Using new Telephony content provider to read SMS

Question

According to the 4.4 SMS APIs, the new version provides functionality to:

allow apps to read and write SMS and MMS messages on the device

I can't find any information on this functionality, nor any samples in the new SDK. This is what I have so far for reading new incoming messages.

However, I would like to read existing messages stored on the deivce:

// Can I only listen for incoming SMS, or can I read existing stored SMS?
SmsMessage[] smsList = Telephony.Sms.Intents.getMessagesFromIntent(intent);
for(SmsMessage sms : smsList) {
    Log.d("Test", sms.getMessageBody())
}

Please note: I know about using the SMS Content Provider, however this method is unsupported. According to the linked APIs, I should be able to do this in a supported way.

Answer 1

It looks like you would be able to use this class to get it working. The package is Telephony.Sms.Conversations.

Although the following code uses the content provider method, this is now an official API added in API Level 19 (KitKat) for reading the SMS messages.

public List<String> getAllSmsFromProvider() {
  List<String> lstSms = new ArrayList<String>();
  ContentResolver cr = mActivity.getContentResolver();

  Cursor c = cr.query(Telephony.Sms.Inbox.CONTENT_URI, // Official CONTENT_URI from docs
                      new String[] { Telephony.Sms.Inbox.BODY }, // Select body text
                      null,
                      null,
                      Telephony.Sms.Inbox.DEFAULT_SORT_ORDER); // Default sort order

  int totalSMS = c.getCount();

  if (c.moveToFirst()) {
      for (int i = 0; i < totalSMS; i++) {
          lstSms.add(c.getString(0));
          c.moveToNext();
      }
  } else {
      throw new RuntimeException("You have no SMS in Inbox"); 
  }
  c.close();

  return lstSms;
}

I did it like the following. Create SMSObject:

public class SMSObject {
  private String _id;
  private String _address;
  private String _msg;
  private String _readState; // "0" for have not read sms and "1" for have
                            // read sms
  private String _time;
  private String _folderName;

  //+ getter and setter methods and 

  @Override
  public String toString() {
    return "SMSObject [_id=" + _id + ", _address=" + _address + ", _msg="
            + _msg + ", _readState=" + _readState + ", _time=" + _time
            + ", _folderName=" + _folderName + "]";
}

And here a simple function, which simply logs all current SMS-Objects

private void readSMS() {
    List<SMSObject> lstSms = new ArrayList<SMSObject>();
    SMSObject objSms = new SMSObject();
    Uri message = Uri.parse("content://sms/");
    ContentResolver cr = this.getContentResolver();

    Cursor c = cr.query(message, null, null, null, null);
    // this.startManagingCursor(c);
    int totalSMS = c.getCount();
    Log.d("SMS Count->", "" + totalSMS);
    if (c.moveToFirst()) {
        for (int i = 0; i < totalSMS; i++) {

            objSms = new SMSObject();
            objSms.setId(c.getString(c.getColumnIndexOrThrow("_id")));
            objSms.setAddress(c.getString(c
                    .getColumnIndexOrThrow("address")));
            objSms.setMsg(c.getString(c.getColumnIndexOrThrow("body")));
            objSms.setReadState(c.getString(c.getColumnIndex("read")));
            objSms.setTime(c.getString(c.getColumnIndexOrThrow("date")));
            if (c.getString(c.getColumnIndexOrThrow("type")).contains("1")) {
                objSms.setFolderName("inbox");
            } else {
                objSms.setFolderName("sent");
            }

            lstSms.add(objSms);

            Log.d("SMS at " + i, objSms.toString());

            c.moveToNext();
        }
    }
    // else {
    // throw new RuntimeException("You have no SMS");
    // }
    c.close();

    // return lstSms;

}
