How to directly send a message to a contact through WhatsApp from my app with just one click?

I need to send a message from my app to a selected contact using WhatsApp. I have the contact name, number, ID and the message I want to send. just need to be able to send it without having to pick the contact in WhatsApp or the app to share the message. I´ve tested several approaches but I have´nt found any working solution, the simplest is as follows:

Uri uri = Uri.parse("smsto:" + number);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra("sms_body", "message");
i.setPackage("com.whatsapp");  
startActivity(i);

With this approach the contact is selected automatically but then pops out that contact´s conversation inside WhatsApp and the worst part is that the message isn´t even there. With the message there I would only have to hit send and would be something, even when I need to do it all at once.

Thanks in advance!

PD: Thanks for the answer being root, but thats my last option, I just need to be able to send the message from a non rooted device.

Frankly speaking there's no public API available at this moment to share message for a specific contact. However if you aren't concerned with rooted device then you can follow the steps,

protected void whatsAppSendMessage(String[] paramArrayOfString, String paramString) {
  try {
   Shell shell = Shell.startRootShell();
   int j = paramArrayOfString.length;
   for (int i = 0; i < j; i++) {
    String str3;
    long l1;
    long l2;
    int k;
    String str1;
    String str2;
    Random localRandom = new Random(20L);

    Log.d("AUTO",
      "ps | grep -w 'com.whatsapp' | awk '{print $2}' | xargs kill");
    commandsTestOnClick("ps | grep -w 'com.whatsapp' | awk '{print $2}' | xargs kill");

    str3 = paramArrayOfString[i] + "@s.whatsapp.net";
    l1 = System.currentTimeMillis();
    l2 = l1 / 1000L;
    k = localRandom.nextInt();

    str1 = "sqlite3 /data/data/com.whatsapp/databases/msgstore.db \"INSERT INTO messages (key_remote_jid, key_from_me, key_id, status, needs_push, data, timestamp, MEDIA_URL, media_mime_type, media_wa_type, MEDIA_SIZE, media_name , latitude, longitude, thumb_image, remote_resource, received_timestamp, send_timestamp, receipt_server_timestamp, receipt_device_timestamp, raw_data, media_hash, recipient_count, media_duration, origin)VALUES ('"
      + str3
      + "', 1,'"
      + l2
      + "-"
      + k
      + "', 0,0, '"
      + paramString
      + "',"
      + l1
      + ",'','', '0', 0,'', 0.0,0.0,'','',"
      + l1
      + ", -1, -1, -1,0 ,'',0,0,0); \"";

    str2 = "sqlite3 /data/data/com.whatsapp/databases/msgstore.db \"insert into chat_list (key_remote_jid) select '"
      + str3
      + "' where not exists (select 1 from chat_list where key_remote_jid='"
      + str3 + "');\"";

    str3 = "sqlite3 /data/data/com.whatsapp/databases/msgstore.db \"update chat_list set message_table_id = (select max(messages._id) from messages) where chat_list.key_remote_jid='"
      + str3 + "';\"";

    Log.d("AUTO", str1);
    Log.d("AUTO", str2);
    Log.d("AUTO", str3);

    shell.add(
      new SimpleCommand(
        "chmod 777 /data/data/com.whatsapp/databases/msgstore.db"))
      .waitForFinish();
    shell.add(new SimpleCommand(str1)).waitForFinish();
    shell.add(new SimpleCommand(str2)).waitForFinish();
    shell.add(new SimpleCommand(str3)).waitForFinish();
   }
   shell.close();
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

Tested and works perfectly even without opening the WhatsApp!

You cannot do that as of now, because WhatsApp have not opened their APIs to the developers. The best you can do is as described here.

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(sendIntent);

Its strange, because apparently you can select the contact in iOS by passing some extra params.
