Storing files on SD card in Android

I would like to store a file on the SD card. According to the Android docs, SharedPreference can help to retrieve key-value pairs of primitive data types. However, it stores files in the internal storage.

Is there a class with similar functionality to SharedPreference but which can store a file on the SD card?

You first need to check if the SD card is accessable with:

File sdDir = Environment.getExternalStorageDirectory();

Do not forget to put below in your Manifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

You can then use something like this:

File file = new File(root, "/sdcard/test.txt");             
FileWriter fwriter = new FileWriter(file);             
BufferedWriter out = new BufferedWriter(fwriter);             
out.write("Hello world");             
out.close();
