How to start the “set as” intent (wallpaper, contact picture, etc)

Question

I searched over the web during the last few weeks (seriously) but I can\'t find what I need. I just would like to start an intent corresponding to the set as

Answer 1

I found the answer by my self :

Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
intent.setDataAndType(imageUri, "image/*");
intent.putExtra("jpg", "image/*");
startActivityForResult(Intent.createChooser(intent,
getString(R.string.set_as)), REQUEST_ID_SET_AS_WALLPAPER);

You just have to ensure that the uri is public and will be reachable by the crop application chosen by the user.
