CALL
I am developing an application in which I am storing call log details from CallLog provider.
Android stores call logs in a database and I am copying new rows from that database.
Now I want to copy call details when the user ends a call. For that I have used the PhoneStateListener with which I listen for state ringing, off hook and idle mode
but after the call is ended the idle method calls more than once, so I cannot use that.
Second I used ContentObserver for call log table and it gives me onChanged event when Android inserts call details in it and at that time I copy those details into my database.
Is it that the proper way to use ContentObserver?
Is there any other way to get details of new calls which is just ended?
That sounds like a valid use of the ContentObserver. A prior attempt at this is here: Intent to be fired when a call ends?.
I'd suggest you go with the idle method and simply track state in a database or variable or preference (so whenever the phone goes from OFFHOOK to IDLE you know the call ended, but when it goes from IDLE to IDLE then you do nothing).
Good luck.
