调用

OssManager.Builder builder=new OssManager.Builder(MainActivity.this);
builder.accessKeyId("——————") ;//秘钥
builder.bucketName("位置");//存储位置http://这里的.oss-cn-shanghai.aliyuncs.com/applog/test.txt
builder.accessKeySecret("——————");//秘钥
builder.endPoint("http://oss-cn-shanghai.aliyuncs.com");//地域节点
builder.objectKey("applog/test.txt");//上传到某个文件夹内部文件
builder.localFilePath(mPicturePath);//上传本地文件路径
builder.build();
