Animation transition between activities using FLAG_ACTIVITY_CLEAR_TOP

CoolMcGrr is right, you want to use overridePendingTransition(int enterAnim, int exitAnim).

To specifically get the standard "back button" transition, I use these as the enterAnim and exitAnim transitions:

push_right_in.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <translate android:fromXDelta="-100%p" android:toXDelta="0" android:duration="@android:integer/config_shortAnimTime"/>    <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="@android:integer/config_shortAnimTime" /></set>

push_right_out.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <translate android:fromXDelta="0" android:toXDelta="100%p" android:duration="@android:integer/config_shortAnimTime"/>    <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="@android:integer/config_shortAnimTime" /></set>

You should take a look Activity.overridePendingTransition().

Of course, this requires that you run at least version 2.0 of the SDK.

Problem occurs nowadays because pre-ICS and ICS have different built-in activity transitions.This is much cleaner than defining your own animation and SDK independant:

Intent intent = new Intent(this, MMConnection.class);intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_NO_ANIMATION);this.startActivity(intent);finish();

This will start the activity (not visible yet) and play the "activity finish" transition to the new activity.
