Apps are supposed to ask the user (just like Amaze does if you try to modify a file on SD card). It’s also possible (with root) to circumvent this by using adb to pull /system/etc/permissions/platform.xml from your phone :

adb pull /system/etc/permissions/platform.xml

edit it by turning

    <permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
        <group gid="sdcard_r" />
        <group gid="sdcard_rw" />
    </permission>

into

    <permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
        <group gid="sdcard_r" />
        <group gid="sdcard_rw" />
        <group gid="media_rw" />
    </permission>

then re-push it to your phone

adb push platform.xml /system/etc/permissions/platform.xml

Then reboot your phone. You might have to adb remount before you push though.
