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");
Intent mIntent = new Intent(Intent.ACTION_SENDTO, mUri);
mIntent.setPackage("com.whatsapp");
mIntent.putExtra("sms_body", "The text goes here");
mIntent.putExtra("chat",true);
startActivity(mIntent);

The problem is that the parameter "sms_body" is not received on WhatsApp, though the contact is selected.

Answer 1

Try using Intent.EXTRA_TEXT instead of sms_body as your extra key. Per WhatsApp's documentation, this is what you have to use.

An example from their website:

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

Their example uses Intent.ACTION_SEND instead of Intent.ACTION_SENDTO, so I'm not sure if WhatsApp even supports sending directly to a contact via the intent system. Some quick testing should let you determine that.

Answer 2

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);

Answer 3

This new method, send message to a specific contact via whatsapp in Android. For more information look here

            Intent sendIntent = new Intent();
            sendIntent.setAction(Intent.ACTION_VIEW);
            String url = "https://api.whatsapp.com/send?phone=" + number + "&text=" + path;
            sendIntent.setData(Uri.parse(url));
            activity.startActivity(sendIntent);here

Answer 4

I found the right way to do this and is just simple after you read this article: http://howdygeeks.com/send-whatsapp-message-unsaved-number-android/

phone and message are both String.

Source code:

try {

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

    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!

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. I have published this in my android app, so if you want to see it live try my app Bill Book

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!

Answer 6

you can use this code:

 Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("text/plain");
sendIntent.putExtra("jid", "9194******22" + "@s.whatsapp.net");// here 91 is country code
sendIntent.putExtra(Intent.EXTRA_TEXT, "Demo test message");
startActivity(sendIntent);

This is the best way to send Message through Whatsapp to specific number or unsaved number

private void openWhatsApp() {
    String smsNumber = "252634651588";
    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(getContext(), "WhatsApp not Installed",
                Toast.LENGTH_SHORT).show();
        startActivity(goToMarket);
    }
}

private boolean whatsappInstalledOrNot(String uri) {
    PackageManager pm = Objects.requireNonNull(getContext()).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;
}

Answer 8

This is what works for me.

The parameter 'body' gets not red by the whatsapp app, use 'Intent.EXTRA_TEXT' instead.

By setting the 'phoneNumber' you specify the contact to open in whatsapp.

Intent sendIntent = new Intent(Intent.ACTION_SENDTO, 
       Uri.parse("smsto:" + "" + phoneNumber + "?body=" + encodedMessage));
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setPackage("com.whatsapp");
startActivity(sendIntent);

Answer 9

Uri mUri = Uri.parse("smsto:+90000900000");
Intent mIntent = new Intent(Intent.ACTION_SENDTO, mUri);
mIntent.setPackage("com.whatsapp");
mIntent.putExtra("chat",true);
startActivity(Intent.createChooser(mIntent, "Share with"));

Works great to send message to specific contact on WhatsApp from my android app

We can share/send message to whats app. Below is Sample code to send text message on Whats-app

1. Single user

private void shareToOneWhatsAppUser(String message) {

    /**
     * NOTE:
     * Message is shared with only one user at a time. and to navigate back to main application user need to click back button
     */
    Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
    whatsappIntent.setType("text/plain");
    whatsappIntent.setPackage("com.whatsapp");
    whatsappIntent.putExtra(Intent.EXTRA_TEXT, message);

    //Directly send to specific mobile number...
    String smsNumber = "919900990099";//Number without with country code and without '+' prifix
    whatsappIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix

    if (whatsappIntent.resolveActivity(getPackageManager()) == null) {
        Toast.makeText(MainActivity.this, "Whatsapp not installed.", Toast.LENGTH_SHORT).show();
        return;
    }

    startActivity(whatsappIntent);
}

2. Multiple user

private void shareToMultipleWhatsAppUser(String message) {

    /**
     * NOTE:
     *
     * If want to send same message to multiple users then have to select the user to whom you want to share the message & then click send.
     * User navigate back to main Application once he/she select all desired persons and click send button.
     * No need to click Back Button!
     */

    Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
    whatsappIntent.setType("text/plain");
    whatsappIntent.setPackage("com.whatsapp");
    whatsappIntent.putExtra(Intent.EXTRA_TEXT, message);

    if (whatsappIntent.resolveActivity(getPackageManager()) == null) {
        Toast.makeText(MainActivity.this, "Whatsapp not installed.", Toast.LENGTH_SHORT).show();
        return;
    }

    startActivity(whatsappIntent);
}

One more way to achieve the same

private void shareDirecctToSingleWhatsAppUser(String message) {

    /**
     * NOTE:
     * Message is shared with only one user at a time. and to navigate back to main application user need to click back button
     */

    //Directly send to specific mobile number...
    String smsNumber = "919900000000";//Intended user`s mobile number with country code & with out '+'

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

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

Answer 11

Try this code

Uri uri = Uri.parse("smsto:" + "+6281122xxx");
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra(Intent.EXTRA_TEXT, getResources().getString(R.string.default_message_wa));
i.setPackage("com.whatsapp");
startActivity(Intent.createChooser(i, ""));

You can't put string directly on putExtra like this

i.putExtra(Intent.EXTRA_TEXT, "YOUR TEXT");

Change your code and get string from resource like this

i.putExtra(Intent.EXTRA_TEXT, getResources().getString(R.string.default_message_wa));

Answer 12

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_VIEW); 
String url ="https://wa.me/your number"; 
sendIntent.setData(Uri.parse(url));
startActivity(sendIntent);

Answer 13

Here's my way to do it:

First, you check if the person even has a WhatsApp account:

@RequiresPermission(permission.READ_CONTACTS)
public String getContactMimeTypeDataId(@NonNull Context context, String contactId, @NonNull String mimeType) {
    if (TextUtils.isEmpty(mimeType) || !PermissionUtil.hasPermissions(context, Manifest.permission.READ_CONTACTS))
        return null;
    ContentResolver cr = context.getContentResolver();
    Cursor cursor = cr.query(ContactsContract.Data.CONTENT_URI, new String[]{Data._ID}, Data.MIMETYPE + "= ? AND "
            + ContactsContract.Data.CONTACT_ID + "= ?", new String[]{mimeType, contactId}, null);
    if (cursor == null)
        return null;
    if (!cursor.moveToFirst()) {
        cursor.close();
        return null;
    }
    String result = cursor.getString(cursor.getColumnIndex(Data._ID));
    cursor.close();
    return result;
}

and if all seem well, you open it as if it's from the web:

            final String contactMimeTypeDataId = getContactMimeTypeDataId(context, contactId, "vnd.android.cursor.item/vnd.com.whatsapp.profile");
            if (contactMimeTypeDataId != null) {
                final String whatsAppPhoneNumber = PhoneNumberHelper.normalizePhone(phoneNumber);
                String url = "https://api.whatsapp.com/send?phone="+ whatsAppPhoneNumber ;
                intent = new Intent(Intent.ACTION_VIEW,Uri.parse(url));
                intent.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET | Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP)
                .setPackage("com.whatsapp");
                startActivity(intent);
            }

You can also check if WhatsApp is even installed before of all of this:

        final PackageManager packageManager = context.getPackageManager();
        final ApplicationInfo applicationInfo = packageManager.getApplicationInfo("com.whatsapp", 0);
        if (applicationInfo == null)
           return;
