Android实战之app版本更新升级全文章(二)
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,
-
"http://f5.market.mi-img.com/download/AppStore/0f4a347f5ce5a7e01315dda1ec35944fa56431d44/luo.footprint.apk",
-
"更新了XXX\n修复OOO", false);
看看效果图
当然啦,前提是你得依赖了我的base库:

哈哈,你也可以直接复制版本更新的部分过去就行啦,再根据自己需求修改下,有什么好的建议记得评论,因为那个功能我也还没去优化的。
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。
