无法将我的 android studio 应用程序与 dropbox 连接，但代码在 Eclipse 中执行

Question

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 上测试了这段代码，它运行起来非常棒。但我根本无法让它在 android 工作室中工作。我假设我在 android 工作室的某处遗漏了一个步骤......但我找不到那个步骤可能是什么。如果有任何帮助，我将不胜感激。

我已将以下内容添加到我的 build.gradle

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

我也已将此添加到我的 android 包下的清单中。

<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，我将 ACCESS_TOKEN 存储为最终字符串，它确实包含正确的访问令牌（正如我之前提到的，我可以运行在 eclipse 中完美地使用此代码（以及更多）。

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。

发生这种情况是因为您是运行主线程上的 HTTP 请求，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();
