我正在研究谷歌驱动器并尝试在我的 app.lots 中融入我所做的很多事情。首先我创建 SH1 密钥，然后启用驱动器 api，然后生成 APP 密钥。现在我已经实现了这个链接，但是当我从图库中选择图像时，它重定向回这个活动，我打印图像的路径，它给出了正确的路径和不上传。我现在做什么？请任何人帮助我，我在这里击中了我现在无法理解的内容。

我也使用几乎相同的代码来上传 pdf 文件，但它对我有用，

 try
      {
         FileContent mediaContent = new FileContent("application/pdf",pdfFile);
        com.google.api.services.drive.model.File body = new com.google.api.services.drive.model.File();
        body.setTitle(filename);
        body.setMimeType("application/pdf");
        com.google.api.services.drive.model.File file =     servicer.files().insert(body,mediaContent).execute();
                     if (file != null)
                     {
                         runOnUiThread(new Runnable() {
                             @Override
                             public void run() {
                                 Toast toast = Toast.makeText(getApplicationContext(), "File exported successfully", 2000);
                                 toast.setGravity(Gravity.TOP|Gravity.CENTER, 0, 30);
                                 toast.show();
                             }
                         }
                         );

                     }

                 }
                 catch (UserRecoverableAuthIOException e)
                 {
                     startActivityForResult(e.getIntent(),REQUEST_AUTHORIZATION);
                 }
                 catch (IOException e)
                 {
                     e.printStackTrace();
                 }
