I've just spent a couple of hours searching the forum but can't find what I want - probably because I don't really know what I want and I am missing the obvious. I'm sure someone has done this before, but I haven't. I've sent intents to choose an app to open a file but I want to do the opposite.
Because the several image viewers I use on Android seem to have a limited maximum zoom level I want to write a very simple app that will appear in the "Open with ..." dialogs of the image viewers and when opened copy the selected file to local storage and view it with my ScaleImageView so that the maximum zoom level is under my control. I can easily do all this once my app opens but I can't fathom out how to get it open. I think I need a static intent filter in the manifest but I don't know what intent and where or how to process it.
Can someone who knows about such things point me to the post or tutorial that I can't find. No doubt I will feel stupid once I see it but I'm a bit baffled at the moment.
