React Native应用程序在返回前台时滞后

Question

在将React Native应用程序放到后台并将其留在后台任何时间长度后，我得到了一个延迟（大约10秒）的延迟。

整个应用程序都被冻结了。

可能导致这种情况的原因是什么？调试和隔离问题的最佳方法是什么？

我的package.json是：

{
  "name": "MyApp",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start"
  },
