参考文档：
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' 使用方式：
控件：
