Android 阿里云OSS文件上传的实现示例

估计有小伙伴看到阿里云oss的api文档十脸懵逼了，啊哈哈哈，接下来博主就来拯救你了，看完觉得好的就关注博主吧，么么么么么哒！！！

想要自己研究阿里云oss的，博主开启传送门给你：阿里云oss

一、项目导入阿里云oss的SDK

方式1：在build文件添加依赖（博主和官方一致推荐）

dependencies { //阿里云oss implementation ’com.aliyun.dpa:oss-android-sdk:+’}

方式2：源码编译jar包 源码传送门：官方阿里云oss源码

二、OSS所需要的Android权限

<uses-permission android:name='android.permission.INTERNET' /><uses-permission android:name='android.permission.ACCESS_NETWORK_STATE' /><uses-permission android:name='android.permission.ACCESS_WIFI_STATE' /><uses-permission android:name='android.permission.WRITE_EXTERNAL_STORAGE' /><uses-permission android:name='android.permission.MOUNT_UNMOUNT_FILESYSTEMS' />

三、在项目的proguard-rules.pro文件加入混淆配置

-keep class com.alibaba.sdk.android.oss.** { *; }-dontwarn okio.**-dontwarn org.apache.commons.codec.binary.**

四、重点来了，上代码（只有上传和删除文件的，需要其他的功能就需要自己去研究了）
