Android getting external storage Absolute Path

Question

I want to download some files and save them into the internal storage of the phone/tab. Tried on Samsung Galaxy Note 2 and Galaxt Tab 10.1. When I use /storage/sdcard0/ on them the code runs successfully but when I use Galaxy Nexus 3 the code fails.

I want to get absolute path of the phoe or tab's internal storage' Absolute Path.

Does it possible, if so how?

When I use /storage/sdcard0/ on them the code runs successfully but when I use Galaxy Nexus 3 the code fails.

/storage/sdcard0/ is not internal storage. It is external storage.

(BTW, since there is no device named "Galaxy Nexus 3", I am assuming that you simply meant "Galaxy Nexus")

To find locations on internal storage for your app, use getFilesDir(), called on any Context (such as your Activity, to get a File object.

To get a location on external storage unique for your app, use getExternalFilesDir(), called on any Context (such as your Activity, to get a File object.

To get a standard location on external storage for common types of files (e.g., movies), use getExternalStoragePublicDirectory() on Environment.

To get the root of external storage, use getExternalStorageDirectory() on Environment. This, however, is considered sloppy programming nowadays, as it encourages developers to just put files in random locations.
