Google Play Game Services unlocks the achievement - keep the unlock in the game or unlock the call () every time?

Question

I am developing an Android game that uses the Google Play Game services.

When a player reaches, for example, 10,000 points, the achievement is unlocked. So when a player reaches 10,000 points, I call

Games.Achievements.unlock(...)

The question is what to do when the user again reaches 10,000 points in another game. Do I have to check if this achievement has already been unlocked or can I call unlock () again?

I know that the “Services” popup only expands when the achievement is first unlocked. But I'm worried about the quota of api calls. If, for example, I keep unlocking achievements from the general settings, I would do something like this:

if(myAchievementIsLocked){
   Games.Achievements.unlock(...)
}
