问题
I want to add some MMS messages into my device database.
I've the following code but it doesn't work at all. No entry are added into the native app...
public static Uri insert(Context context, String[] to, String subject, Uri messageUri)
{
try
{
Uri destUri = Uri.parse("content://mms/sent");
// Get thread id
Set<String> recipients = new HashSet<String>();
recipients.addAll(Arrays.asList(to));
long thread_id = getOrCreateThreadId(context, recipients);
Log.e(">>>>>>>", "Thread ID is " + thread_id);
// Create a dummy sms
ContentValues dummyValues = new ContentValues();
dummyValues.put("thread_id", thread_id);
dummyValues.put("body", "Dummy SMS body.");
Uri dummySms = context.getContentResolver().insert(Uri.parse("content://sms/sent"), dummyValues);
// Create a new message entry
ContentValues mmsValues = new ContentValues();
mmsValues.put("thread_id", thread_id);
mmsValues.put("date", System.currentTimeMillis()/1000);
mmsValues.put("ct_t", "application/vnd.wap.multipart.related");
mmsValues.put("read", "1");
mmsValues.put("sub", subject);
// Create part
long dummyId = System.currentTimeMillis();
createPart(context, dummyId, imageBytes);
// Insert message
Uri res = context.getContentResolver().insert(destUri, mmsValues);
String messageId = res.getLastPathSegment().trim();
Log.e(">>>>>>>", "Message saved as " + res);
// Update part
ContentValues updateValues = new ContentValues();
updateValues.put("mid", messageId);
Uri updateUri = Uri.parse("content://mms/" + dummyId + "/part");
int mmsPartRows = context.getContentResolver().update(updateUri, updateValues, null, null);
Log.e(">>>>>>>", "Part rows " + mmsPartRows);
// Create addresses
for (String addr : to)
{
ContentValues addrValues = new ContentValues();
addrValues.put("address", addr);
addrValues.put("charset", "106");
addrValues.put("type", 151); // TO
Uri addrUri = Uri.parse("content://mms/"+ messageId +"/addr");
Uri mmsAddrUri = context.getContentResolver().insert(addrUri, addrValues);
Log.e(">>>>>>>", "Addr uri is " + mmsAddrUri.toString());
}
res = Uri.parse(destUri + "/" + messageId);
// Delete dummy sms
context.getContentResolver().delete(dummySms, null, null);
return res;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
private static Uri createPart(Context context, long id, byte[] imageBytes) throws Exception
{
ContentValues mmsPartValue = new ContentValues();
mmsPartValue.put("ct", "image/png");
Uri partUri = Uri.parse("content://mms/" + id + "/part");
Uri res = context.getContentResolver().insert(partUri, mmsPartValue);
Log.e(">>>>>>>", "Part uri is " + res.toString());
// Add data to part
OutputStream os = context.getContentResolver().openOutputStream(res);
ByteArrayInputStream is = new ByteArrayInputStream(imageBytes);
byte[] buffer = new byte[256];
for (int len=0; (len=is.read(buffer)) != -1;)
{
os.write(buffer, 0, len);
}
os.close();
is.close();
return res;
}
private static long getOrCreateThreadId(Context context, String[] numbers)
{
HashSet<String> recipients = new HashSet<String>();
recipients.addAll(Arrays.asList(numbers));
return Telephony.Threads.getOrCreateThreadId(context, recipients);
}
contextis my view contexttois a string array containing the addresses (eg. new String[] {"0612345678", "0623456789"})subjectis my MMS subject such as "Sent via MyApp"messageUriis an Uri pointing to the image I want to send on my SD card.
Am I doing it wrong ?

Finally I found how to do the job ! Here is the code I made.
Tell me if you got some troubles with this.
public static Uri insert(Context context, String[] to, String subject, byte[] imageBytes)
{
try
{
Uri destUri = Uri.parse("content://mms");
// Get thread id
Set<String> recipients = new HashSet<String>();
recipients.addAll(Arrays.asList(to));
long thread_id = getOrCreateThreadId(context, recipients);
Log.e(">>>>>>>", "Thread ID is " + thread_id);
// Create a dummy sms
ContentValues dummyValues = new ContentValues();
dummyValues.put("thread_id", thread_id);
dummyValues.put("body", "Dummy SMS body.");
Uri dummySms = context.getContentResolver().insert(Uri.parse("content://sms/sent"), dummyValues);
// Create a new message entry
long now = System.currentTimeMillis();
ContentValues mmsValues = new ContentValues();
mmsValues.put("thread_id", thread_id);
mmsValues.put("date", now/1000L);
mmsValues.put("msg_box", MESSAGE_TYPE_OUTBOX);
//mmsValues.put("m_id", System.currentTimeMillis());
mmsValues.put("read", 1);
mmsValues.put("sub", subject);
mmsValues.put("sub_cs", 106);
mmsValues.put("ct_t", "application/vnd.wap.multipart.related");
mmsValues.put("exp", imageBytes.length);
mmsValues.put("m_cls", "personal");
mmsValues.put("m_type", 128); // 132 (RETRIEVE CONF) 130 (NOTIF IND) 128 (SEND REQ)
mmsValues.put("v", 19);
mmsValues.put("pri", 129);
mmsValues.put("tr_id", "T"+ Long.toHexString(now));
mmsValues.put("resp_st", 128);
// Insert message
Uri res = context.getContentResolver().insert(destUri, mmsValues);
String messageId = res.getLastPathSegment().trim();
Log.e(">>>>>>>", "Message saved as " + res);
// Create part
createPart(context, messageId, imageBytes);
// Create addresses
for (String addr : to)
{
createAddr(context, messageId, addr);
}
//res = Uri.parse(destUri + "/" + messageId);
// Delete dummy sms
context.getContentResolver().delete(dummySms, null, null);
return res;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
private static Uri createPart(Context context, String id, byte[] imageBytes) throws Exception
{
ContentValues mmsPartValue = new ContentValues();
mmsPartValue.put("mid", id);
mmsPartValue.put("ct", "image/png");
mmsPartValue.put("cid", "<" + System.currentTimeMillis() + ">");
Uri partUri = Uri.parse("content://mms/" + id + "/part");
Uri res = context.getContentResolver().insert(partUri, mmsPartValue);
Log.e(">>>>>>>", "Part uri is " + res.toString());
// Add data to part
OutputStream os = context.getContentResolver().openOutputStream(res);
ByteArrayInputStream is = new ByteArrayInputStream(imageBytes);
byte[] buffer = new byte[256];
for (int len=0; (len=is.read(buffer)) != -1;)
{
os.write(buffer, 0, len);
}
os.close();
is.close();
return res;
}
private static Uri createAddr(Context context, String id, String addr) throws Exception
{
ContentValues addrValues = new ContentValues();
addrValues.put("address", addr);
addrValues.put("charset", "106");
addrValues.put("type", 151); // TO
Uri addrUri = Uri.parse("content://mms/"+ id +"/addr");
Uri res = context.getContentResolver().insert(addrUri, addrValues);
Log.e(">>>>>>>", "Addr uri is " + res.toString());
return res;
}

you may want to read "how to get image from mms" in the following link. Note that it is using a bitmap to get the image , rather than a ContentResolver.
see Here go to accepted answer , searching for text string above that is bolded
