 getExternalStoragePublicDirectory 

This is an internal

External words
StorageVolume this

write die not,
because to deal with a variety of machines,
possible different paths

next check, getExternalStoragePublicDirectory point is to get shared storage, such as music, pictures, etc., right
StorageVolume did not find what it is?
------ For reference only -------------------------- -------------
looking for a long time and found that the memory can be obtained through reflection list
but do not know which is the built-in memory

 StorageManager storageManager = (StorageManager) getSystemService (Context.STORAGE_SERVICE);
try {
Class  [] ParamClasses = {};
Method getVolumePathsMethod = StorageManager.class.getMethod ("getVolumePaths", paramClasses);
getVolumePathsMethod.setAccessible (true);
Object [] params = {};
Object invoke = getVolumePathsMethod.invoke (storageManager, params);
for (int i = 0; i <((String []) invoke). length; i + +) {
System.out.println (((String []) invoke) [i]);
} 

} Catch (NoSuchMethodException e1) {
e1.printStackTrace ();
} Catch (IllegalArgumentException e) {
e.printStackTrace ();
} Catch (IllegalAccessException e) {
e.printStackTrace ();
} Catch (InvocationTargetException e) {
e.printStackTrace ();
}

this argument does not necessarily
For example, my phone can be set to the external memory card as the default memory card
so 0 is the external
