自动版本检测更新

主界面登录自动检查更新

checkupdateagent.addListener(checkUpDate);
checkupdateagent.start();

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();
}
