我要运行一块code一次性将应用程序安装后。在这之后的特定部分的code不应该得到甚至升级调用。

我怎样才能做到这在Android中？

例如：

 共享preferences preFS = preferenceManager.getDefaultShared preferences（本）;
如果（！prefs.getBoolean（firstTime，FALSE））{
    //运行一次code
    共享preferences.Editor编辑器= prefs.edit（）;
    editor.putBoolean（firstTime，真正的）;
    editor.commit（）;
}
 

I want to run a piece of code once only after the application gets installed. After that that particular piece of code should not get called even for an upgrade.

How can i do this in Android?

For example:

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
if(!prefs.getBoolean("firstTime", false)) {
    // run your one time code
    SharedPreferences.Editor editor = prefs.edit();
    editor.putBoolean("firstTime", true);
    editor.commit();
}
