### Default ProGuard Configuration for Android

Source: https://github.com/comcast/freeflow/blob/master/FreeFlowTestsStub/proguard-project.txt

This snippet provides the default ProGuard configuration structure for Android projects, including instructions on how to add project-specific rules and an example for keeping WebView JavaScript interface members.

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}
```

### Configure ProGuard for WebView JavaScript Interface

Source: https://github.com/comcast/freeflow/blob/master/examples/Artbook/proguard-project.txt

This ProGuard rule prevents obfuscation of JavaScript interface methods used by Android WebView. Uncomment and replace `fqcn.of.javascript.interface.for.webview` with the fully qualified class name of your JavaScript interface class to ensure its public methods are preserved during ProGuard processing.

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

### ProGuard Rule for WebView JavaScript Interface

Source: https://github.com/comcast/freeflow/blob/master/FreeFlowTests/proguard-project.txt

This ProGuard rule is used to prevent the obfuscation or removal of public members within a specified JavaScript interface class that is exposed to an Android WebView. Replace 'fqcn.of.javascript.interface.for.webview' with the actual fully qualified class name of your JavaScript interface.

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

### Configure ProGuard for WebView JavaScript Interfaces

Source: https://github.com/comcast/freeflow/blob/master/FreeFlow/proguard-project.txt

This ProGuard rule prevents obfuscation and removal of public members within a JavaScript interface class used by Android WebView. Replace 'fqcn.of.javascript.interface.for.webview' with the fully qualified class name of your JavaScript interface.

```ProGuard
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}
```

### Keep JavaScript Interface Members in Android WebView with ProGuard

Source: https://github.com/comcast/freeflow/blob/master/examples/PhotoGrid/proguard-project.txt

This ProGuard rule ensures that all public members of a specified JavaScript interface class, used by an Android WebView, are preserved during the obfuscation and optimization process. This is crucial for maintaining proper communication between JavaScript and native Android code.

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