文章标签 java自动升级后程序无法使用 java程序远程自动更新 ide java 服务器 文章分类 Java 后端开发

1、之前写过一篇说版本升级的，用到广播。感觉乱用，搞的有点复杂，且混乱。现在又用到了版本升级功能，然后梳理下思路，使用回调接口重新写了个。

3、增加了点小功能：

1>、可以手动检查升级；

2>、显示升级日志；

3>、修改上篇博客潜在问题：

问题：后台查询到更新，提示更新的AlertDialog只能在启动更新的页面弹出；如果离开此页面，抛异常。

解决：在app的所有页面顶层弹出，参考代码：

//设置dialog
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
//加入权限

4、截图如下：

5、上代码(代码才能说明一切)：

String UPDATE_DATE = "updatedate";
String APK_VERSION = "apkversion";
String APK_VERCODE = "apkvercode";
String CHECK_DATE = "checkdate";
}
}

代码内容我不讲解，使用的是回调接口。

(5)、其他操作类：

a、Const.java是一个常量存储类，保存检查更新地址等；

b、Escape.java是个URL解码编码类；

c、HttpRequestUtil.java获取远程数据类；

d、IntentUtil.java工具类，如：检查网络连接状态等。

(以上类参考附件源码)/**

* apk更新信息
* @author： aokunsang
* @date： 2012-12-18
*/
public class ApkInfo implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private String downloadUrl; //下载地址
private String apkVersion; //apk版本
private String apkSize; //apk文件大小
private int apkCode; //apk版本号(更新必备)
private String apkName; //apk名字
private String apkLog; //apk更新日志
setter and getter...
}

(6)、服务器代码(这里的apklog可以是个txt文档，在UI上下载展示，我做的比较简单)：

/**
* 获取apk更新信息
* {apkVersion:'1.10',apkSize:'36K',apkVerCode:2,apkName:'1.1.apk',apkDownloadUrl:'http://localhost:8080/myapp/1.1.apk',apklog:'1、修改页面;\n2、修改字体'}
*/
@Action(value="checkUpdateApk")
public String updateApk(){
ResourceLoader loader = new DefaultResourceLoader();
Properties pp = null;
try {
InputStream is = loader.getResource("classpath:config/sysconf.properties").getInputStream();
pp = new Properties();
pp.load(new InputStreamReader(is, "utf-8"));
} catch (Exception e) {
e.printStackTrace();
}
if(pp!=null){
String apkVersion = pp.getProperty("apkVersion");
String apkDownloadUrl = pp.getProperty("apkDownloadUrl");
String apkName = pp.getProperty("apkName");
int apkVerCode = NumberUtils.toInt(pp.getProperty("apkVerCode"),0);
String apklog = pp.getProperty("apkLog");
String apkSize = pp.getProperty("apkSize");
Httptear.ResponseResultByEscape("{apkVersion:'"+apkVersion+"',apkSize:'"+apkSize+"',apkVerCode:"+apkVerCode+",apkName:'"+apkName+"',apkDownloadUrl:'"+apkDownloadUrl+"',apklog:'"+apklog+"'}");
}else{
Httptear.ResponseResultByEscape("{}");
}
return NONE;
}

6、

upgrade_apk.xml<?xml version="1.0" encoding="utf-8"?>
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
android:id="@+id/progressCount_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@color/white"
android:textSize="14dip"
/>
android:id="@+id/progressbar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

7、需要加入以下权限：

8、启动更新检查代码：

/* 升级程序[主动] (因为会弹出一个ProgressDialog窗口，不能使用getApplicationContext())*/
DownloadManager downManger = new DownloadManager(this,true);
downManger.checkDownload();/* 升级程序启动[被动](使用this引用会导致：如在1页面启动升级，当前页面为2页面，此时弹出Dialog抛异常)*/
DownloadManager downManger = new DownloadManager(getApplicationContext(),false);
downManger.checkDownload();
