我在电话认证系统中没有收到firebase的Otp

Question

我基本上创建了2个Xml。一个是用户输入电话号码，然后按下按钮，它会转到OTP验证屏幕。但这里的问题是我没有收到来自Firebase的任何OTP，但5秒后我收到一条敬酒消息，验证失败。如果我甚至没有收到消息，它怎么会失败。我还尝试输入另一个号码，以便我可以手动输入代码。但是Firebase没有向我发送OTP。

基本实现---点击忘记密码-

另外，我已经在Firebase中启用了电话身份验证。

请帮帮我。谢谢！！！

Answer 1

在用户电话号码前添加国家代码（印度为91）。它会起作用的。

NumberEnteredByUser = "91"+intent.getStringExtra("phoneNo");   

Answer 2

验证失败，因为你没有启用应用验证。为此，您可以按照以下步骤操作：

>

转到谷歌云控制台，选择你的项目并启用Android设备验证。以下是直接链接：https://console.cloud.google.com/apis/library/androidcheck.googleapis.com

现在，在app level grade中添加浏览器依赖项，因为应用需要从浏览器打开验证码验证页面：

 implementation 'androidx.browser:browser:1.3.0' 

然后，在Android Studio顶部菜单中构建

现在，你可以走了。

注意：你的应用程序可能会显示验证码验证网页
