I know it is possible to get the contact's photo using something like:

public InputStream getContactPhotoInputStream() throws IOException {
        Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(mContactId));
        InputStream is = ContactsContract.Contacts.openContactPhotoInputStream(contentResolver, uri);

        return is;
}

But now I need to access all RawContact's photo (the one that have one). But I can't. From ContactsContract.RawContacts.DisplayPhoto documentation, the photo is saved as a file and the thumbnail is saved as a Blob in the Data table. I can get the thumbnail photo with simple query to the database and retrieve the Blob but now I need the original size photo and I can't find a way to get it. I can't find any info on android documentation neither on google.

I tried this method (adapted from the save photo file) to get the photo file but to no success.

public InputStream getRawContactPhotoInputStream() throws IOException
    {
        Uri rawContactPhotoUri = Uri.withAppendedPath(
                ContentUris.withAppendedId(RawContacts.CONTENT_URI, Long.parseLong(mRawContactId)),
                RawContacts.DisplayPhoto.CONTENT_DIRECTORY);

        AssetFileDescriptor fd = contentResolver.openAssetFileDescriptor(rawContactPhotoUri, "rw");
        InputStream is = fd.createInputStream();

        fd.close();

        return is;

    }

I get this on LogCat:

Soluzione

After a lot of digging around, looking android's source code exhaustively, I found a way to get the image from a raw contact.

Using Android's native code to get it, I did my own solution (my problem was getting the raw contact's image URI, I couldn't find a way to get it). So from here public static boolean savePhotoFromUriToUr I did this:

public InputStream getBitmapFromUri(String rawContactId) throws FileNotFoundException {

        final Uri photoUri = Uri.withAppendedPath(
                ContentUris.withAppendedId(RawContacts.CONTENT_URI, Long.valueOf(rawContactId)), RawContacts.DisplayPhoto.CONTENT_DIRECTORY);
        final InputStream imageStream = contentResolver.openInputStream(photoUri);

        return imageStream;
}

So here it is, how to get the raw contact's photo.
