# Mobile Consent - Android Quickstart (/docs/consent-management/mobile-consent/android/android-quick-start)

## Overview [#overview]

We provide an Android library hosted on Maven Central to minimize the modifications needed by our customers in their applications. The library, `com.transcend.webview:webview:VERSION`, contains the majority of the logic for saving TCF-related data and interacting with the organization-specific `mobile/bridge.js` which handles displaying the UI and passing information between the WebView and the SDK. Below is a list of steps necessary to utilize the Transcend WebView library:

### ProGuard rules [#proguard-rules]

To ensure that the classes and members of the `io.transcend.webview` package are not obfuscated or removed by ProGuard, it's recommended to include the following ProGuard rule in your ProGuard configuration file (`proguard-rules.pro`):

```groovy
-keep class io.transcend.webview.** { *; }
```
