OnCreate is only called once.
You might want to read through the documentation on the Activity lifecycle. OnCreate will only be called one time for each lifetime of the Activity. However, there are a number of situations that can cause your activity to be killed and brought back to life. Thus, onCreate will be called again.
onCreate(Bundle savedInstanceState) Function in Android: When an Activity first call or launched then onCreate(Bundle savedInstanceState) method is responsible to create the activity.
onCreate(Bundle) is called when the activity first starts up. You can use it to perform one-time initialization such as creating the user interface. onCreate() takes one parameter that is either null or some state information previously saved by the onSaveInstanceState .

To support this properly, you can save state information in onSaveInstanceState and restore it fron the state bundle you get in on create.
