I'm running drupal 7, with date_ical, calendar, and addtocalendar modules.
I have the calendar running superbly, and the download calendar function works like a charm. Unless you're using an android phone. For some unknown reason, Android and webcal:// don't work well together.
I have the workaround, and all the code necessary. I plan to use Mobile_Detect.php (again, I've already used it successfully in the CorporateClean theme to change the display for mobile devices) to use my alternate code whenever AndroidOS is detected.
The workaround code will contain a link to a free app available at the android/google play store, followed by another link that will download the calendar. (If you're having trouble, feel free to email me, and I'll send you the solution)
But now that I have it, I don't know where to put it. Where is the code that actually generates the 'add to calendar' download button?
