我想使用Google Drive API for Android列出用户云端硬盘的Root文件夹中的所有文件.

我尝试过的:

1. 使用SCOPE_FILE和listChildren:

   mGoogleApiClient = new GoogleApiClient.Builder(this)
           .addApi(Drive.API)
           .addScope(Drive.SCOPE_FILE)
           .addConnectionCallbacks(this)
           .addOnConnectionFailedListener(this)
           .build();

然后列出文件:

Drive.DriveApi.getRootFolder(mGoogleApiClient)
    .listChildren(mGoogleApiClient)
    .setResultCallback(new ResultCallback<DriveApi.MetadataBufferResult>() {
        @Override
        public void onResult(DriveApi.MetadataBufferResult result) {
            if (!result.getStatus().isSuccess()) {
                Log.v("DKDK", "Request failed");
                return;
            }
            MetadataBuffer metadataBuffer = result.getMetadataBuffer(); // empty!
        }
    }

我发现是SCOPE_FILE只列出由应用程序,并不是所有的文件被创建的文件.

2. 使用https://www.googleapis.com/auth/drive范围

   mGoogleApiClient = new GoogleApiClient.Builder(this)
           .addApi(Drive.API)
           .addScope(new Scope("https://www.googleapis.com/auth/drive"))
           .addConnectionCallbacks(this)
           .addOnConnectionFailedListener(this)
           .build();

失败,例外:
