Answer 1

我通过复制相同的密钥哈希来解决这个问题，然后我将其添加到Facebook。我之前也已经这样做了，但当时它没有用。

Answer 2

如果使用Linux操作系统，则需要在命令行工具上使用以下命令创建keyhash。

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

对于Windows：

keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%.android\debug.keystore | openssl sha1 -binary | openssl base64

它会询问您的密码，所以只需输入＆＃34; android＆＃34;它将返回debug.keystore的keyhash。然后将其复制并粘贴到您的Facebook开发者控制台上。当您要发布应用程序时，意味着当您将应用程序的构建创建为已签名的应用程序时，那时只需使用您的应用程序的密钥库并使用相同的命令，但只需将debug.keystore替换为您的密钥库名称，别名和密码。最重要的是，Facebook允许多个键盘，因此当您输入实时键盘时不要删除调试键盘。让他们两个都在那里。
