Android实战之app版本更新升级全文章(二)

来源:互联网 发布:企业信息化软件有哪些 编辑:程序博客网 时间:2024/06/06 03:22

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


界面有点丑,自己修改下吧

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。

/** * 版本更新 */public class UpdateManager {    private String downLoadPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/downloads/";    private int type = 0;//更新方式,0:引导更新,1:安装更新,2:强制更新    private String url = "";//apk下载地址    private String updateMessage = "";//更新内容    private String fileName = null;//文件名    private boolean isDownload = false;//是否下载    private NotificationManager mNotifyManager;

       }        return updateManager;    }    private UpdateManager() {    }    /**     * 弹出版本更新提示框     */    public void showDialog(final Context context) {        String title = "";        String left = "";        boolean cancelable = true;        if (type == 1 | isDownload) {            title = "安装新版本";            left = "立即安装";        } else {            title = "发现新版本";            left = "立即更新";        }        if (type == 2) {            cancelable = false;        }        dialog = new BaseDialog.Builder(context).setTitle(title).setMessage(updateMessage).setCancelable(cancelable)                .setLeftClick(left, new View.OnClickListener() {                    @Override                    public void onClick(View view) {                        dialog.dismiss();                        if (type == 1 | isDownload) {                            installApk(context, new File(downLoadPath, fileName));                        } else {                            if (url != null && !TextUtils.isEmpty(url)) {                                if (type == 2) {                                    createProgress(context);                                } else {                                    createNotification(context);                                }                                downloadFile(context);                            } else {                                Toast.makeText(context, "下载地址错误", Toast.LENGTH_SHORT).show();
