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

This solution worked for me with Uri:

Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
intent.setDataAndType(contentUri, "image/*");
intent.putExtra("mimeType", "image/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(
                        intent, "Set as:"));

Answer 2

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.

Answer 3

This worked for me :

Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
intent.addCategory(Intent.CATEGORY_DEFAULT);
//can't use normal URI, because it requires the Uri from file
intent.setDataAndType(Uri.fromFile(new File(uriOfImage)),"image/*");
intent.putExtra("mimeType","image/*");
startActivity(Intent.createChooser(intent,"Set Image"));

You can check that the URI that you pass, should contain the 'file://' prefix (It doesn't work without that).
