嗨，我正在使用sms_autofill 1.2.3自动填充 OTP。我的颤振应用程序能够自动读取 OTP，但并非总是如此，比如当我进行一些更改并进行热重载时，甚至在再次运行颤振运行后，有时它不会读取代码我是否遗漏了什么？我正在使用 sms_autofill 1.2.3 自动填充 OTP。我的颤振应用程序能够自动读取 OTP，但并非总是如此，比如当我进行一些更改并进行热重载时，甚至在再次运行颤振运行后，有时它不会读取代码我是否遗漏了什么？

如果您在 Android 上进行测试，请确保您已在消息末尾添加哈希或签名代码，以识别插件文档中提到的您的应用程序。哈希应该对应于您的应用程序的密钥库签名。
