Trying to use the extension pattern this way gets an error when uploading the APK to Google Play, so just hard code the extension patters. This won’t work for PBS kids version.
Don’t export as email message. and be less strict about import requirements.
Android intent filters are really only designed to work with standard mimetypes (like ‘image/png’). Even if you can share something with a custom mime type, it’s likely to get lost somewhere along the way, from email, or Gdrive, or Files app etc.
Path matching patterns in intent filter only apply to `file` schemes, `content` scheme is likely to be some generated id in temp storage. `content` filters maintly go by mimetype, but as noted above, a custom mimetype has often gone AWOL. Generic application files are usually downloaded as `application/octet-stream`. Basically we have to trust the user not to try to load some other random file into ScratchJr. The import function will fail and give an error message if they do.
Finally, fix the way we’re sharing ScratchJr files. While the button says ‘Share by Email’ for a long time Android has shown a selection of ways to share the file. However, we were setting the mime type as an email message so the saved file would always try to open in an email client instead of ScratchJr.
This PR was 95% of the way there, and I didn’t want to ask for changes after not getting to review it for so long, so I just made the changes.
Thanks for submitting!
* Remove ScratchJrApplication class - it was only being used to initialize the old Google Analytics.
* Change AppUsage (home, school, other, noanswer) from being a prefix on `label` to being a Firebase user property.
* Set the user property when loading the index page - it shouldn’t change for the rest of the session.
PBS Kids has automated testing that looks for uses-sdk with a minimum targetSDK of 23. Even though this gets overridden in the build.gradle settings, adding a line with default values to get through their testing.
Changed android:requiresSmallestWidthDp from 600 to 500.
Android suggests that 600 is a normal value for 7 inch tablets and up. It turns out that many 7-inch tablets are in the 500-600 range (half of the Amazon ones for example).
