# Why Push Notifications Do Not Work in the Killed State on Android?

> Fix push notifications not working when the Android app is killed. Covers correct SDK initialization for native and Hybrid SDK integrations.

## Problem

Push notifications work when the app is in the foreground or background but not when the app is killed. This issue occurs specifically with Hybrid SDK integrations.

<Warning>
  This is a known limitation when using ReactNative methods to pass the push payload to MoEngage.
</Warning>

## Explanation

* The most common reason is that the SDK is not initialized correctly. For more details, refer to the [SDK Initialization](https://www.moengage.com/docs/developer-guide/android-sdk/sdk-integration/basic-integration/sdk-initialization) documentation.

## Solution

* If you use ReactNative methods to pass the push payload, it is recommended to allow MoEngage to handle the push payload or use Android native methods to pass it to the MoEngage SDK.
* If the SDK is not initialized,
  * Initialize the MoEngage SDK in the Application class's *onCreate()* method.
  * Ensure the SDK is initialized on the main thread inside *onCreate()* and not on a worker thread.
