我正在构建一个Android应用，并且已经实现了google＆facebook auth。 （API级别：19）
问题是：这些身份验证方法在我的模拟电话上可以正常使用，但在实际情况下（例如，真实电话，例如个人电话）却无法使用。
我设法添加了一些带有详细信息的Log.i（），我发现Google登录按钮返回了： com.google.android.gms.common.api.apiException：10 （是的，我知道，stackoverflow上存在有关此错误代码的问题），但我没有使用firebase，只是使用了Google开发人员控制台（console.developers.google.com）。
因此，我将重现对两种auth方法执行的步骤：
Google身份验证：
1）我去了：console.developers.google.com/apis
2）然后单击“创建凭据”按钮
3）选择OAuth客户端ID选项
4）选择Android选项
5）从我的android应用程序中添加了程序包名称（就像：com.xyz.xyz）
6）作为签名证书指纹，我使用了SHA-1 android studio生成的代码（单击右侧按钮“ Gradle”，然后从项目目录中选择“ app”->“ Tasks” ->“ android”->“ signingReport”，复制SHA1生成的代码并使用它。）
7）创建然后在列表中添加的新服务/应用程序（无论它是什么），我复制了其客户端ID并将其粘贴到app / res / values / strings.xml中，如下所示：
<string name="server_client_id">random_numbers-random_numbers_and_letters.apps.googleusercontent.com</string>
Facebook身份验证
1）我去了：developers.facebook.com/apps，那里已经有一些应用程序，所以我只配置了其中一个来支持这个android应用程序
2）我单击设置->基本->添加平台（在页面底部）-> Android
3）然后，我几乎遵循了他们教程中的内容。
在这里我还会有一些问题： 对于我使用的Facebook身份验证，请在app / res / values / strings.xml内
<string name="facebook_app_id">some_generated_numbers</string>
<string name="fb_login_protocol_scheme">fbsome_other_generated_numbers</string>
问题1：fb_login_protocol_scheme字符串值是什么？
问题2：如果没有该应用程序，该应用程序仍然可以运行吗？
问题3：如果我丢失了它，在哪里/如何再次找到它？
这是活动中的xml（facebook和google按钮）：
<FrameLayout android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity">
<com.google.android.gms.common.SignInButton android:id="@+id/googleLogin" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="onClick" android:layout_gravity="center_horizontal" android:layout_marginTop="50dp" />
<com.facebook.login.widget.LoginButton android:id="@+id/facebookLogin" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="onClick" android:layout_gravity="center_horizontal" android:layout_marginTop="10dp" />
</FrameLayout>
