由于项目中要求实现版本升级,特写此代码,有因为这段代码基本都是通用,所以记录下来,以便下次直接拷贝...

以上就是版本检测与下载的 工具类, 直接引入项目即可,可能做法比较简单,勿喷... 里面有一个判断==0,表示不需要强制更新,==1表示需要强制更新,根据客户要求做的,就是这个json字段

Integer.valueOf(versionItem.getUpdatevs())==0

布局如下:

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content">
    
       <ProgressBar
          android:id="@+id/update_progress"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          style="?android:attr/progressBarStyleHorizontal" />
    
    </LinearLayout>
