自从友盟关闭了版本更新功能后，安卓的版本更新只能自己来撸了，结合之前友盟的版本更新，其实实现起来也简单，这里简单说说版本更新实现的思路：
第一步，通过接口获取更新信息（版本号、更新内容、apk下载地址、是否强制更新）
第二步，通过接口拿到的版本号和本地的版本号进行比较，如果拿到的版本号比本地的版本号大，那就进行版本升级
第三步，版本升级分为三种情况：
1、非wifi情况下，弹出版本更新提示框，用户点击“立即升级”按钮开始下载apk，下载完成后提示安装。
2、wifi情况下，直接后台下载apk，下载完后弹出版本更新提示框，用户点击“立即安装”按钮开始安装apk。
3、强制更新为true的时候，无论是否wifi情况下，都是应该弹出更新提示框，用户点击“立即升级”按钮开始下载升级，提示框不能取消，点击“关闭”按钮直接退出app。
基本思路就是上面那样，下面来看看最鸡冻人心的环节，如何在自己的app加入版本更新功能。
BaseAndroid.checkUpdate(MainActivity.this, 2,
"更新了XXX\n修复OOO", false);
看看效果图
界面有点丑，自己修改下吧那下面进行代码分析哈：首先是主方法
/**
* 版本更新
*
* @param context
* @param versionCode 版本号
* @param url apk下载地址
* @param updateMessage 更新内容
* @param isForced 是否强制更新
*/
public static void checkUpdate(Context context, int versionCode, String url, String updateMessage, boolean isForced) {
if (versionCode > UpdateManager.getInstance().getVersionCode(context)) {
int type = 0;//更新方式，0：引导更新，1：安装更新，2：强制更新
if (UpdateManager.getInstance().isWifi(context)) {
type = 1;
}
if (isForced) {
type = 2;
}
//检测是否已下载
String downLoadPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/downloads/";
File dir = new File(downLoadPath);
if (!dir.exists()) {
dir.mkdir();
}
String fileName = url.substring(url.lastIndexOf("/") + 1, url.length());
if (fileName == null && TextUtils.isEmpty(fileName) && !fileName.contains(".apk")) {
fileName = context.getPackageName() + ".apk";
}
File file = new File(downLoadPath + fileName);
//设置参数
UpdateManager.getInstance().setType(type).setUrl(url).setUpdateMessage(updateMessage).setFileName(fileName).setIsDownload(file.exists());
if (type == 1 && !file.exists()) {
UpdateManager.getInstance().downloadFile(context);
} else {
UpdateManager.getInstance().showDialog(context);
}
}
}
然后就是UpdateManager的封装啦，自己看代码吧，有什么优化点评论下，我去修改哈。

private String downLoadPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/downloads/";
