public static boolean APKFirstSt(Context context){SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);boolean firstTime = prefs.getBoolean("com.vieworld.function", true);if (firstTime){Editor pEdit = prefs.edit();pEdit.putBoolean("com.vieworld.function", false);pEdit.commit();}return firstTime;}

/** * 获得当前包的版本号 * return **/

public static String ApkVersionCode(Context context){PackageManager pack = context.getPackageManager();PackageInfo packageInfo = null;String versionCode = null;try {packageInfo = pack.getPackageInfo(context.getPackageName(), 0);versionCode = packageInfo.versionName;} catch (NameNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}return versionCode;}

/** * 判断apk是否需要更新 **/

public static boolean IsApkUpdata(String versionCode,String newversionCode){System.out.println(versionCode+"="+newversionCode);if(newversionCode.equals(versionCode )){return true;}elsereturn false;}
