Creating custom android dialer

Question

I am working on the new phone app for Android. Obviously it needs to make and receive phone calls.

My first problem is how to place a phone call from the app without invoking System default dialer. Making calls using Intent is very easy. However when I try to place a call without using Intent then that's entirely different ball of wax.

It seems that I need to use android.telephony but I can't find any good resources that could tell me where to start. Simple tutorial would be nice.

If you could point me to a resource that would help me that will be really appreciated.

Example is using Intent to pass phone number to the existing Dialer. That is exactly what I don't want to do. — svager, Mar 29 '15 at 01:50

From Android 10 onwards the only way to handle phone calls is by using the InCallService APIs. I have made a basic dialer app that explains basics of how to handle calls as a default dialer app. https://github.com/adnan-creator/java-custom-dialer

@PatrickKlein It's a whole app, there isn't any particular code that would specifically be helpful. – Adnan Arshad Nov 13 '20 at 21:00

Create an app that responds to Intent.ACTION_DIAL. In the AndroidManifest.xml you need to add the following to that Activity:

<intent-filter>
    <action android:name="android.intent.action.DIAL" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>
