How to select and crop an image in android?

Question

Hey, I am currently working on a live wallpaper and I allow the user to select an image which will go behind my effects.

Currently I have:

Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            i.putExtra("crop", "true");
            startActivityForResult(i, 1);

And slightly under that:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      if (requestCode == 1)
        if (resultCode == Activity.RESULT_OK) {
          Uri selectedImage = data.getData();
          Log.d("IMAGE SEL", "" + selectedImage);
          // TODO Do something with the select image URI
          SharedPreferences customSharedPreference = getSharedPreferences("imagePref", Activity.MODE_PRIVATE);
          SharedPreferences.Editor editor = customSharedPreference.edit();
          Log.d("HO", "" + selectedImage);
          editor.putString("imagePref", getRealPathFromURI(selectedImage));
          Log.d("IMAGE SEL", getRealPathFromURI(selectedImage));
          editor.commit();
        } 
    }

When my code is ran, Logcat tells me that selectedImage is null. If I comment out the

i.putExtra("crop", "true"):

Logcat does not give me the null pointer exception, and I am able to do what I want with the image. So, what is the problem here? Does any one have any idea how I can fix this? Thanks, for your time.

Apparently this functionality is undocumented and this "implementation detail" is no longer available in version 2:
