Telephonymanager.EXTRA_INCOMING_NUMBER is deprecated in API level 29

Question

I am in situation where I need to identify incoming call phone number in Android but when using TelephonyManager.EXTRA_INCOMING_NUMBER android studio wa

Answer 1

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>

Answer 2

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)

1. Register your screening service:

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

2. Create you service class:

    @RequiresApi(api = Build.VERSION_CODES.N)
    class ScreeningService : CallScreeningService() {
   
        override fun onScreenCall(details: Details) {
            //code here
        }
   
    }
   

3. 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!
        }
    }
   

4. 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 >.<
