geckoview版本
引入文档（有坑 下面会给出正确引入方式）
官方示例代码1
官方示例代码2

参考了两位大神的博客和demo：

GeckoView js交互实现
geckoview-jsdemo

引入方式：

        maven {             url "https://maven.mozilla.org/maven2/"         } 

    compileOptions {         sourceCompatibility JavaVersion.VERSION_1_8         targetCompatibility JavaVersion.VERSION_1_8     } 

implementation 'org.mozilla.geckoview:geckoview-arm64-v8a:111.0.20230309232128'
