External storage access
You can now read and write app-specific files on secondary external storage media, such as when a device provides both emulated storage and an SD card. The new method getExternalFilesDirs() works the same as the existing getExternalFilesDir() method except it returns an array of File objects. Before reading or writing to any of the paths returned by this method, pass the File object to the new getStorageState() method to verify the storage is currently available.
Other methods for accessing your app-specific cache directory and OBB directory also now have corresponding versions that provide access to secondary storage devices: getExternalCacheDirs() and getObbDirs(), respectively.
The first entry in the returned File array is considered the device's primary external storage, which is the same as the File returned by existing methods such as getExternalFilesDir().
