无法将我的Android Studio应用程序与Dropbox连接，但是代码在Eclipse中执行

问题描述 投票：0回答：1

我目前无法通过android studio访问我的保管箱帐户。我打算使用保管箱来存储用户上传到我的应用程序中的照片，然后将保管箱文件名存储在数据库中。我已经在Eclipse上测试了此代码，它的工作原理很吸引人。但我根本无法使其在android studio中正常工作。我以为我在android studio中某处缺少步骤...但是我找不到那一步可能是什么。我将不胜感激。

我已将以下内容添加到我的build.gradle中

implementation 'com.squareup.picasso:picasso:2.71828'
implementation 'com.dropbox.core:dropbox-core-sdk:3.1.1'

我也将此添加到了该软件包下的android清单中。

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

这是我尝试执行的简单代码。请注意，我的ACCESS_TOKEN已存储为最终字符串，并且确实包含正确的访问令牌（如前所述，我可以在eclipse中完美运行此代码（及更多代码））。

public void dropbox(){

        DbxRequestConfig config = DbxRequestConfig.newBuilder("myapp").build();
        DbxClientV2 client = new DbxClientV2(config, ACCESS_TOKEN);  
        FullAccount account = null;
        try {
            account = client.users().getCurrentAccount(); //This is where my error occurs
        } catch (DbxException e) {
            e.printStackTrace();
        }
        Log.d("test",account.getName().getDisplayName());



    }

这是我收到的完整错误消息。

这是因为您正在主线程上运行HTTP请求，这是简单的解决方法：

Thread thread = new Thread() {
    @Override
    public void run() {
        try {
            FullAccount account = client.users().getCurrentAccount(); 
            Log.d("test",account.getName().getDisplayName());
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
};

thread.start();
