Android在使用谷歌日历API时为IOException提供``无法创建目录:/令牌'' [英] Android giving IOException with 'unable to create directory: /tokens' when using google calendar api

问题描述

尝试在Android中实现Calendar Quickstart API，但是当我如所示声明令牌时. private final String TOKENS_DIRECTORY_PATH = "tokens";

Trying to implement the Calendar Quickstart API into Android but when I declare tokens as demonstrated. private final String TOKENS_DIRECTORY_PATH = "tokens";

然后在构建器中使用该字符串

That String is then used in the builder

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setAccessType("offline")
                .build();

但是，当设置DataStoreFactory

java.io.IOException: unable to create directory: /tokens

是否有其他方法可以创建可以使用的目录?还是必须更改TOKENS_DIRECTORY_PATH的文件路径?

Is there a different method to creating a directory that will work? or must I change the file path of TOKENS_DIRECTORY_PATH?

推荐答案

我使用了这段代码.

File tokenFolder = new File(Environment.getExternalStorageDirectory() +
            File.separator + TOKENS_DIRECTORY_PATH);
    if (!tokenFolder.exists()) {
        tokenFolder.mkdirs();
    }

    flow = new GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
            .setDataStoreFactory(new FileDataStoreFactory(tokenFolder))
            .setAccessType("offline")
            .build();

并获得Android清单文件中外部存储的权限

And get permissions to external storage in Android manifest file

编辑:在Google API文档中为Java指定的方法似乎不适用于Android.将此 github项目用作将Google API集成到Android应用程序中的指南.

The methods specified in Google API documentation for Java doesn't seem to work well for Android. Use this github project as a guide for implementing integrating Google APIs into Android applications.
