I’ve been working on the “installed” version of my app. By Installed, I mean on windows 10, for example, add to desktop feature of chrome.
When running in chrome browser, I use
window.open(Photo URL)
and a related tab opens in chrome with, in my case, the photo from a gallery selection.
However, when the user installs my app on windows 10 specifically (eg, not android) and the user selects a photo, it opens the chrome browser as another window to view it. It’s not associated to the standalone app chrome instance.
As a web app not installed on all devices, the photo opens a new chrome tab in the same chrome instance which the back button can close, and chrome takes you back to the app page.
I think what I was looking for, was for a way, when I detect standalone, to display the photo in the chrome app. But I don’t know how to open a window “in the app”, or somehow associated with it, so when that photo window is closed (or the back button pressed), that I return to the app.
