  • Have you considered the privacy implications from the user's perspective? How will you let them know they are being tracked in this fashion? Will you have a privacy policy? – halfer Aug 16 '18 at 10:39

I think this should be helpful: 

@SuppressLint("HardwareIds")
String android_id = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);

  • If you mention hardware identifiers as a method of tracking users, you really should mention the privacy implications. Users often do not like to be tracked in this way, and at the very least their permission should be sought. – halfer Aug 16 '18 at 10:38
