If the user specifies a name, we request for the SharedPreferences with that name; if not, we request the default SharedPreference object. Unfortunately, there is no way to get a single list of all SharedPreferences files stored by your app.

You could also save your SharedPreferences names in the default file. If you need to store user preferences, you may want to use the PreferenceActivity or PreferenceFragment command. Just remember that they both use Shared Preferences, too. There are plenty of times where you may need to persist data, but you find Shared Preferences too limiting.

For example, you may need to persist objects or images in Java. You might also need to persist your data logically with the file system hierarchy.

This is where internal storage comes in. Using internal storage is similar to saving with any other file system. You can get references to File objects, and you can store data of virtually any type using a FileOutputStream. What sets it apart is the fact that its contents are only accessible by your app. To get access to your internal file directory, use the Context getFilesDir method.

To create or access a directory within this internal file directory, use the getDir directoryName, Context. In the sample above, if the user-specified filename is empty, we get the base internal storage directory. If the user specifies a name, we get the named directory, creating first if needed.

To read files, use your preferred file reading method. For our example, we read the complete file using a Scanner object. Similarly, to access a file for writing directly within the Internal Storage directory, use the openFileOutput fileName method. To save files, we use the FileOutputStream write. As you can see in the image above, the file path is in a folder not accessible by the file manager or other apps.

The only exception to this will be if you have a rooted device. ProgressDialog ; import android. Context ; import android. PackageManager ; import android. Uri ; import android. AsyncTask ; import android. Environment ; import android.
