Regarding the Service in Android's four major components, please do not select the correct statements from the following [Multiple Choice Question]
1. Service must perform time-consuming operations in the main thread, otherwise it may cause stuttering
2. Among Android's four major components, Service runs in the background and definitely will not block the main thread
3. Service's lifecycle does not depend on the Activity that starts the Service
4. A Service can only be started once; multiple calls to the startService() method have no effect
5. Service can use the stopSelf() method to stop the service
Since 1,2,3,4 are wrong, but the problem asks "do not select the correct statements", you need to choose 1,2,3,4.
