android - getZoom 和 getVisibleBounds 方法永远不会在 @mapbox/react-native-mapbox-gl Android 中解析

Question

问题

使用 this.map refereance @mapbox/react-native-mapbox-gl npm 模块获取 mapbox 边界坐标时出现问题。我使用了 getVisibleBounds() 方法，但它无论如何都不会解析 promise。

try {
      let bounds = await this.map.getVisibleBounds();

      console.log("Bounds : ", bounds);
    } catch (err) {
       console.log("Error : ", err);
     }

我在 Android 的 React-Native App 中使用了以下依赖项。

"@mapbox/react-native-mapbox-gl": "6.1.2-beta2"

"react": "16.3.1"

"react-native": "0.55.4"

既不会打印 Bounds 也不会打印 Error

请帮我解决这个问题

gitgub mapbox repo 上也有 issue raise，但他们也没有回复这个问题。您可以查看以下链接了解更多详情。

这可能不是问题所在，但是，您是否在 Android Studio 的 logcat 控制台中得到了这个？

似乎事件是在桥被摧毁后发出的。如果您正在调试，请尝试关闭调试器控制台 (React Native Debugger)，禁用 Live Reload/Hot Reload > Rebuild。

似乎有些事件在调试过程中被杀死，请在此处查看 mapbox 问题:
