Android Browser Dialog with Root Support

I was in the middle of coding some application for android and I needed a File/Folder browsing dialog. But I also needed access to /data and other sensitive folders. So I started searching internet, but I didn't find anything useful. Anyway, I decided to write my own. For initial code, I used sample project from here

I started expanding it, made some changes to it, added images for files and folders, added root access features, added known filetype icons, etc.

Anyway, full project is here

Even thought I've included sample project, I'll explain shortly how you can implement it in your own projects:

1) Add DirectoryPick project as a reference to your own project. (Right click on Project -> Properties -> Android -> Scroll down to Library part -> Click Add -> Choose DirectoryPick and press OK)

2) Add custom permissions DirectoryPick will need to your AndroidManifest.xml:

3) Add activity for DirectoryPick dialog:


4) Add code for starting the dialog:

Intent intent = new Intent(this, DirectoryPicker.class); 
intent.putExtra(DirectoryPicker.USE_ROOT, true); 
intent.putExtra(DirectoryPicker.USE_ROOT, false); 
intent.putExtra(DirectoryPicker.ONLY_DIRS, false); 
intent.putExtra(DirectoryPicker.ONLY_DIRS, true);
intent.putExtra(DirectoryPicker.START_DIR, "/"); 
startActivityForResult(intent, DirectoryPicker.PICK_DIRECTORY); 

5) Add code for retrieving results:

public void onActivityResult(int requestCode, int resultCode, Intent data)
if(requestCode == DirectoryPicker.PICK_DIRECTORY && resultCode == RESULT_OK)
Bundle extras = data.getExtras();
String path = (String) extras.get(DirectoryPicker.CHOSEN_DIRECTORY); 
if(requestCode == DirectoryPicker.PICK_DIRECTORY && resultCode == RESULT_CANCELED)
{ // User cancelled dialog, nothing selected.
