Delete file on SD card on Android 4.4 -

it known if have on android 4.4.4 file on sd card in folder not include app package name file cannot deleted.

is there way delete such file?

nasty workaround exists (see code below). tested on samsung galaxy s4, fix does't work on devices. wouldn’t count on workaround being available in future versions of android.

there great article explaining (4.4+) external storage permissions change.

you can read more workaround here. workaround source code this site.
