My android app uses Samsung SPen SDK 2.2. I have > 50 users and > 3 months I did not get any crash reports, but today I got one in Google Play Developer Console. It came from Samsung Galaxy Note 3 (Android 4.3), but there are a lot of other users with the same device never had this problem.
Do you have any idea of what could be the reason of the crash? I don't even know how to reproduce it on my test device.
The app code does NOT work with SD card (nothing like
Environment.getExternalStorageDirectory();
, no hardcoded paths to /mnt/sdcard, etc.), it does not have WRITE_EXTERNAL_STORAGE permission. Also, the app cannot be installed/moved to SD card.
The crash report contains the following stack trace:
java.lang.IllegalArgumentException: Invalid path: /mnt/sdcard
