Questions tagged [oncreate]

onCreate refers to one of the lifecycle methods for several components on the Android platform.

The onCreate method is a lifecycle method of several Android components like Activities, Fragments, Services etc.

For activities and fragments, this is the first lifecycle method to be called when that component is first created. It can also provide a Bundle containing the component's previously frozen state, if there was one. This method is generally used to setup the component (for example in an Activity this would translate to creating the UI views, binding data to widgets etc).
