alldemos's Introduction

AllDemos说明

使用Android Studio开发工具,上传的代码包含多个Demo源码,build.gradle文件配置编译版本API 24,配置目标版本API 24,如果Demo需要在Android 6.0以上系统测试,需要添加动态运行权限;如果在Android 7.0系统测试,需要注意行为的变更。

一、目录:

根目录:cn\teachcourse,在该目录下根据Demo的实现效果命名下一级目录,比如:WebView加载H5页面上传表单数据,对应目录view\webview\UploadImgForH5Activity.java

AllDemos目录结构

1.1 onShowFileChooser或openFileChooser,效果图:

源码存放路径:view\webview\UploadImgForH5Activity.java

1.2 你或许理解错了Android系统权限管理的这两个概念,效果图:

源码存放路径:activity\AudioMainActivity.java

1.3 Android开发之深入理解Android 7.0系统权限更改相关文档

  • FileProvider源码路径:nougat/WriteToReadActivity.java
  • DownloadManager源码路径:download/DownloadActivity.java
