Android determines whether the program is running in the foreground or in the background

Just a simple method, no need to write any steps:

public static boolean Frontdesk(Context context) {
 ActivityManager activityManager = (ActivityManager) context
   .getSystemService(Context.ACTIVITY_SERVICE);
 List&lt;&gt; appProcesses = activityManager
   .getRunningAppProcesses();
 for ( appProcess : appProcesses) {
  if ((())) {
   ((), "thisappimportace ="
     + 
     + ",().getName()="
     + ().getName());
   if ( != .IMPORTANCE_FOREGROUND) {
    ((), "In the background"
      + );
    return true;
   } else {
    ((), "In the front desk"
      + );
    return false;
   }
  }
 }
 return false;
}

Just call the Frontdesk(context) method where needed
