i have tried using environment.getexternalstoragedirectory(), didn't work too.

update when use environment.getexternalstoragedirectory() writes internal storage , not sd card.

the following permissions should defined outside <application> tag.

<uses-permission android:name="android.permission.write_external_storage" />

<uses-permission android:name="android.permission.read_external_storage" />
