GeckoView App

simply integrated geckoview, a firefox webview component.

How to use

1. create a GeckoConfigurer object, and use addExtensionDependency to add a component that you want to call through web application. If you not pass a name for the dependency, then lower case of the first letter of class name will be used. Which name will be used in later.

2. write your own function to export to the website. the function defines the shape that you want web to call it; inside the function, pass a NativeMessage object defined at type.d.js to invoke the callNative function thus send the message to the native.

3. in NativeMessage class, there's some parameters that you need attention.

   • extensionName: this is the name of dependencies that you added by GeckoConfigurer, native message handler use this to identify which dependency would be used.
   • action: after use extensionName to find the specific extension, then the name of method as same as action will be invoked.
   • data: pass this data to the action. support named parameters or indexed parameters. the first use JSON object carrier the arguments, and the last use JSON array. In additionally, if only one argument needed by the action, either entire JSON object or the first element of JSON array will be used.

4. define your own native method. method arguments is converted by Jackson ObjectMapper, so all ObjectMapper compatible type should be fine. besides, the org.json.JSONObject and org.json.JSONArray is treated as special, you can directly use them are method arguments.
