Android Spotify SDK 登录错误意外令牌

Question

我正在尝试在 android 应用程序上实施 Spotify SDK，当我单击按钮时，Spotify activity 启动正常，但是当我尝试登录时没有任何反应，它记录了我一个Unexpected token error，我使用了与 Spotify 教程中完全相同的代码，希望你能帮忙

你得到的实际上是 JSON.parse()

处的 JSON 错误

Throws a SyntaxError exception if the string to parse is not valid JSON.

查看您的代码后，我发现您没有完全遵循tutorial.There的规定

The completed code of MainActivity.java should now look like this, but with your own client ID and redirect URI:

因为你的redirect URI没有设置

private static final String REDIRECT_URI = "yourcustomprotocol://callback";

无法解析您的 URI。这与您的错误并非巧合，因为登录过程中使用了重定向 URI，并且基本上是 客户在成功帐户授权后将发送到的位置 .

关于如何设置它，我帮不了你太多，因为我没有使用过 Spotify SDK，但你可以使用类似

private static final String REDIRECT_URI = "http://localhost:PORT_NUMBER://authenticationResponse"

PORT_NUMBER 可以是任何大于 1024

的值

有关更多信息，这个问题可能会有帮助：Spotify redirect URI。

希望你能解决这个问题。
