最近我在Google Play控制台遇到了一个崩溃问题。

设备：Redmi K20 Pro

Android版本：10

我在Android源代码中找不到这部分代码（看起来是小米的修改）

我在React-Native社区发现同样的问题。

有什么解决方法吗？

更新：我在完全本机应用程序上遇到了此崩溃，没有任何跨平台框架。

我也是！目前还没有解决方案，而且Facebook已经将此问题标记为已解决。 - Manoj Perumarath

也许这就是他们回答那个问题的地方。 https://xiaomi.eu/community/threads/xiaomi-android-10-crashes-when-typing-in-an-email-address.56363/ - Tobias Reich

我有同样的问题。我还没有找到解决办法... - Vergiliy

Answer 1

这个崩溃来自于操作系统，实际上，小米制作了一个定制版的安卓系统，在版本10上的修改导致了这个崩溃。有一个解决方案，将caretHidden 标志传递为true值，此问题将消失：

<TextInput
  caretHidden={true}
  ...

我们可以稍微改进一下：

<TextInput
  caretHidden
  ...

Answer 2

我找到了一个适用于本地Android开发者的解决方案。我相信你在editText中使用了inputType作为“textEmailAddress”，只需将其更改为以下内容：

android:inputType="textNoSuggestions|textEmailAddress"

- Pravesh Singh

Answer 3

昨天我也遇到了同样的问题。所以，我花了一些时间才发现，如果在电子邮件输入框中键入一个 . （点），然后清除它，之后再键入电子邮件，应用程序就不会崩溃了。因此，这是另一种解决方法，不需要隐藏插入符号，并且在我的 Redmi 9 上仍然有效。

const [email, setEmail] = useState(".");

useEffect(() => {
  setTimeout(() => {
    setEmail("");
  }, 1);
}, []);
