当我按两次主页按钮将应用程序发送到后台时，或者每当我传递到另一个应用程序时，应用程序就会崩溃。您可以观看下面的视频；

解决方案

基本上是由 Google Analytics 插件引起的问题。我切换到 Fribase Analytics 并解决了问题!

Answer 1

您需要更改应用程序状态并确保没有正在运行的进程，例如不会在后台运行的推送通知。尝试发布正在运行的代码，我会尝试更改我的答案。

getInitialState: function() {
  return {
    currentAppState: AppState.currentState,
  };
},
componentDidMount: function() {
  AppState.addEventListener('change', this._handleAppStateChange);
},
componentWillUnmount: function() {
  AppState.removeEventListener('change', this._handleAppStateChange);
},
_handleAppStateChange: function(currentAppState) {
  this.setState({ currentAppState, });
},
render: function() {
  return (
    <Text>Current state is: {this.state.currentAppState}</Text>
  );
},
