Which way is the best to save file on external storage on Android?

Question

Which way is the best to save file on external storage...

a) new File(Enviroment.getExternalStorageDirectory(), "")

b) new File("/mnt/sdcard/","")

Answer 1

Always use

 Enviroment.getExternalStorageDirectory().getPath()

instead of hard coding as below...

/mnt/sdcard/

If you choose hard coding way then the system will throw you below message...

Do not hardcode "/sdcard/"; use Environment.getExternalStorageDirectory().getPath() instead

Another problem is that SDCard folder name isn't same for all devices...SDCard name different in Some devices.

In samsung devices, it is named external_sd and in this case, the hard coding way will be failed. That's why following way is the best...

File file = new File(Enviroment.getExternalStorageDirectory().getPath(), "");

Answer 2

Enviroment.getExternalStorageDirectory() is the best way to save file into external storage. Take a look at this http://developer.android.com/reference/android/os/Environment.html

Answer 3

Always use

Enviroment.getExternalStorageDirectory() in place of mnt/sdcard/

Answer 4

Enviroment.getExternalStorageDirectory() is the best public API for directly accessing the SD card.

However, you should consider using the new ACTION_CREATE_DOCUMENT intent which allows the user to select a location for saving.

For example, if a device has multiple SD cards, the user can select between them, or they can choose any app participating in the Storage Access Framework.
