Android 联系人 API - Android 5.1+ 中的查找键是否仍会发生变化？
Android Contacts API - Does Lookup Key still change in Android 5.1+?
This question from 2010 asks if you can manage contacts using the Lookup Key. According to the Official Android Developer Documentation，查找密钥对联系人来说是永久性的 link。但是，问题的答案是 查找键可能会改变。
那是 Android 2.x 天...
Does this fact still remain true? Does the Lookup Key still change or
can I reliably use it as a link to a contact regardless of aggregation
and sync operations now? (My minSdkVersion is 22 - Android 5.1 Lollipop and above)
我问是因为我想将查找键存储在数据库中，并在下次 运行 通过联系人列表时排除那些特定的联系人。
是的，查找键仍然会改变。您最好保存自定义值并在下次查看该特定值是否存在。
