android检查更新、下载、安装

前言:

由于友盟更新即将下线,我们就修改了更新逻辑,自己检查更新、下载、安装,但是检查更新还是要依赖于友盟中的在线参数:

1.mainactivity.java:

public class mainactivity extends baseactivity{
 @override
 public void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_main);
  checkupdateutil.checkupdate(this);//检查更新
 }
}

2.checkupdateutil.java:
