我正在尝试从json文件加载Google凭据.所以在此之前,我知道,我们必须获得默认的Google传输.参考.但它始终给予null.有人遇到过这个问题吗？

这是我的片段:

try {
        JSON_FACTORY =  JacksonFactory.getDefaultInstance();
        HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();

    } catch (Throwable t) {
        Utilities.writeToLogFile(Constants.LOG_ERROR_LEVEL, ".. EXCEPTION" + t.toString());
    }

这总是以catch部分结束.如下所述

... EXCEPTIONjava.security.KeyStoreException: java.security.NoSuchAlgorithmException: KeyStore JKS implementation not found

我正在开发一个需要与驱动器/电子表格进行交互的android应用程序。我使用的是适用于Android API的Google驱动器，但不仅太费解了，而且无法正常工作。因此，我切换到了REST API。在尝试将其添加到android之前，我以纯Java测试了该应用。完全按预期工作。当将其迁移到android时，我总是很喜欢它

我尝试使用debug.keystore对其进行签名，并且尝试创建自己的密钥库并同时生成两者的签名APK。似乎没有任何作用。

我得出的答案： 附加到Google驱动器文件中，而无需用户选择

如果删除，我也会收到此错误 packagingOptions {exclude 'META-INF/DEPENDENCIES'}

从build.gradle中，我怀疑这可能是找不到JKS的原因？
