public static final int FLAG_ACTIVITY_REORDER_TO_FRONT
Since:
API Level 3
If set in an Intent passed to
Context.startActivity() , this flag will cause the launched activity to be brought to the front of its task's history stack if it is already running. For example, consider a task consisting of four activities: A, B, C, D. If D calls startActivity() with an Intent that resolves to the component of activity B, then B will be brought to the front of the history stack, with this resulting order: A, C, D, B. This flag will be ignored if
FLAG_ACTIVITY_CLEAR_TOP is also specified. Constant Value:
131072 (0x00020000)
