问题
I\'m having trouble loading a photo for a contact in Android. I\'ve googled for an answer, but so far have come up empty. Does anyone have an example of querying for a Contact, then loading the Photo?
So, given a contactUri which comes from an Activity result called using
startActivityForResult(new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI),PICK_CONTACT_REQUEST)
is:
content://com.android.contacts/data/1557
The loadContact(..) works fine. However when I call the getPhoto(...) method, I get a null value for the photo InputStream. It is also confusing because the URI values are different. The contactPhotoUri evaluates to:
content://com.android.contacts/contacts/1557
See the comments inline in the code below.
class ContactAccessor {
/**
* Retrieves the contact information.
*/
public ContactInfo loadContact(ContentResolver contentResolver, Uri contactUri) {
//contactUri --> content://com.android.contacts/data/1557
ContactInfo contactInfo = new ContactInfo();
// Load the display name for the specified person
Cursor cursor = contentResolver.query(contactUri,
new String[]{Contacts._ID,
Contacts.DISPLAY_NAME,
Phone.NUMBER,
Contacts.PHOTO_ID}, null, null, null);
try {
if (cursor.moveToFirst()) {
contactInfo.setId(cursor.getLong(0));
contactInfo.setDisplayName(cursor.getString(1));
contactInfo.setPhoneNumber(cursor.getString(2));
}
} finally {
cursor.close();
}
return contactInfo; // <-- returns info for contact
}
public Bitmap getPhoto(ContentResolver contentResolver, Long contactId) {
Uri contactPhotoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
// contactPhotoUri --> content://com.android.contacts/contacts/1557
InputStream photoDataStream = Contacts.openContactPhotoInputStream(contentResolver,contactPhotoUri); // <-- always null
Bitmap photo = BitmapFactory.decodeStream(photoDataStream);
return photo;
}
public class ContactInfo {
private long id;
private String displayName;
private String phoneNumber;
private Uri photoUri;
public void setDisplayName(String displayName) {
this.displayName = displayName;
}
public String getDisplayName() {
return displayName;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getPhoneNumber() {
return phoneNumber;
}
public Uri getPhotoUri() {
return this.photoUri;
}
public void setPhotoUri(Uri photoUri) {
this.photoUri = photoUri;
}
public long getId() {
return this.id;
}
public void setId(long id) {
this.id = id;
}
}
}
Clearly, I\'m doing something wrong here, but I can\'t seem to figure out what the problem is. Thanks.

Having scanned the many questions and answers to the problem of displaying a thumbnail I thought I would post my solution to this particular conundrum as I could only find a couple that worked at all and none that provided a good canned solution for the lazy developer.
The class below takes a Context, QuickContactBadge and a telephone number and will attach a locally stored image to the badge if there is one available for the specified phone number.
Here's the class:
public final class QuickContactHelper {
private static final String[] PHOTO_ID_PROJECTION = new String[] {
ContactsContract.Contacts.PHOTO_ID
};
private static final String[] PHOTO_BITMAP_PROJECTION = new String[] {
ContactsContract.CommonDataKinds.Photo.PHOTO
};
private final QuickContactBadge badge;
private final String phoneNumber;
private final ContentResolver contentResolver;
public QuickContactHelper(final Context context, final QuickContactBadge badge, final String phoneNumber) {
this.badge = badge;
this.phoneNumber = phoneNumber;
contentResolver = context.getContentResolver();
}
public void addThumbnail() {
final Integer thumbnailId = fetchThumbnailId();
if (thumbnailId != null) {
final Bitmap thumbnail = fetchThumbnail(thumbnailId);
if (thumbnail != null) {
badge.setImageBitmap(thumbnail);
}
}
}
private Integer fetchThumbnailId() {
final Uri uri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
final Cursor cursor = contentResolver.query(uri, PHOTO_ID_PROJECTION, null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
try {
Integer thumbnailId = null;
if (cursor.moveToFirst()) {
thumbnailId = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
}
return thumbnailId;
}
finally {
cursor.close();
}
}
final Bitmap fetchThumbnail(final int thumbnailId) {
final Uri uri = ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, thumbnailId);
final Cursor cursor = contentResolver.query(uri, PHOTO_BITMAP_PROJECTION, null, null, null);
try {
Bitmap thumbnail = null;
if (cursor.moveToFirst()) {
final byte[] thumbnailBytes = cursor.getBlob(0);
if (thumbnailBytes != null) {
thumbnail = BitmapFactory.decodeByteArray(thumbnailBytes, 0, thumbnailBytes.length);
}
}
return thumbnail;
}
finally {
cursor.close();
}
}
}
And here's a typical use case inside an activity:
String phoneNumber = "...";
QuickContactBadge badge = (QuickContactBadge) view.findViewById(R.id.friend);
new QuickContactHelper(this, badge, phoneNumber).addThumbnail();
In a fragment it will be slightly different:
String phoneNumber = "...";
QuickContactBadge badge = (QuickContactBadge) view.findViewById(R.id.friend);
new QuickContactHelper(getActivity(), badge, phoneNumber).addThumbnail();
Now there are ways to be more efficient - for example if you are rendering a message timeline you'd want to re-use the same bitmap object for every badge instance for a given phone number instead of constantly creating new helper class instances and re-retrieving the bitmap - but my purpose here was to post a solution that is stripped down to the absolute minimum for clarity whilst at the same time providing a complete and usable solution out of the box. This solution has been built and tested on Andriod 4.0, and tested on 4.1 as well.

This works for me:
public static Bitmap loadContactPhoto(ContentResolver cr, long id) {
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
if (input == null) {
return null;
}
return BitmapFactory.decodeStream(input);
}

Guys, I spent many hours attempting to figure this out. Here is a method I created that will get you your facebook photo by phone number (no dashes). You can, of course, modify it accordingly:
public Bitmap getFacebookPhoto(String phoneNumber) {
Uri phoneUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Uri photoUri = null;
ContentResolver cr = this.getContentResolver();
Cursor contact = cr.query(phoneUri,
new String[] { ContactsContract.Contacts._ID }, null, null, null);
if (contact.moveToFirst()) {
long userId = contact.getLong(contact.getColumnIndex(ContactsContract.Contacts._ID));
photoUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, userId);
}
else {
Bitmap defaultPhoto = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_menu_report_image);
return defaultPhoto;
}
if (photoUri != null) {
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(
cr, photoUri);
if (input != null) {
return BitmapFactory.decodeStream(input);
}
} else {
Bitmap defaultPhoto = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_menu_report_image);
return defaultPhoto;
}
Bitmap defaultPhoto = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_menu_report_image);
return defaultPhoto;
}

After a lot of debugging nights I discover that the best approach is to use the contact id and if it fails to use the photo id.
public static Bitmap loadContactPhoto(ContentResolver cr, long id,long photo_id)
{
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
if (input != null)
{
return BitmapFactory.decodeStream(input);
}
else
{
Log.d("PHOTO","first try failed to load photo");
}
byte[] photoBytes = null;
Uri photoUri = ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, photo_id);
Cursor c = cr.query(photoUri, new String[] {ContactsContract.CommonDataKinds.Photo.PHOTO}, null, null, null);
try
{
if (c.moveToFirst())
photoBytes = c.getBlob(0);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
} finally {
c.close();
}
if (photoBytes != null)
return BitmapFactory.decodeByteArray(photoBytes,0,photoBytes.length);
else
Log.d("PHOTO","second try also failed");
return null;
}
the code tested on emulator and Nexus S device and seems to work.

None of these approaches worked for me. What did work was:
String[] projection = new String[] {
ContactsContract.Contacts.PHOTO_ID, ///< the correct ID for photo retrieval in loadLocalContactPhotoBytes()
// ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
// ContactsContract.CommonDataKinds.Photo.PHOTO
};
ContentResolver cr = ctx.getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
// Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
// new String[] {RawContacts._ID, RawContacts.ACCOUNT_TYPE, RawContacts.ACCOUNT_NAME},
// new String[] {Contacts._ID},
projection, null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
....
//the 'cursor' above got passed as an argument below
private byte[] loadLocalContactPhotoBytes(ContentResolver cr, Cursor cursor, byte[] defaultPhotoBytes)
{
byte[] photoBytes = null;// = cursor.getBlob(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Photo.PHOTO));
// int id = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts._ID));
int id = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
// Uri contactUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
// Uri photoUri = Uri.withAppendedPath(contactUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
Uri photoUri = ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, id);
Cursor c = cr.query(photoUri, new String[] {ContactsContract.CommonDataKinds.Photo.PHOTO}, null, null, null);
try
{
if (c.moveToFirst())
photoBytes = c.getBlob(0);
} catch (Exception e) {
// TODO: handle exception
Log.w(_TAG, e.toString());
} finally {
c.close();
}
photoBytes = photoBytes == null ? defaultPhotoBytes : photoBytes;
return photoBytes;
}

Just for kicks I copied most of the answers here into a single class to see if any of them would succeed in getting the Facebook thumbnail. They didn't.... But, here is what I did to perhaps save you doing the same.
It shows the results in a dialog for ease.
Please be aware - it's not optimised and you'll need to catch errors and close cursors etc:
To start the contact picker intent:
private static final int SELECT_CONTACT = 1468;
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
contactPickerIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
try {
startActivityForResult(contactPickerIntent, SELECT_CONTACT);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
The callback:
@Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (data != null && resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case SELECT_CONTACT:
Uri contactURI = data.getData();
if (contactURI != null) {
String contactID = data.getData().getLastPathSegment().trim();
String contactName = ContactThumb.getDisplayName(getActivity(), contactURI);
if (contactName != null && !contactName.isEmpty() && contactID != null && !contactID.isEmpty()) {
final int THUMBNAIL_SIZE = 100;
Bitmap contactThumb = ContactThumb.loadContactPhoto(getActivity(), Long.valueOf(contactID));
if (contactThumb != null) {
final AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
final int width = contactThumb.getWidth();
final int height = contactThumb.getHeight();
final int ratio = width / height;
final Bitmap resized = ThumbnailUtils.extractThumbnail(contactThumb, (THUMBNAIL_SIZE * ratio),
THUMBNAIL_SIZE);
Drawable icon = new BitmapDrawable(getActivity().getResources(), resized);
alert.setIcon(icon);
alert.setTitle("Contact details");
final TextView homeTV = new TextView(getActivity());
homeTV.setText(contactName + " : " + contactID);
homeTV.setTextSize(12);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
homeTV.setTextColor(Color.WHITE);
}
homeTV.setPadding(30, 2, 20, 10);
homeTV.setMovementMethod(LinkMovementMethod.getInstance());
alert.setView(homeTV);
alert.show();
} else {
Toast.makeText(getActivity(), "Photo null", Toast.LENGTH_SHORT).show();
}
}
}
break;
}
} else {
// cancelled or error
}
}

It seems that my problem was because the contacts in my device were synced from facebook, and the photo therefore is not available.

Android documentation says, that we should do it in this way.
public Bitmap openPhoto(long contactId) {
Uri contactUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, contactId);
Uri photoUri = Uri.withAppendedPath(contactUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
Cursor cursor = getContentResolver().query(photoUri,
new String[] {ContactsContract.Contacts.Photo.PHOTO}, null, null, null);
if (cursor == null) {

try {
if (cursor.moveToFirst()) {
byte[] data = cursor.getBlob(0);
if (data != null) {
return BitmapFactory.decodeStream(new ByteArrayInputStream(data));
}
}
} finally {
cursor.close();
}
return null;

contactId stands for:
getString(c.getColumnIndex(ContactsContract.Contacts._ID))
