为什么不推荐“使用 getString()来获取设备标识符”？

我试图把我的设备 ID 带到 Logcat，但是安卓工作室给了我这个警告。

不推荐使用 getstring 获取设备标识符

String deviceID = Settings.Secure.getString(getApplicationContext().getContentResolver(),
Settings.Secure.ANDROID_ID);

为什么不推荐呢？

The full warning says:

Using these device identifiers is not recommended other than for high value fraud prevention and advanced telephony use-cases. For advertising use-cases, use AdvertisingIdClient$Info#getId and for analytics, use InstanceId#getId.

I think Android does not recommend using this value, since it's a permanent unique id, which can be used to track your user, and he or she can't change this id or prevent you to read it. The other options given in the warning respects your user's wishes. That's why Android recommend you to use that.

It really depends on what you are going to do with that id. Privacy is a sensitive thing these days.

Also check this:

...you must abide by a user’s ‘Opt out of interest-based advertising’ or 'Opt out of Ads Personalization' setting. If a user has enabled this setting, you may not use the advertising identifier for creating user profiles for advertising purposes or for targeting users with personalized advertising. Allowed activities include contextual advertising, frequency capping, conversion tracking, reporting and security and fraud detection.
