GoogleClentientSecrets在调试构建中工作，但未在发行版中进行

Question

我的代码在调试模式下正常工作，但在发行版中不起作用。

GoogleClientSecrets clientSecrets =
                GoogleClientSecrets.load(
                        JacksonFactory.getDefaultInstance(), new InputStreamReader(getAssets().open(Constants.CLIENT_SECRET_FILE)));
        clientSecrets.getWeb().toPrettyString();

我已经检查了JacksonFactory，inputstream和inputstreamreader都不是无效的。并且对象clientSecrets具有带有" Web"标签的JSON。我可以用clientSecrets.toPrettyString();

打印JSON

但是clienterecrets.getweb((正在返回null。" Web"必须无效才能进一步进行，因为它是分解文件中的先决条件。

public final class GoogleClientSecrets extends GenericJson {
...
 public Details getDetails() {
  // that web or installed, but not both
  Preconditions.checkArgument((web == null) != (installed == null));
  return web == null ? installed : web;
 }
...
}

这是我的gradle文件

我缺少发布的版本？

Answer 1

问题是proguard文件。仅保留GoogleClecteCrets的班级名称无效。我必须保留所有变量和方法。

-keep class com.google.api.client.json.jackson2.JacksonFactory { *; }
-keep class sun.nio.cs.StreamDecoder { *; }
-keep class com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets { *; }
-keep class com.google.api.client.json.JsonFactory { *; }
