# Deregister a Mobile Device for Push Notifications 

You can deregister a device that was registered for Catalyst Android push notifications by passing the required parameters to the `deregisterNotification()` method as shown below.

```bash
val app = ZCatalystApp.getInstance()
app.deregisterNotification (device_token,"bundleID",
 "appID", test_device_boolean, {
                Log.i("Unregister","App unregistered successfully");

            }, {
                Log.i("Unregister","App unregisteration failed");
            })

```

**Parameters:**
    
* `device_token`: The device token obtained from [FCM for your app](https://docs.catalyst.zoho.com/en/cloud-scale/help/push-notifications/android/#configure-and-enroll-for-android-push-notifications).

* `bundleID`: The Android app's bundle ID that you configured while [registering the app with Catalyst](https://docs.catalyst.zoho.com/en/sdk/android/v2/setup/) as well as in Firebase.

* `appID`: The app ID generated by Catalyst for your app in Push Notifications. You can find this in the *Android* section of Push Notifications in your Catalyst console.

* `test_device_boolean`: The value is set to `true` for test devices, and set to `false` for production devices
