我正在创建一个Android应用，我希望通过使用应用内结算库销售一些视频。我添加了应用内结算并且它正在运行，但如果我购买视频并退回或退出应用程序，视频将再次付费意味着我需要再次购买。所以我想，如果一个用户购买视频，他可以永久地观看它。我从Android Developer＆＃34; https://developer.android.com/training/data-storage/shared-preferences.html#java＆＃34;但它不起作用。请根据我的准则提供帮助。这是我的代码。谢谢。 共享首选项代码根据我的知识和帮助是：
SharedPreferences sp = getPreferences(MODE_PRIVATE);
if (hasUserBought){ // The user bought your video, so save the value now
sp.edit().putBoolean("key_here", true).apply();
}
的onCreate（）
boolean videoBought = sp.getBoolean"key_here", false);
if (videoBought){
... //user bought the video already
}
else {
... //user hasn't bought it yet
}
但是关键在哪里。
