I think the answer is a mix of your question and this answer here: https://stackoverflow.com/a/15931345/734687 So I would try the following code:

  1. change ACTION_VIEW to ACTION_SENDTO
  2. set the Uri as you did
  3. set the package to whatsapp
Intent i = new Intent(Intent.ACTION_SENDTO, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp");           // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);

I looked into the Whatsapp manifest and saw that ACTION_SEND is registered to the activity ContactPicker, so that will not help you. However ACTION_SENDTO is registered to the activity com.whatsapp.Conversation which sounds more adequate for your problem.

Whatsapp can work as a replacement for sending SMS, so it should work like SMS. When you do not specify the desired application (via setPackage) Android displays the application picker. Thererfor you should just look at the code for sending SMS via intent and then provide the additional package information.

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

First try just to replace the intent ACTION_SEND to ACTION_SENDTO . If this does not work than provide the additional extra sms_body. If this does not work than try to change the uri.

Update I tried to solve this myself and was not able to find a solution. Whatsapp is opening the chat history, but doesn't take the text and send it. It seems that this functionality is just not implemented.

I have done it!

private void openWhatsApp() {
    String smsNumber = "7****"; // E164 format without '+' sign
    Intent sendIntent = new Intent(Intent.ACTION_SEND);
    sendIntent.setType("text/plain");
    sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
    sendIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix
    sendIntent.setPackage("com.whatsapp");
    if (intent.resolveActivity(getActivity().getPackageManager()) == null) {
        Toast.makeText(this, "Error/n" + e.toString(), Toast.LENGTH_SHORT).show();
        return;    
    }
    startActivity(sendIntent);
}

I found the right way to do this and it's so simple, you only need to read this article: http://howdygeeks.com/send-whatsapp-message-unsaved-number-android/

Source code: phone and message are both String.

    PackageManager packageManager = context.getPackageManager();
    Intent i = new Intent(Intent.ACTION_VIEW);

    try {
        String url = "https://api.whatsapp.com/send?phone="+ phone +"&text=" + URLEncoder.encode(message, "UTF-8");
        i.setPackage("com.whatsapp");
        i.setData(Uri.parse(url));
        if (i.resolveActivity(packageManager) != null) {
            context.startActivity(i);
        }
    } catch (Exception e){
        e.printStackTrace();
    }

Enjoy!

This approach works with WhatsApp Business app as well!

Change package name as sendIntent.setPackage("com.whatsapp.w4b"); for WhatsApp Business.

Great hack Rishabh, thanks a lot, I was looking for this solution since last 3 years.

As per the Rishabh Maurya's answer above, I have implemented this code which is working fine for both text and image sharing on WhatsApp.

Note that in both the cases it opens a whatsapp conversation (if toNumber exists in users whatsapp contact list), but user have to click send button to complete the action. That means it helps in skipping contact selection step.

For text messages

String toNumber = "+91 98765 43210"; // contains spaces.
toNumber = toNumber.replace("+", "").replace(" ", "");

Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("text/plain");
startActivity(sendIntent);

For sharing images

String toNumber = "+91 98765 43210"; // contains spaces.
toNumber = toNumber.replace("+", "").replace(" ", "");

Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(imageFile));
sendIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("image/png");
context.startActivity(sendIntent);

Enjoy WhatsApping!

It lets you open WhatsApp conversation screen for that specific user you are trying to communicate with:

private void openWhatsApp() {
    String smsNumber = "91XXXXXXXX20";
    boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp");
    if (isWhatsappInstalled) {

        Intent sendIntent = new Intent("android.intent.action.MAIN");
        sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation"));
        sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators(smsNumber) + "@s.whatsapp.net");//phone number without "+" prefix

        startActivity(sendIntent);
    } else {
        Uri uri = Uri.parse("market://details?id=com.whatsapp");
        Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
        Toast.makeText(this, "WhatsApp not Installed",
                Toast.LENGTH_SHORT).show();
        startActivity(goToMarket);
    }
}

private boolean whatsappInstalledOrNot(String uri) {
    PackageManager pm = getPackageManager();
    boolean app_installed = false;
    try {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        app_installed = true;
    } catch (PackageManager.NameNotFoundException e) {
        app_installed = false;
    }
    return app_installed;
}

Check out my answer : https://stackoverflow.com/a/40285262/5879376

 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");//phone number without "+" prefix

 startActivity(sendIntent);

This will first search for the specified contact and then open a chat window. And if WhatsApp is not installed then try-catch block handle this.

 String digits = "\\d+";
    Sring mob_num = 987654321;     
    if (mob_num.matches(digits)) 
            {
        try {
              /linking for whatsapp
              Uri uri = Uri.parse("whatsapp://send?phone=+91" + mob_num);
              Intent i = new Intent(Intent.ACTION_VIEW, uri);
              startActivity(i);
            }
            catch (ActivityNotFoundException e){
                    e.printStackTrace();
                    Toast.makeText(this, "WhatsApp not installed.", Toast.LENGTH_SHORT).show();
            }
        }

Whatsapp have its own API

    Intent sendIntent = new Intent("android.intent.action.MAIN");
                        sendIntent.setAction(Intent.ACTION_VIEW);
                        sendIntent.setPackage("com.whatsapp");
                        String url = "https://api.whatsapp.com/send?phone=" + "Phone with international format" + "&text=" + "your message";
                        sendIntent.setData(Uri.parse(url));
                        if(sendIntent.resolveActivity(context.getPackageManager()) != null){
                             startActivity(sendIntent);
                        }

Code updated check added for Activity is available or not.

See this documentation

This is the shortest way

    String mPhoneNumber = "+972505555555";
    mPhoneNumber = mPhoneNumber.replaceAll("+", "").replaceAll(" ", "").replaceAll("-","");
    String mMessage = "Hello world";
    String mSendToWhatsApp = "https://wa.me/" + mPhoneNumber + "?text="+mMessage;
    startActivity(new Intent(Intent.ACTION_VIEW,
            Uri.parse(
                    mSendToWhatsApp
            )));

See also the documentation of WhatsApp

This is now possible through the WhatsApp Business API. Only businesses may apply to use it. This is the only way to directly send messages to phone numbers, without any human interaction.

Sending normal messages is free. It looks like you need to host a MySQL database and the WhatsApp Business Client on your server.

 private void openWhatsApp() {
       //without '+'
        try {
            Intent sendIntent = new Intent("android.intent.action.MAIN");

            //sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation"));
            sendIntent.setAction(Intent.ACTION_SEND);
            sendIntent.setType("text/plain");
            sendIntent.putExtra("jid",whatsappId);
            sendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            sendIntent.setPackage("com.whatsapp");
            startActivity(sendIntent);
        } catch(Exception e) {
            Toast.makeText(this, "Error/n" + e.toString(), Toast.LENGTH_SHORT).show();
            Log.e("Error",e+"")    ;    }
    }
try {
                    String text = "Hello, Admin sir";// Replace with your message.

                    String toNumber = "xxxxxxxxxxxx"; // Replace with mobile phone number without +Sign or leading zeros, but with country code
                    //Suppose your country is India and your phone number is “xxxxxxxxxx”, then you need to send “91xxxxxxxxxx”.


                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("http://api.whatsapp.com/send?phone=" + toNumber + "&text=" + text));
                    context.startActivity(intent);
                } catch (Exception e) {
                    e.printStackTrace();
                    context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=com.whatsapp")));

                }

Check this answer. Here your number start with "91**********".

Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setAction(Intent.ACTION_SEND);

sendIntent.setType("text/plain");                    
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");                   sendIntent.putExtra("jid",PhoneNumberUtils.stripSeparators("91**********")                   + "@s.whatsapp.net");                    
sendIntent.setPackage("com.whatsapp");                    
startActivity(sendIntent);

try this, worked for me ! . Just use intent

   Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(whatsappUrl()));
   startActivity(intent);

Build whatsapp url. add country code in whatsapp phone number https://countrycode.org/

public static String whatsappUrl(){

    final String BASE_URL = "https://api.whatsapp.com/";
    final String WHATSAPP_PHONE_NUMBER = "628123232323";    //'62' is country code for Indonesia
    final String PARAM_PHONE_NUMBER = "phone";
    final String PARAM_TEXT = "text";
    final String TEXT_VALUE = "Hello, How are you ?";

    String newUrl = BASE_URL + "send";

    Uri builtUri = Uri.parse(newUrl).buildUpon()
            .appendQueryParameter(PARAM_PHONE_NUMBER, WHATSAPP_PHONE_NUMBER)
            .appendQueryParameter(PARAM_TEXT, TEXT_VALUE)
            .build();

    return buildUrl(builtUri).toString();
}

public static URL buildUrl(Uri myUri){

    URL finalUrl = null;
    try {
        finalUrl = new URL(myUri.toString());
    } catch (MalformedURLException e) {
        e.printStackTrace();

    }
    return finalUrl;
}

This will first search for the specified contact and then open a chat window.

Note: phone_number and str are variables.

Uri mUri = Uri.parse("https://api.whatsapp.com/send?
phone=" + phone_no + "&text=" + str);
Intent mIntent = new Intent("android.intent.action.VIEW", mUri);
mIntent.setPackage("com.whatsapp");
startActivity(mIntent);
Bitmap bmp = null;
            bmp = ((BitmapDrawable) tmpimg.getDrawable()).getBitmap();
            Uri bmpUri = null;
            try {
                File file = new File(getBaseContext().getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".jpg");
                FileOutputStream out = new FileOutputStream(file);
                bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
                out.close();
                bmpUri = Uri.fromFile(file);

            } catch (IOException e) {
                e.printStackTrace();
            }

            String toNumber = "+919999999999"; 
            toNumber = toNumber.replace("+", "").replace(" ", "");
            Intent shareIntent =new Intent("android.intent.action.MAIN");
            shareIntent.setAction(Intent.ACTION_SEND);
            String ExtraText;
            ExtraText =  "Share Text";
            shareIntent.putExtra(Intent.EXTRA_TEXT, ExtraText);
            shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
            shareIntent.setType("image/jpg");
            shareIntent.setPackage("com.whatsapp");
            shareIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
            shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            try {

                startActivity(shareIntent);
            } catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(getBaseContext(), "Sharing tools have not been installed.", Toast.LENGTH_SHORT).show();
            }

        }
private void sendToContactUs() {

    sendIntent.setPackage("com.whatsapp");
    String url = "https://api.whatsapp.com/send?phone=" + phoneNo + "&text=" + "Unique Code - "+CommonUtils.getMacAddress();
    sendIntent.setDataAndType(Uri.parse(url),"text/plain");


    if(sendIntent.resolveActivity(getPackageManager()) != null){
        startActivity(sendIntent);
    }else{
        Toast.makeText(getApplicationContext(),"Please Install Whatsapp Massnger App in your Devices",Toast.LENGTH_LONG).show();
    }
}

 public void shareWhatsup(String text) {


        String smsNumber = "91+" + "9879098469"; // E164 format without '+' sign

        try {
            String url = "https://api.whatsapp.com/send?phone=" + smsNumber + "&text=" + URLEncoder.encode(text, "UTF-8");

            intent.setData(Uri.parse(url));
        } catch (Exception e) {

        }

        //    intent.setAction(Intent.ACTION_SEND);
        //   intent.setType("image/jpeg");
        //   intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUriArray);
        startActivity(intent);
