How to run a built-in call app when a device gets incoming call in onCallAdded(InCallService) function?

When a phone is ringing ( by an incoming call) If the phone number is a specific number I want to show my custom UI. If It is not, I want to pass it to the (built-in) system call app(Or any other call app is okay).
I should use 'InCallService' and the device set my app as 'a default call app' so that even when the phone screen is locked my custom-UI-activity be shown. The following kotlin source code is my goal.
override fun onCallAdded(call: Call) {
//app should receive a new incoming call via 'onCallAdded'
super.onCallAdded(call)
val phoneNumber = getPhoneNumber(call)
if (isMyTargetNumber(phoneNumber)) {
//show my custom UI
} else {
//run a built-in call app
}
}
The problem that I want to solve is how to run a built-in call app appropriately. I mean I want to complete to wirte the blank of 'else'
else {
//run a built-in call app
}
Apps on the android market like 'truecaller' or 'whosecall' works well the way I want to acheive. I want to make my app such apps. Please help me and advise something to me.

Pepper Robot - How to launch tablet applications through DialogFlow?

I'm trying to incorporate Pepper's built in Android tablet more in DialogFlow interactions. Particularly, my goal is to open applications installed on the tablet itself for people to use while they're talking with Pepper. I'm aware there is a 'j-tablet-browser' app installed on Pepper's end that can let a person browse the tablet like an ordinary Android device, but I would like to take it one step further and directly launch an Android app, like Amazon's Alexa.
The best solution I can up with is:
User says specific utterance (e.g. "Pepper, open Alexa please")
DialogFlow launches the j-tablet-browser behavior
{
"speak": "Sure, just a second",
"action": "startApp",
"action_parameters": {
"appId": "j-tablet-browser/."
}
}
User navigates the Android menu manually to tap the Alexa icon
My ideal goal is to make the process seamless:
User says specific utterance (e.g. "Pepper, open Alexa please")
DialogFlow launches the Alexa app installed on the Android tablet
Does anyone have an idea how this could be done?

This is quite a broad question so I'll try and focus on the specifics for launching an app with a Dialogflow chatbot. If you don't already have a QiSDK Dialogflow chatbot running on Pepper, there is a good tutorial here which details the full process. If you already have a chatbot implemented I hope the below steps are general enough for you to apply to your project.
This chatbot only returns text results for Pepper to say, so you'll need to make some modifications to allow particular actions to be launched.
Modifying DialogflowDataSource
Step 2 on this page of the tutorial details how to send a text query to Dialogflow and get a text response. You'll want to modify it to return the full reponse object (including actions), not just the text. Define a new function called detectIntentFullResponse for example.
// Change this
return response.queryResult.fulfillmentText
// to this
return response.queryResult
Modifying DialogflowChatbot
Step 2 on this page shows how to implement a QiSDK Chatbot. Add some logic to check for actions in the replyTo function.
var response: DetectIntentResponse? = null
// ...
response = dataSource.detectIntentFullResponse(input, dialogflowSessionId, language)
// ...
return if (reponse.action != null) {
StandardReplyReaction(
ActionReaction(qiContext, response), ReplyPriority.NORMAL
)
} else if (reponse.answer != null) {
StandardReplyReaction(
SimpleSayReaction(qiContext, reponse.answer), ReplyPriority.NORMAL
)
} else {
StandardReplyReaction(
EmptyChatbotReaction(qiContext), ReplyPriority.FALLBACK
)
}
Now make a new Class, ActionReaction. Note that the below is incomplete, but should serve as an example of how you can determine which action to run (if you want others). Look at SimpleSayReaction for more implementation details.
class ActionReaction internal constructor(context: QiContext, private val response: DetectIntentResponse) :
BaseChatbotReaction(context) {
override fun runWith(speechEngine: SpeechEngine) {
if (response.action == "launch-app") {
var appID = response.parameters.app.toString()
// launch app at appID
}
}
}
As for launching the app, various approaches are detailed in other questions, such as here. It is possible to extend this approach to do other actions, such as running or retrieving online data.

Identify if the android device is one of the samsung edge devices

I have a requirement in which I have to figure out if my android app is running on one of the samsung edge devices or its a regular android phone. Accordingly my ui would update. All i could gather is that the device name has a substring edge in it. Can someone suggest me a a a better way to do this ?

For samsung device's, take a look at the Samsung programming guide for Edge, in page 10 :
initialize() initializes Look. You need to initialize the Look package
before you can use it. If the device does not support Look,
SsdkUnsupportedException exception is thrown.
If an SsdkUnsupportedException exception is thrown, check the
exception message type using SsdkUnsupportedException.getType(). The
following two types of exception messages are defined in the Slook
class:
VENDOR_NOT_SUPPORTED: The device is not a Samsung device.
DEVICE_NOT_SUPPORTED: The device does not support the Look package.
So you can do this:
Slook slook = new Slook();
try {
slook.initialize(this); // it is a edge
} catch(SsdkUnsupportedException e)
{
// it is not an edge
}

I am trying to make an application that will make phone calls one after another from the list of number

I am developing an application for my friend who is in sales, this application will make phone calls one after another, as soon as one phone call gets disconnected, it will automatically make call to another number from the list. This list can be read from and xml data source or json or mongodb or even from excel sheet.
This could be an ios app that reads data from an end point and stores them and can initiate the call at any point and it wont stop until all the calls are made.
Next call will be made only after the first call has been finished.
I am thinking about using node based web app using google voice to trigger the chain.
I've no experience with ios / android apis but Im willing to work on that if it's a viable thing on that platform.
Note: what we're trying to avoid is whole process of
looking up the phone number.
touch hangup and then click for another phone number.
It should self trigger the next call as soon as current call gets disconnected.
Also we're trying to avoid any paid services like twillo.
Thanks in advance :)

for IOS, you could use CTCallCenter
self.callCenter = [[CTCallCenter alloc] init];
self.callCenter.callEventHandler = ^(CTCall *call){
if ([call.callState isEqualToString: CTCallStateConnected])
{
//NSLog(#"call stopped");
}
else if ([call.callState isEqualToString: CTCallStateDialing])
{
}
else if ([call.callState isEqualToString: CTCallStateDisconnected])
{
//NSLog(#"call played");
}
else if ([call.callState isEqualToString: CTCallStateIncoming])
{
}
};
Download phone list, loop inside phone list, make a call, listening for CTCallCenter and appdelegate's Event, detect user have finish last call, our app active again, then make the next call.
Or you can try in Demo here !

App using Mobile Android GNSK crashes when identifyAlbumAsync() is called before audioProcessStart()

I have being upgrading an application to use the new Mobile Android GNSK but I have noticed that using the new MusicID-Stream is a little bit tricky. If the "identifyAlbumAsync" method get executed before the "audioProcessStart" method(since this need to be executed in a different thread), the application just crashes. In the Gracenote Demo application, the "audioProcessStart" method is continuously running so there is no need to synchronize its execution with the "identifyAlbumAsync" method call. Is it the way it is supposed to be used? It will be convenient if the application didn't crashed at least when the methods are not executed in order. Also in our application, we don't want to have the "audioProcessStart" method continuously like it is done in the demo application. We only want to run the "audioProcessStart" method when the user request identification and when the song playing gets identified , we want to stop the audio processing by calling "audioProcessStop". Is there an easy way to do this? Right now, we are getting the Thread where "identifyAlbumAsync" is running to sleep for 2 seconds in order to make sure that the Thread where the "audioProcessStart" method is supposed to run has time to get executed. Thank you in advance for your prompt response

In the upcoming 1.2 release, IGnMusicIdStreamEvents includes a callback that signals audio-processing has started, and an ID can be synced with this, e.g.:
#Override
public void musicIdStreamProcessingStatusEvent( GnMusicIdStreamProcessingStatus status, IGnCancellable canceller ) {
if (GnMusicIdStreamProcessingStatus.kStatusProcessingAudioStarted.compareTo(status) == 0) {
try {
gnMusicIdStream.identifyAlbumAsync();
} catch (GnException e) { }
}
}

Thanks for the feedback, you're right about this issue. Unfortunately right now sleeping is the best solution. But we are adding support for an explicit sync event in an upcoming release, please stay tuned.
