android - How to access External Micro SD card of the phone?

Question

Does anyone know how can I get SD card of the phone?

I know that someone will tell me its getExternalStorageDirectory() or Environment.getExternalStoragePublicDirectory().

But unfortunately it doesn't always point to the external SD card in all the models. For example I tried in one model of samsung it works fine but another not, LG not. And also according to the documentation also its not always external SD card.

Here it is,

*"don't be confused by the word "external" here.

This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions).

Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer."*

In my application I want user to use SD card only.

How can I overcome with this?

Check out the answer by CommonsWare on the same topic https://stackoverflow.com/a/5695129/582571

He mention that we can not distinguish between mobile's inbuilt external storage and removable external storage.

But by Aleadam answer https://stackoverflow.com/a/6049446/582571 we can only check that is the External Storage is removable or not with isExternalStorageRemovable() function.

I hope you will get idea.
