自定义Androidk全量更新组件
自动更新功能对于一个APP来说是必备的功能，特别是对于未投放市场下载的APP，每次都让用户删掉原来的，再下载新的版本，肯定是不合适的。
实现思路：
- 后台提供接口，返回服务端版本号serviceVersion以及APK下载地址
- 前端对接接口，用拿到的serviceVersion和APK配置的localVersion比较，如果serviceVersion>localVersion则提示可以更新，通过获取的APK下载地址下载，然后通过api打开安装完成更新。
注意：
- localVersion笔者使用的是versionCode,可以再AndroidManifest中配置，通过java代码获取。笔者与后台约定了Code的规则，采用更新时间编辑，例如2018年8月2号，则versionCode=“180802”
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.mintu.dcdb"
android:versionCode="180802"
android:versionName="3.6"> /**
* 获取当前本地apk的版本号
* @param mContext
* @return
*/
public static int getVersionCode(Context mContext) {
int versionCode = 0;
try {
//获取软件版本号，对应AndroidManifest.xml下android:versionCode
versionCode = mContext.getPackageManager().
getPackageInfo(mContext.getPackageName(), 0).versionCode;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return versionCode;
}- 对于Android7.0以上的手机，打开附件做了改变，无法使用以往的uri发布意图，详情可见笔者之前的一篇文章。Android7.0以上版本打开附件失败问题
- 本文的文件下载、附件打开方法使用的是笔者封装的OkHttp3工具类，使用者可以自己随意替换。只要将APK从url上下载下来，用API打开即可。
