我要救一个标志认识到我的应用程序运行在第一次与否。对于这个简单的工作，我不想创建数据库。

I want to save a flag for recognizing that my app is run for the first time or not. For this simple job I don't want to create database..

有一个简单的选择要做到这一点？我要保存和读取的小条信息只。

Is there a simple option to do this? I want to save and read little pieces of information only.

推荐答案

使用共享preferences 。

SharedPreferences preferences = getSharedPreferences("prefName", MODE_PRIVATE);
SharedPreferences.Editor edit= preferences.edit();

edit.putBoolean("isFirstRun", false);
edit.commit();
