每当我在保持模拟器运行的同时运行react-native run-android时，我都会收到此错误。react-native run-ios完全正常。

我正在尝试在我的 firstore 数据库中保存使用 twitter api 检索到的多个推文对象，但出现此错误：

错误：3 INVALID_ARGUMENT：无法在数组值中转换数组值

下面是示例JSON对象：所有推文对象都与此类似

我正在尝试安装 rn-push-notifications，我需要 google play services 版本和 firebase 版本。你能帮我一下吗？

我希望运行一个根据我的云功能中的每个用户运行的调度程序，而不是为所有用户同时运行的通用调度程序。

例如，如果用户 A 执行某个操作，则仅为用户 A 启动调度程序（例如，每 30 分钟一次），而不为其他用户启动。\n但用户 B 也会执行相同的操作，并在不同时间为自己启动调度程序。

Now UserA\xe2\x80\x99s and UserB\xe2\x80\x99s scheduler could be running at different times but same intervals(30 mins)

How can I create such a function?\nHelp would be very much appreciated.

我正在创建一个社交提要，我想在其中无限滚动，使用 firebase 分页，但即使我的 firestore 数据库中有很多不同的数据，查询每次都返回相同的内容。

这是我的初始查询：

const getThreads = async () => {
    try {
      setLoading(true);
      const ref = firestore()
        .collection('Discover')
        .orderBy('rank', 'desc')
        .limit(10);

      let docSnaps = await ref.get();

      if (docSnaps.empty !== true) {
        let docData = docSnaps.docs.map(document => {
          return {
            data: document.data(),
            id: document.id,
          };
        });
        setLastVisible(docData[docData.length - 1].id);
        setThreads(docData); //Setting the data to display in UI
      }
      setLoading(false);
    } catch (e) {
      setLoading(false);
      console.log(e);
      Alert.alert(
        'Oops! Looks like something went wrong',
        'Please try again later',
        [{text: 'OK'}], …
