Is it maybe same issue as described below? http://www.androidpolice.com/2014/02/17/external-blues-google-has-brought-big-changes-to-sd-cards-in-kitkat-and-even-samsung-may-be-implementing-them/
The documentation you quoted talks about "android.permission.READ_EXTERNAL_STORAGE", and then you went on to write that your app has always had WRITE_EXTERNAL_STORAGE. Perhaps you need the READ permission as well? -- K 2014-02-21 0:19 GMT+04:00 Nathan <nathan.d.mel...@gmail.com>: > Users have reported failures doing operations with an app on the secondary > storage wit (not external storage, the one that is actually external and/or > removable) after receiving an update to Android 4.4. > > Based on logs so far, it appears it may be the result of an app being > given limited or no file access to those storage volumes. > > I do not have the devices in question, so far Galaxy Note 3 and S4. > > I did find the following in Android 4.4 update notes. > > If your app reads from external storage... > > Your app can not read shared files on the external storage when running on > Android 4.4, unless your app has > theREAD_EXTERNAL_STORAGE<https://developer.android.com/reference/android/Manifest.permission.html#READ_EXTERNAL_STORAGE> > permission.
