Android determines whether the app is running on the foreground

In Android development, it is sometimes necessary to determine whether the app is running on the foreground.

CodeThe implementation is as follows:

 private Boolean isrunningforeground (context) {activitymanager AM = (activitymanager) context. getsystemservice (context. activity_service); componentname Cn = aM. getrunningtasks (1 ). get (0 ). topactivity; string currentpackagename = cn. getpackagename (); If (! Textutils. isempty (currentpackagename) & currentpackagename. Equals (getpackagename () {return true ;}return false ;}

Note:Androidmanifest. xml needs to be added< Uses-Permission Android: Name ="Android. Permission. get_tasks" />
