Is there on install event in android?
提问by Dmytro
Is there some event/receiver or something for handling first execution after installation or directly after installation? Or Do I need it emulate with preferences?
是否有一些事件/接收器或用于在安装后或直接在安装后处理第一次执行的东西？或者我需要它模拟偏好吗？

There is the ACTION_PACKAGE_ADDEDBroadcast Intent, but the application being installed doesn't receive this.
有ACTION_PACKAGE_ADDED广播意图，但正在安装的应用程序没有收到这个。
So checking if a preference is set is probably the easiest solution.
因此，检查是否设置了首选项可能是最简单的解决方案。
SharedPreferences p = PreferenceManager.getDefaultSharedPreferences(this);
boolean firstRun = p.getBoolean(PREFERENCE_FIRST_RUN, true);
p.edit().putBoolean(PREFERENCE_FIRST_RUN, false).commit();

I don't think there is such a thing, and I don't think this would be a good idea : usually you have to handle not only installations but some updates (say : a new version with features) or the proper initialization of some resources.
我不认为有这样的事情，而且我认为这不是一个好主意：通常，您不仅要处理安装，还要处理一些更新（例如：具有功能的新版本）或正确初始化某些资源。
For the resources, the best way is to check them directly.
对于资源，最好的方法是直接查看它们。
For the version, I use the database, it's so easy.
对于版本，我用的是数据库，就这么简单。

The SQLiteOpenHelper's OnUpgrade method is called when the database version changed. I suppose this could be used to do other things than just handling the new schema.
SQLiteOpenHelper 的 OnUpgrade 方法在数据库版本更改时被调用。我想这可以用来做其他事情，而不仅仅是处理新模式。

See Get referrer after installing app from Android Market- you can put whatever you want in there. I believe this is how Plan Bworks - the app that can send back your phone's location after it's stolen, that you install from the website afterit's been stolen.
请参阅从 Android Market 安装应用程序后获取引荐来源- 您可以在其中放入任何您想要的内容。我相信这就是Plan B 的工作方式 - 可以在手机被盗后发回手机位置的应用程序，您可以在手机被盗后从网站安装该应用程序。
