The Cortex XDR agent app for Android prevents known malware from running on your Android endpoints. The Cortex XDR agent app enforces your organization’s security policy as defined in Cortex XDR. The security policy determines whether to block known malware and unknown files (recommended), uploads unknown files for in-depth inspection and analysis, treats grayware as malware, and performs local analysis to determine the likelihood that an unknown file is malware. You can also add trusted signers to the Allow List to enable unknown apps that are signed to run before Cortex XDR receives an official verdict for the app. In addition, when a device user shares a URL with the Cortex XDR agent, the Cortex XDR agent app inspects it, and provides an informative analysis of the URL, with details such as verdict, risk level, and the category associated with the URL. We strongly recommend that you always update your Android devices with the latest version of the Cortex XDR agent app. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-agent-android-guide/9.3/cortex-xdr-agent-app-for-android.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
