Android Question Replace default dialer APP

[rcla]

I want to create an application that overrides the default dialer.

I have searched the forum, in the tests, when making a phone call,
it always keeps showing the dialer.

I found this information very useful:
replace-default-phone-app

I tested the application of the author arekolek and it works great.

Source Code:
Kotlin version: Simple Phone
Java version: simple phone dialer

I have already changed the manifest with some of those lines:

AddActivityText(Main,
            <intent-filter>
                <!-- Handle links from other applications -->
                <action android:name="android.intent.action.VIEW" />
                <action android:name="android.intent.action.DIAL" />
                <!-- Populate the system chooser -->
                <category android:name="android.intent.category.DEFAULT" />
                <!-- Handle links in browsers -->
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="tel" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.DIAL" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>)

To make a phone call I have used:

    Dim MPhones As PhoneCalls
    StartActivity(MPhones.Call("123456789"))

or

    Dim Pha As Intent
    Pha.Initialize(Pha.ACTION_CALL, "tel:123456789")
    StartActivity(Pha)

or

    Dim in As Intent
    in.Initialize("android.intent.action.CALL","tel:123456789")
    StartActivity(in)

But all that concerns "InCallService", I don't know how to translate it to B4A.

I appreciate if someone can help me.

The service implementation is explained here: https://developer.android.com/reference/android/telecom/InCallService

I don't think that anyone has already implemented in B4A. It does require some Java / native Android knowledge. The most relevant example is: https://www.b4x.com/android/forum/threads/example-of-extends-in-service.74880/

Thanks for the guidance.


I have used SLC, to try to make the respective wrapper for B4A, with these two files:
OngoingCall.java
CallService.java

My knowledge of Java is very scarce ... and I have been trying for several days without any success.
