how to prevent service to run again if already running android
android, android-service, service
Solution
A service will only run once, so you can call `startService(Intent)` multiple times.
You will receive an `onStartCommand()` in the service. So keep that in mind.
Source: Note that multiple calls to `Context.startService()` do not nest (though they do result in multiple corresponding calls to `onStartCommand()`), so no matter how many times it is started a service will be stopped once `Context.stopService()` or `stopSelf()` is called; however, services can use their `stopSelf(int)` method to ensure the service is not stopped until started intents have been processed.

Problem
On click of a button I want to start service using method `startService(new Intent(currentActivity.this,MyService.class))` but if service is running I don't want to call this method to avoid run service that is already running.How this is possible.I am using both Intent service and Service in same project and want to apply same condition for both.
