android - How to open gallery via intent without result?

I have a kind of an ApplicationLauncher that has to start the build-in gallery. But I don't want to get any result from that gallery. I just want to start it and want my "Launcher" to close after that.

What I have tried:

    Intent intentBrowseFiles = new Intent(Intent.ACTION_GET_CONTENT);
    intentBrowseFiles.setType("image/*");
    intentBrowseFiles.setFlag(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intentBrowseFiles);

but it doesn't even work with this flag. As soon as I click on a pic in the gallery, it closes and returns to my "Launcher". Is there any way to achieve what I want to do?

    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_VIEW );
    startActivity(intent);
