  1. static final int DBX_CHOOSER_REQUEST = 0;    
  2. private Button mChooserButton;    
  3. private DbxChooser mChooser;    
  4. @Override    
  5. protected void onCreate(Bundle savedInstanceState)    
  6. {    
  7.     super.onCreate(savedInstanceState);    
  8.     setContentView(R.layout.activity_main);    
  9.     mChooser = new DbxChooser(APP_KEY);    
  10.     mChooserButton = (Button) findViewById(R.id.chooser_button);    
  11.     mChooserButton.setOnClickListener(new OnClickListener()    
  12.     {    
  13.         @Override    
  14.         public void onClick(View v)    
  15.         {    
  16.             mChooser.forResultType(DbxChooser.ResultType.PREVIEW_LINK).launch(MainActivity.this, DBX_CHOOSER_REQUEST);    
  17.         }    
  18.     });

    1. @Override    
    2. public void onActivityResult(int requestCode, int resultCode, Intent data)    
    3. {    
    4.     if (requestCode == DBX_CHOOSER_REQUEST)    
    5.     {    
    6.         if (resultCode == Activity.RESULT_OK)    
    7.         {    
    8.             DbxChooser.Result result = new DbxChooser.Result(data);    
    9.             Log.d("main""Link to selected file: " + result.getLink()); // Handle the result     
    10.         } else     
    11.         {    
    12.             // Failed or was cancelled by the user.     
    13.         }    
    14.     } else    
    15.     {    
    16.         super.onActivityResult(requestCode, resultCode, data);
