Android: Go back to previous activity

I want to do something simple on android app.
How is it possible to go back to a previous activity.

What code do I need to go back to previous activity

Answer

Android activities are stored in the activity stack. Going back to a previous activity could mean two things.

  1. You opened the new activity from another activity with startActivityForResult. In that case you can just call the finishActivity() function from your code and it'll take you back to the previous activity.

  2. Keep track of the activity stack. Whenever you start a new activity with an intent you can specify an intent flag like FLAG_ACTIVITY_REORDER_TO_FRONT or FLAG_ACTIVITY_PREVIOUS_IS_TOP. You can use this to shuffle between the activities in your application. Haven't used them much though. Have a look at the flags here: http://developer.android.com/reference/android/content/Intent.html
