Agent版本获取服务端版本信息

public class CheckUpdateAgent extends AbstractAgent<String> {    public static final String KEY_VERSION = "version";    public static final String KEY_URL = "url";    public static String desc;    private int sleepMiSec = 4000;    public CheckUpdateAgent(){        this(3000);    }    public CheckUpdateAgent(int sleepMiSec){        this.sleepMiSec = sleepMiSec;    }    @Override    protected String doExecute() throws HttpRPCException {        try {            new TimeFairy(sleepMiSec).sleepIfNecessary();            URL updateURL = new URL(AppUtil.getUpdateURL());            HttpURLConnection conn = (HttpURLConnection) updateURL.openConnection();            Properties props = new Properties();            props.load(conn.getInputStream());            String version = props.getProperty(KEY_VERSION);            String  url=null;            if(AppUtil.shouldUpdateToNewVersion(version)){                url = props.getProperty(KEY_URL);                desc=props.getProperty("desc");            }            return url;        } catch (Exception ex) {            throw new HttpRPCException(ex.getMessage(), 0, ex);        }    }}

工具APPUtil，版本判断，

 public static boolean shouldUpdateToNewVersion(String serverVersion) {        String[] curVersions = versionName.split("[.]");        String[] serverVersions = serverVersion.split("[.]");        for (int i = 0; i < 3; i++) {            int curVersion = Integer.parseInt(curVersions[i]);            int servVersion = Integer.parseInt(serverVersions[i]);            if (curVersion > servVersion) {                return false;            } else if (curVersion < servVersion) {                return true;            }        }        return false;    }

监听返回

 /**     * 获取更新数据监听     */    private AgentListener<String> checkUpDate = new AgentListener<String>() {        @Override        public void onStarted(long seq) {        }        @Override        public void onSucceeded(String info, long seq) {            if(info!=null) {                updateManager = new UpdateManager(MainAct.this, info);                showUpDate();            }        }        @Override        public void onFailed(String errMsg, int errCode, long seq) {            ViewUtil.showToast("更新失败，请重使");        }    };

弹窗更新与否

  /**     * 更新提示框     */    private void showUpDate() {        AlertDialog.Builder builder = new AlertDialog.Builder(MainAct.this);        builder.setMessage("检测到新版本，确认安装吗？");        builder.setTitle("更新信息");        builder.setPositiveButton("立刻安装", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                dialog.dismiss();                updateManager.checkUpdateInfo();            }        });        builder.setNegativeButton("稍后再说", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                dialog.dismiss();            }        });        builder.show();    }
