Solution

  • First You need to find Your topcomponent. You can use this method:

    WindowManager.getDefault().findTopComponent("YourTopComponentPreferredId")

    or You can iterate over the opened topcomponents with this method:

    WindowManager.getDefault().getRegistry().getOpened()

    and select that You need. After You have the TopComponent call open() and requestActive() methods on it.
