I want to fetch and view sms conversations?

You can fetch sms-inbox:

Uri mSmsinboxQueryUri = Uri.parse("content://sms/inbox");
Cursor cursor1 = getContentResolver().query(mSmsinboxQueryUri,new String[] { "_id", "thread_id", "address", "person", "date","body", "type" }, null, null, null);
startManagingCursor(cursor1);
String[] columns = new String[] { "address", "person", "date", "body","type" };
if (cursor1.getCount() > 0) {
   String count = Integer.toString(cursor1.getCount());
   while (cursor1.moveToNext()){
       String address = cursor1.getString(cursor1.getColumnIndex(columns[0]));
       String name = cursor1.getString(cursor1.getColumnIndex(columns[1]));
       String date = cursor1.getString(cursor1.getColumnIndex(columns[2]));
       String msg = cursor1.getString(cursor1.getColumnIndex(columns[3]));
       String type = cursor1.getString(cursor1.getColumnIndex(columns[4]));
    }
}

You can fetch other sent items by changing the URI.

Uri mSmsinboxQueryUri = Uri.parse("content://sms/sent");

You can do that with MMS also with URI:

RECEIVED_MMS_CONTENT_URI = "content://mms/inbox";
SENT_MMS_CONTENT_URI = "content://mms/sent";

For SMS-MMS both:

Uri uri = Uri.parse("content://mms-sms/conversations/");

finally got what i needed!

ContentResolver contentResolver = getContentResolver();
final String[] projection = new String[]{"*"};
Uri uri = Uri.parse("content://mms-sms/conversations/");
Cursor query = contentResolver.query(uri, projection, null, null, null);
