Question

Up to Android 7.1 it was possible to end an incoming call by using the ITelephony.endCall() method and giving your app the permissions

Answer 1

Changed App Target and Compile level to 28.

And following permissions.

Add the following code on onCallStateChanged method of MyPhoneStateListener class.

public void endCall() {
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.P) {
            TelecomManager tm = (TelecomManager) mcontext.getSystemService(Context.TELECOM_SERVICE);
            if (tm != null) {
                boolean success = tm.endCall();
            }
            // success == true if call was terminated.
        } else {
            if (mcontext != null) {
                TelephonyManager telephony = (TelephonyManager) mcontext
                        .getSystemService(Context.TELEPHONY_SERVICE);
                try {
                    Class c = Class.forName(telephony.getClass().getName());
                    Method m = c.getDeclaredMethod("getITelephony");
                    m.setAccessible(true);
                    telephonyService = (ITelephony) m.invoke(telephony);
                    // telephonyService.silenceRinger();
                    telephonyService.endCall();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }
