Activity.OnStart Method

Definition

Called after #onCreate — or after #onRestart when the activity had been stopped, but is now again being displayed to the user.

Attributes

Remarks

Called after #onCreate &mdash; or after #onRestart when the activity had been stopped, but is now again being displayed to the user. It will usually be followed by #onResume. This is a good place to begin drawing visual elements, running animations, etc.

You can call #finish from within this function, in which case #onStop will be immediately called after #onStart without the lifecycle transitions in-between (#onResume, #onPause, etc) executing.

<em>Derived classes must call through to the super class's implementation of this method. If they do not, an exception will be thrown.</em>
