Telephonymanager.EXTRA_INCOMING_NUMBER is deprecated in API level 29

问题

I am in situation where I need to identify incoming call phone number in Android but when using TelephonyManager.EXTRA_INCOMING_NUMBER android studio warning EXTRA_INCOMING_NUMBER is deprecated.I gone through the developers.android.com, it shows apps performing call screening should use the CallScreeningService API instead. But I can't figure out how to use CallScreeningService to get incoming call phone number. Anyone can help me?

As @Saurabh said, the new way to screen calls is through the CallScreeningService. However, for the service to work on Android Q and up, the user needs to set your app as the default caller ID & spam app (which is done by using the new RoleManager class)

 <service android:name="com.example.ScreeningService"
     android:permission="android.permission.BIND_SCREENING_SERVICE">
     <intent-filter>
         <action android:name="android.telecom.CallScreeningService"/>
     </intent-filter>
 </service>

Create you service class:

 @RequiresApi(api = Build.VERSION_CODES.N)
 class ScreeningService : CallScreeningService() {

     override fun onScreenCall(details: Details) {
         //code here
     }

 }

Request the screening role from the user in your main activity (or where ever you see as fit):

 @RequiresApi(Build.VERSION_CODES.Q)
 private fun requestScreeningRole(){
     val roleManager = getSystemService(Context.ROLE_SERVICE) as RoleManager
     val isHeld = roleManager.isRoleHeld(RoleManager.ROLE_CALL_SCREENING)
     if(!isHeld){
         //ask the user to set your app as the default screening app
         val intent = roleManager.createRequestRoleIntent(RoleManager.ROLE_CALL_SCREENING)
         startActivityForResult(intent, 123)
     } else {
         //you are already the default screening app!
     }
 }

Catch the user's response:

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
         super.onActivityResult(requestCode, resultCode, data)
         when (requestCode) {
             123 -> {
                 if (resultCode == Activity.RESULT_OK) {
                     //The user set you as the default screening app!
                 } else {
                     //the user didn't set you as the default screening app...
                 }
             }
             else -> {}
         }
     }

Apologies for using a hard coded request code >.<

Create a CallScreeningService like this:

class ScreeningService : CallScreeningService() {

    override fun onScreenCall(callDetails: Call.Details) {
        val phoneNumber = callDetails.handle.schemeSpecificPart
        // Do stuff with phone number
    }
}

And register this service in your AndroidManifest.xml:

<service android:name="your.package.ScreeningService"
         android:permission="android.permission.BIND_SCREENING_SERVICE">
     <intent-filter>
         <action android:name="android.telecom.CallScreeningService"/>
     </intent-filter>
</service>
