Question

我正在使用react-native编写适用于Android和iOS的应用程序。 iOS版本可完美运行，但每次尝试调用AsyncStorage函数时，Android版本都会崩溃。

启动我的应用程序时，它会检查设备上是否存储了一些用户信息。它在这里使用此功能：

static async getActiveUser() {
    return null;
    try {
      let value = await AsyncStorage.getItem('@UserStore:activeUser');
      if (value !== null){
        return JSON.parse(value);
      } else {
        return null;
      }
    } catch (error) {
      console.log(error);
    }
  }

正如我之前所说，iOS版本运行完美。当我在Android上运行此代码时，它在以下行崩溃：

let value = await AsyncStorage.getItem('@UserStore:activeUser');

在getActiveUser()函数内部调用函数componentDidMount。

我正在寻找解决方案的时间！！有人可以帮忙吗？非常感谢！

您的日志，

07-16 13:16:49.098 7154-7205/com.mblum.cvjm E/unknown:ViewManager: Error while updating prop color 您的AsyncStorage中没有问题，因为日志清楚地表明了这一点。

一些提示：

如果您曾经认为AsyncStorage不能很好地响应，那通常意味着您那里的数据类型错误。因此，请始终尝试AsyncStorage.setItem(JSON.stringify('token')); （仅用于调试目的）
