问题
I have a picture, that is stored into the android phone. I want to be able to change the picture of a contact.
What I've done so far is launch the contact picker, have the user select a contact, and then I get the URI of the selected contact. From this contact, I can get the associated rawContact and I use this code.
Uri rawContactPhotoUri = Uri.withAppendedPath(
ContentUris.withAppendedId(RawContacts.CONTENT_URI, rawContactId),
RawContacts.DisplayPhoto.CONTENT_DIRECTORY);
try {
AssetFileDescriptor fd =
getContentResolver().openAssetFileDescriptor(rawContactPhotoUri, "rw");
OutputStream os = fd.createOutputStream();
os.write(photo);
os.close();
fd.close();
} catch (IOException e) {
// Handle error cases.
}
The problem is, the AssetFIleDescriptor is always empty (when I call length on it, we always get -1).
I'm not asking for the entire solution, just some leads to follow that can help me to get that working. I cannot seem to find this problem already on StackOverflow, so any help would be appreciated.
EDIT
It's always when we ask for question that we find the solution. I want to share it for other
So I gave up on android link and find another one : http://wptrafficanalyzer.in/blog/programatically-adding-contacts-with-photo-using-contacts-provider-in-android-example/
The picture picker return the Uri of the selected contact, so with this you can get the Contact._ID of it :
// This is onActivityResult
final Uri uri = data.getData();
final Cursor cursor1 = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
final long contactId = cursor1.getLong(cursor1.getColumnIndex(Contacts._ID);
cursor1.close();
Then I had to get the RawContactId :
final Cursor cursor2 = getContentResolver().query(RawContacts.CONTENT_URI, null, RawContacts.Contact_ID + "=?", new String[] {String.valueOf(contactId)}, null);
cursor2.moveToFirst();
final long rawContactId = cursor2.getLong(cursor2.getColumnIndex(RawContacts._ID));
cursor2.close();
Then I had to get the Data._ID of the RawContacts (same way as above).
Then I used the ContentProviderOperations :
final ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
.withSelection(Data._ID, dataId),
.withValue(Data.MIMETYPE, ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE)
.withValue(ContactsContract.CommonDataKinds.Photo.PHOTO, byteArrayOfThePicture);
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
And this is working like charm. Hope it helps

String contactId ="10001"; // change it as your IDs
if (mBitmap != null) {
// Picture
try {
ByteArrayOutputStream image = new ByteArrayOutputStream();
