### Example ProGuard Rule for WebView JavaScript Interface

Source: https://github.com/yixia/vitamiobundle/blob/master/vitamio-sample/proguard-project.txt

This ProGuard rule demonstrates how to prevent obfuscation of public members within a JavaScript interface class used by Android's WebView. This is crucial to ensure that JavaScript can correctly call methods on the Java object.

```ProGuard
-keepclassmembers class fqcn.of.javascript.interface.for.webview {
   public *;
}
```

### Example ProGuard Rule for WebView JavaScript Interface

Source: https://github.com/yixia/vitamiobundle/blob/master/vitamio/proguard-project.txt

This commented-out ProGuard rule demonstrates how to prevent obfuscation of a JavaScript interface class used with Android's WebView. If your project exposes Java methods to JavaScript via `addJavascriptInterface()`, you must keep the interface class and its public members to ensure JavaScript calls can correctly invoke the corresponding Java methods.

```ProGuard
-keepclassmembers class fqcn.of.javascript.interface.for.webview {
   public *;
}
```

### Keeping Vitamio Library Classes from Obfuscation

Source: https://github.com/yixia/vitamiobundle/blob/master/vitamio/proguard-project.txt

These ProGuard rules explicitly instruct the ProGuard tool to keep all public members of specified `io.vov.vitamio` classes. This is crucial for preventing runtime errors that might occur if these classes or their members are obfuscated, removed, or optimized by ProGuard, as the Vitamio library relies on specific class and method names for reflection or direct access.

```ProGuard
-keep public class io.vov.vitamio.MediaPlayer { *; }
-keep public class io.vov.vitamio.IMediaScannerService { *; }
-keep public class io.vov.vitamio.MediaScanner { *; }
-keep public class io.vov.vitamio.MediaScannerClient { *; }
-keep public class io.vov.vitamio.VitamioLicense { *; }
-keep public class io.vov.vitamio.Vitamio { *; }
-keep public class io.vov.vitamio.MediaMetadataRetriever { *; }
```
