+## Description
+
+Hybrid application that is deployed on an Android device cannot do any HTTP/HTTPS requests.
+
+## Error Message
+
+Failed to load resource: the server responded with a status of 404 (Not Found) 
+
+## Cause
+
+{{site.ac}} 4.0 and above incorporates the {{site.ac}} domain whitelisting, a security model which provides a configurable security policy to define which external sites may be accessed. For Android, this policy is implemented by the [{{site.ac}} Whitelist Plugin](https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-whitelist/). If the plugin is not enabled in the project, any HTTP/HTTPS request will respond with a status of 404 (Not Found).
+
+## Solution
+
+To enable the {{site.ac}} Whitelist Plugin and allow the HTTP/HTTPS requests, complete the following steps:
+
+1. Open the project in your preferred AppBuilder client.
+1. Open project **Properties**.
+1. Open the **Plugins** tab.
+1. In the **Core Plugins** section, locate the **Whitelist** plugin.
+1. **Enable** the **Whitelist** plugin for the project.
+1. **Rebuild** the application and then **deploy** it on the Android device.
