我使用 Android SafetyNet ReCaptcha 在我的Android应用中显示Google验证码。问题是，当我对其进行测试时，这些复选框永远不会显示。取而代之的是，验证码很好地显示了出来，并且它的进度条有点动画了，然后完成了而没有任何错误，确认我是人类。 此行为是正常现象，没有任何错误。
但是。我想强制验证码显示上面的复选框，它如上所述工作得很好。“复选框”是指 eg “显示行人过路处的复选框，人类用户必须声称通过检查可以识别”。官方文档没有说明如何执行：https://developer.android.com/training/safetynet/recaptcha#send-request
我遵循了以下文档：https://developer.android.com/training/safetynet/recaptcha#send-request。但是，它没有提供有关如何解决我的问题的任何信息。
我没有发现任何相关问题。实际上，除了一个非常简短的问题（它没有提供任何有用的数据来解决我的问题）之外，我还没有找到有关如何为Android实现ReCaptcha的任何问题。
我将向您展示如何实现他们的Android API ReCaptcha（安全网ReCaptcha）以帮助您。
我的应用程序的用户可以注册，登录和注销。
当用户启动我的应用程序时，将显示一个初始屏幕。如果用户未连接，则邀请他触摸按钮。
2.1。如果他触摸该按钮，则ReCaptcha将启动。
2.1.1. If the ReCaptcha is successfully completed, then the user can sign-up and sign-in with his Google account (I use Google Firebase Auth and even AuthUI).
2.1.2. Otherwise, nothing occurs : he'll have to re-try to complete ReCaptcha.
AppCompatActivity类）：“ onClick”事件处理程序，监听按钮上的“ touch”事件在简历中：我将监听器附加到按钮上。因此，如果单击后者，我将在{synchrone！中自愿呼叫verifyWithRecaptcha中调用Executor。然后，我打电话给Google的服务器，以确保验证码是由人而不是机器人完成的，这要归功于我的课程NetworkUseRecaptcha提供了Google服务器的result。

https://developers.google.com/android/reference/com/google/android/gms/safetynet/SafetyNetClient#verifyWithRecaptcha(java.lang.String)：“如果reCAPTCHA确信这是真实设备上的真实用户，它将返回令牌而没有任何挑战。否则，它将提供视觉/听觉挑战，以证明用户的人性返回令牌。”
所以我的愿望不可能具体化...
