无法使用图库意图从GoogleStorageRi（Google Drive image uri）将图像加载到imageview中

Question

 if ("com.google.android.apps.docs.storage".equals(uri
                    .getAuthority())) {

    //content://com.google.android.apps.docs.storage/document/acc%3D2%3Bdoc%3Dencoded%3DWe%2BdXDcNbYeulVk1Ntu3YfRYkm9wk7uTdTG6LE6yck1BxY4g7xAxyPAgtMtz4A%3D%3D

 final String docId = DocumentsContract.getDocumentId(uri);
                    final String id = docId.split(";")[1];
                    final String[] selectionArgs = new String[]{id};
                    //String[] column = {MediaStore.Images.Media.DATA};


                    // where id is equal to
                    String selection = MediaStore.Images.Media._ID + "=?";
                    Uri contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

                    //..
                    Cursor cursor = null;
                    String filePath = null;
                    try {
                        String[] column = {MediaStore.Images.Media.DATA};

                        cursor = context.getContentResolver().query(contentUri,
                                column, selection, selectionArgs, null);
                        if (cursor != null && cursor.moveToFirst()) {
                            int columnIndex = cursor.getColumnIndex(column[0]);
                            filePath = cursor.getString(columnIndex);
                        }
                    } finally {
                        if (cursor != null)
                            cursor.close();

                        return filePath;


 }
            }

但我得到了空光标。因此，filepath始终为空/null。

任何人，能建议我做错了什么吗？

我使用这段代码从url获取真实路径

删掉吧。
