Android 版本更新

摘要

版本更新这一块涉及的知识点比较少，但也花了一天时间，仅做记录用，为了方便大家理解，我画了一张流程图。需求比较简单，以后可以根据产品需求适当更改。

以下版本更新工具类

* on 2019/1/23 * 检查更新版本工具类 downLoadPath url isforce oldApkName newApkName context updataDialog installDialog progressDialog fm updateManager updateManager updateManager updateManager * 版本更新提示框 updataDialog v updataDialog isforce v updataDialog context updataDialogfm * 弹出安装Dialog content installDialog content v installDialog isforce v installDialog fileAPK downLoadPath newApkName context fileAPK installDialogfm * 检查有没有最新的APK file downLoadPath file file fileAPK downLoadPath newApkName fileAPK * 删除旧的apk fileAPK downLoadPath oldApkName fileAPK fileAPK * 下载APK startTime startTime myURL url conn myURL conn is conn fileSize conn fileSize fileSize is file1 downLoadPath file1 file1 fos downLoadPath newApkName buf downLoadFileSize numread isbuf numread fosbuf numread downLoadFileSize numread downLoadFileSize fileSize downLoadFileSizefileSize progressDialogdownLoadFileSizefileSize progressDialog startTime is ex ex ex * 强制更新时显示在屏幕的进度条 context progressDialog context progressDialog progressDialog progressDialog progressDialogSTYLE_HORIZONTAL progressDialog * 安装apk context file intent ACTION_VIEW VERSIONSDK_INT contentUri context file intentFLAG_ACTIVITY_NEW_TASK intentFLAG_GRANT_READ_URI_PERMISSION intentcontentUri intentFLAG_ACTIVITY_NEW_TASK intentfile contextintent * apk网络地址 context context context * apk网络地址 url url url * 新版本文件名 fileName newApkName fileName * 旧版本文件名 fileName oldApkName fileName * Fragment管理器 fm fm fm * 下载路径 downLoadPath downLoadPath downLoadPath * 是否强制更新 isforce isforce isforce

下面是发起调用

context fm versionCode url isForced versionCode context downLoadPath context newFileName versionCode oldFileName context context fm downLoadPath newFileName oldFileName url isForced

其中安装apk需要注意下,在manifest文件中加入代码

provider androidname androidauthorities androidgrantUriPermissions androidexported metadata androidname androidresource provider
