Hi, Friends in this below article I am going to discuss about android tips and tricks for our android application development. In this android tips and tricks are very use full in android app development.

 

Normally when we launch a new activity, it’s previous activities will be kept in a queue like a stack of activities. So if you want to kill all the previous activities, just follow these methods.

Method 1

In API level 11 or greater, use FLAG_ACTIVITY_CLEAR_TASK and FLAG_ACTIVITY_NEW_TASK flag on Intent to clear all the activity stack.

Intent i = new Intent(OldActivity.this, NewActivity.class);
// set the new task and clear flags
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK)
startActivity(i);
