自從友盟關(guān)閉了版本更新功能后，安卓的版本更新只能自己來擼了颁独，結(jié)合之前友盟的版本更新，其實實現(xiàn)起來也簡單伪冰，這里簡單說說版本更新實現(xiàn)的思路：
第一步誓酒，通過接口獲取更新信息（版本號、更新內(nèi)容贮聂、apk下載地址靠柑、是否強制更新）
第二步，通過接口拿到的版本號和本地的版本號進行比較吓懈，如果拿到的版本號比本地的版本號大歼冰，那就進行版本升級
第三步，版本升級分為三種情況：
1耻警、非wifi情況下隔嫡，彈出版本更新提示框，用戶點擊“立即升級”按鈕開始下載apk甘穿，下載完成后提示安裝腮恩。
2、wifi情況下扒磁，直接后臺下載apk庆揪，下載完后彈出版本更新提示框，用戶點擊“立即安裝”按鈕開始安裝apk妨托。
3缸榛、強制更新為true的時候，無論是否wifi情況下兰伤，都是應(yīng)該彈出更新提示框内颗，用戶點擊“立即升級”按鈕開始下載升級，提示框不能取消敦腔，點擊“關(guān)閉”按鈕直接退出app均澳。
基本思路就是上面那樣，下面來看看最雞凍人心的環(huán)節(jié)，如何在自己的app加入版本更新功能找前。
BaseAndroid.checkUpdate(MainActivity.this, 2,
"http://f5.market.mi-img.com/download/AppStore/0f4a347f5ce5a7e01315dda1ec35944fa56431d44/luo.footprint.apk",
"更新了XXX\n修復(fù)OOO", false);
看看效果圖
界面有點丑糟袁，自己修改下吧
當然啦，前提是你得依賴了我的base庫：

哈哈躺盛，你也可以直接復(fù)制版本更新的部分過去就行啦项戴，再根據(jù)自己需求修改下，有什么好的建議記得評論槽惫，因為那個功能我也還沒去優(yōu)化的周叮。
那下面進行代碼分析哈：首先是主方法
/**
* 版本更新
*
* @param context
* @param versionCode 版本號
* @param url apk下載地址
* @param updateMessage 更新內(nèi)容
* @param isForced 是否強制更新
*/
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：引導(dǎo)更新界斜，1：安裝更新仿耽，2：強制更新
if (UpdateManager.getInstance().isWifi(context)) {
type = 1;
}
if (isForced) {
type = 2;
}
//檢測是否已下載
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);
//設(shè)置參數(shù)
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的封裝啦，自己看代碼吧各薇，有什么優(yōu)化點評論下项贺，我去修改哈。
