Activities are run in order of the android lifecycle so oncreate is not called first;it is just the first opportunity you have to call setcontentview to inflate your layout from question Does Android start on AndroidManifest.xml or on the onCreate ()method? |

If you use startactivity in the new activity s oncreate you will also set the contentview;so with respect to time setcontentview alone is faster since it doesn t start a new activity from question SetContentView(R.Layout.main) vs startActivity(intent), which is more common? |
