Question

您好我是Android Studio新手，我正在处理我的webView中的DownloadListener，以便下载已经上传到网页上的文件，基本上你可以说一个pdf格式的文件，不过我试过了我的水平最好找到错误，但找不到错误。错误在于我们点击网页上的一些可下载链接它显示的错误就是这样：

---
# this manifest deploys two applications
# apps are in flame and spark directories
# flame and spark are in fireplace
# cf push should be run from fireplace
applications:
- name: spark
  memory: 1G
  instances: 2
  host: flint-99
  domain: shared-domain.com
  path: ./spark/
  services:
  - mysql-flint-99
- name: flame
  memory: 1G
  instances: 2
  host: burnin-77
  domain: shared-domain.com
  path: ./flame/
  services:
  - redis-burnin-77

我的活动代码如下：
