Android: Require manual close after installation is complete

When there were some issues during installation, marked with
red lines, it could happen that the user haven't got a chance to
read them, as the dialog was automatically closed after
the installation was done.

To fix it, hide Cancel button on installation finish, show
Close button instead and prolong the visibility of the dialog until
the Close button is pressed.
