Titanium - Android external storage - create new directory and then write files into it

Question

Can we not simply create new directory programmatically on external SD card (not internal memory of device) in Android and can we not write files on SD card?

Is Titanium

Answer 1

You can use System class to get storage variables like below

To get the internal SD card you can use

String extStore = System.getenv("EXTERNAL_STORAGE");
File f_exts = new File(extStore);

To get the external SD card you can use

String secStore = System.getenv("SECONDARY_STORAGE");
File f_secs = new File(secStore);

You can choose where to create folder and which one to use.

EDIT

Environment.getExternalStorageDirectory() Details

• Return the primary shared/external storage directory.
• This directory may not currently be accessible if it has been mounted by the user on their computer, has been removed from the device, or some other problem has happened. You can determine its current state with getExternalStorageState().

Note: 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.
