Android OTP（令牌）应自动从邮件中读取
我正在开发一个Android应用程序，其中服务器发送一个OTP，用户需要在应用程序中输入这个OTP，才能注册我的应用程序。我想要的是，我的应用程序应该能够自动读取服务器发送的OTP。我怎样才能做到这一点？在这方面的任何帮助或指导都将不胜感激。我实施了类似的措施。但是，当消息传入时，我只检索六位代码，将其捆绑在一个intent中，并将其发送给需要它的活动或片段，并验证代码。该示例向您展示了获取sms的方法。查看下面的代码，了解如何使用LocalBrodcastManager发送邮件，如果您的邮件包含更多文本，例如问候语，请将其标准化，以更好地帮助您。例如，“您的验证码是：84HG73”您可以创建一个regex模式，如Android OTP（令牌）应自动从邮件中读取,android,one-time-password,Android,One Time Password,我正在开发一个Android应用程序，其中服务器发送一个OTP，用户需要在应用程序中输入这个OTP，才能注册我的应用程序。我想要的是，我的应用程序应该能够自动读取服务器发送的OTP。我怎样才能做到这一点？在这方面的任何帮助或指导都将不胜感激。我实施了类似的措施。但是，当消息传入时，我只检索六位代码，将其捆绑在一个intent中，并将其发送给需要它的活动或片段，并验证代码。该示例向您展示了获取sms的方法。查看下面的代码，了解如何使用LocalBrodcastManager发送邮件，如果您的邮件包

这有帮助吗。我通过使用回调做得更好我实现了类似的功能。但是，当消息传入时，我只检索六位代码，将其捆绑在一个intent中，并将其发送给需要它的活动或片段，并验证代码。该示例向您展示了获取sms的方法。查看下面的代码，了解如何使用LocalBrodcastManager发送邮件，如果您的邮件包含更多文本，例如问候语，请将其标准化，以更好地帮助您。例如，“您的验证码是：84HG73”您可以创建一个regex模式，如

您可以尝试使用一个简单的库 通过gradle安装并添加权限后，在onCreate activity之类的方法中启动SmsVerifyCatcher：
smsVerifyCatcher = new SmsVerifyCatcher(this, new OnSmsCatchListener<String>() {
@Override
public void onSmsCatch(String message) {
String code = parseCode(message);//Parse verification code
etCode.setText(code);//set code in edit text
//then you can send verification code to server
}
});

我建议您不要使用任何第三方库从SMS收件箱自动获取OTP。 如果您对广播接收器及其工作原理有基本了解，则可以轻松完成此任务。 请尝试以下方法： 步骤1）创建单一界面，即SmsListner 步骤2）创建单个广播接收器，即SmsReceiver OTP验证活动的布局文件
