0); code =
info.versionCode; }
catch
(PackageManager.NameNotFoundException
e) {
e.printStackTrace();
} return code; }
2.获取自己应用内部的版本名
public static String
getVersionName(Context
context) { PackageManager manager

try { PackageInfo info =
manager.getPackageInfo(context.getPackageName(),
0); name =
info.versionName; }
catch
