How can I send message to specific contact through WhatsApp from my android app?

Question

I am developing an android app and I need to send a message to specific contact from WhatsApp. I tried this code:

Uri mUri = Uri.parse(\"smsto:+999999999\");

There is a way. Make sure that the contact you are providing must be passed as a string in intent without the prefix "+". Country code should be appended as a prefix to the phone number .

e.g.: '+918547264285' should be passed as '918547264285' . Here '91' in beginning is country code .

Note :Replace the 'YOUR_PHONE_NUMBER' with contact to which you want to send the message.

Here is the snippet :

 Intent sendIntent = new Intent("android.intent.action.MAIN");
 sendIntent.setComponent(new  ComponentName("com.whatsapp","com.whatsapp.Conversation"));
 sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators("YOUR_PHONE_NUMBER")+"@s.whatsapp.net");
 startActivity(sendIntent);
