Question

I have navigated to maps application from myapplication using following code

Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

1. when i press back button in maps it navigates to my application.
2. When i minimize maps application and open maps from recently open list apps and press back button, My application is not opening.

Could any help me on this ?

Do i need to add any flags to intent to open my application in second case ? or any idea please suggest me..

It seems to me you should set android:alwaysRetainTaskState true in your root activity.
