For most of the android apps we do have multiple activities and when we start another activity either we get no animation (in older devices) or a left-right translation. It is not so cool for a stylish app. We can override these animation in two ways. Here is simplest way using method “overridePendingTransition”
see the example code for switching between Activity1 and Activity2
Intent i = new Intent(Activity1.this,Activity2.class);
This method can be used after calling finish() also.You will have to call these method each time, the other method is using Theme i will explain this next post.
