Sending message through WhatsApp

Since I found some older posts, that tell that whatsapp doesn't support this, I was wondering if something had changed and if there is a way to open a whatsapp 'chat' with a number that I'm sending through an intent?

Sending to WhatsApp Number that exist in your contact list. Notice that we are using ACTION_SEND

 Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
 whatsappIntent.setType("text/plain");
 whatsappIntent.setPackage("com.whatsapp");
 whatsappIntent.putExtra(Intent.EXTRA_TEXT, "SMS TEXT, TEXT THAT YOU NEED TO SEND");
 try {
   startActivityForResult(whatsappIntent, 100);
 } catch (Exception e) {
   Toast.makeText(YourActivity.this, "App is not installed", Toast.LENGTH_SHORT).show();
 }

If Number doesn't exist in contact list. Use WhatsApp API.

 String number = number_phone.getText().toString(); // I toke it from Dialog box
 number = number.substring(1); // To remove 0 at the begging of number (Optional) but needed in my case
 number = "962" + number; // Replace it with your country code
 String url = "https://api.whatsapp.com/send?phone=" + number + "&text=" + Uri.parse("Text that you want to send to the current user");
 Intent whatsappIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
 whatsappIntent.setPackage("com.whatsapp");
 whatsappIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
 try {
   context.startActivity(whatsappIntent);
 } catch (android.content.ActivityNotFoundException ex) {
   Toast.makeText(YourActivity.this, "App is not installed", Toast.LENGTH_SHORT).show();
 }

Here is the latest way to send a message via Whatsapp, even if the receiver's phone number is not in your Whatsapp chat or phone's Contacts list.

private fun openWhatsApp(number: String) {
    try {
        packageManager.getPackageInfo("com.whatsapp", PackageManager.GET_ACTIVITIES)
        val intent = Intent(
            Intent.ACTION_VIEW,
            Uri.parse("https://wa.me/$number?text=I'm%20interested%20in%20your%20car%20for%20sale")
        )
        intent.setPackage("com.whatsapp")
        startActivity(intent)
    } catch (e: PackageManager.NameNotFoundException) {
        Toast.makeText(
            this,
            "Whatsapp app not installed in your phone",
            Toast.LENGTH_SHORT
        ).show()
        e.printStackTrace()
    }
}

intent.setPackage("com.whatsapp") will help you to avoid Open With chooser and open Whatsapp directly.

Importent Note: If You are ending in catch statement, even if Whatsapp is installed. Please add queries to manifest.xml as follows:

<queries>
   <package android:name="com.whatsapp" />
</queries>

Please see this answer for more details.

UPDATE Please refer to https://faq.whatsapp.com/en/android/26000030/?category=5245251

WhatsApp's Click to Chat feature allows you to begin a chat with someone without having their phone number saved in your phone's address book. As long as you know this person’s phone number, you can create a link that will allow you to start a chat with them.

Use: https://wa.me/15551234567

Don't use: https://wa.me/+001-(555)1234567

Example: https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale

Original answer Here is the solution

public void onClickWhatsApp(View view) {
    
    PackageManager pm=getPackageManager();
    try {

        Intent waIntent = new Intent(Intent.ACTION_SEND);
        waIntent.setType("text/plain");
        String text = "YOUR TEXT HERE";

        PackageInfo info=pm.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA);
        //Check if package exists or not. If not then code 
        //in catch block will be called
        waIntent.setPackage("com.whatsapp");

        waIntent.putExtra(Intent.EXTRA_TEXT, text);
        startActivity(Intent.createChooser(waIntent, "Share with"));
        
   } catch (NameNotFoundException e) {
        Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
                .show();
   }  

}

This one worked finally for me in Kotlin:

private fun navigateToWhatsApp() {
        try {
            val url = "https://api.whatsapp.com/send?phone=+91${getString(R.string.contact)}"
            startActivity(Intent(Intent.ACTION_VIEW, Uri.parse(url)).setPackage("com.whatsapp"))
        } catch (e: Exception) {
            showToast("Whatsapp app not installed in your device")
        }
    }

To check if WhatsApp is installed in device and initiate "click to chat" in WhatsApp:

Kotlin:

try {
    // Check if whatsapp is installed
    context?.packageManager?.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA)
    val intent = Intent(Intent.ACTION_VIEW, Uri.parse("https://wa.me/$internationalPhoneNumber"))
    startActivity(intent)
} catch (e: NameNotFoundException) {
    Toast.makeText(context, "WhatsApp not Installed", Toast.LENGTH_SHORT).show()
}

Java:

try {
    // Check if whatsapp is installed
    getPackageManager().getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA);
    Intent intent = Intent(Intent.ACTION_VIEW, Uri.parse("https://wa.me/" + internationalPhoneNumber));
    startActivity(intent);
} catch (NameNotFoundException e) {
    Toast.makeText(context, "WhatsApp not Installed", Toast.LENGTH_SHORT).show();
}

getPackageInfo() throws NameNotFoundException if WhatsApp is not installed.

The internationalPhoneNumber variable is used to access the phone number.

This should work whether Whatsapp is installed or not.

boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp");
if (isWhatsappInstalled) {
    Uri uri = Uri.parse("smsto:" + "98*********7")
    Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "Hai Good Morning");
    sendIntent.setPackage("com.whatsapp");
    startActivity(sendIntent);
} else {
    Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT).show();
    Uri uri = Uri.parse("market://details?id=com.whatsapp");
    Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
    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;
}

You'll want to use a URL in the following format...

https://api.whatsapp.com/send?text=text

Then you can have it send whatever text you'd like. You also have the option to specify a phone number...

https://api.whatsapp.com/send?text=text&phone=1234

What you CANNOT DO is use the following:

https://wa.me/send?text=text

You will get...

We couldn't find the page you were looking for

wa.me, though, will work if you supply both a phone number and text. But, for the most part, if you're trying to make a sharing link, you really don't want to indicate the phone number, because you want the user to select someone. In that event, if you don't supply the number and use wa.me as URL, all of your sharing links will fail. Please use app.whatsapp.com.

Use direct URL of whatsapp

String url = "https://api.whatsapp.com/send?phone="+number;
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

Simple solution, try this.

String phoneNumberWithCountryCode = "+62820000000";
String message = "Hallo";

startActivity(
    new Intent(Intent.ACTION_VIEW,
        Uri.parse(
            String.format("https://api.whatsapp.com/send?phone=%s&text=%s", phoneNumberWithCountryCode, message)
        )
    )
);

From the documentation

To create your own link with a pre-filled message that will automatically appear in the text field of a chat, use https://wa.me/whatsappphonenumber/?text=urlencodedtext where whatsappphonenumber is a full phone number in international format and URL-encodedtext is the URL-encoded pre-filled message.

Example:https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale

Code example

val phoneNumber = "13492838472"
    val text = "Hey, you know... I love StackOverflow :)"
    val uri = Uri.parse("https://wa.me/$phoneNumber/?text=$text")
    val sendIntent = Intent(Intent.ACTION_VIEW, uri)
    startActivity(sendIntent)

private fun sendWhatsappMessage(phoneNumber:String, text:String) {        
  val url = if (Intent().setPackage("com.whatsapp").resolveActivity(packageManager) != null) {
        "whatsapp://send?text=Hello&phone=$phoneNumber"
    } else {
        "https://api.whatsapp.com/send?phone=$phoneNumber&text=$text"
    }

    val browserIntent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
    startActivity(browserIntent)
}

This is a much easier way to achieve this. This code checks if whatsapp is installed on the device. If it is installed, it bypasses the system picker and goes to the contact on whatsapp and prefields the text in the chat. If not installed it opens whatsapp link on your web browser.

Tested on Marshmallow S5 and it works!

    Uri uri = Uri.parse("smsto:" + "phone number with country code");
    Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri);
    sendIntent.setPackage("com.whatsapp");
    startActivity(sendIntent);

This will open a direct chat with a person, if whatsapp not installed this will throw exception, if phone number not known to whatsapp they will offer to send invite via sms or simple sms message

        Intent sendIntent = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(sendIntent);

The following API can be used in c++ as shown in my article.

You need to define several constants:

//
#define    GroupAdmin                <YOUR GROUP ADMIN MOBILE PHONE>
#define GroupName                <YOUR GROUP NAME>
#define CLIENT_ID                <YOUR CLIENT ID>
#define CLIENT_SECRET            <YOUR CLIENT SECRET>

#define GROUP_API_SERVER        L"api.whatsmate.net"
#define GROUP_API_PATH          L"/v3/whatsapp/group/text/message/12"
#define IMAGE_SINGLE_API_URL    L"http://api.whatsmate.net/v3/whatsapp/group/image/message/12"

//

Then you connect to the API’s endpoint.

hOpenHandle = InternetOpen(_T("HTTP"), INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);
if (hOpenHandle == NULL)
{
    return false;
}

hConnectHandle = InternetConnect(hOpenHandle,
    GROUP_API_SERVER,
    INTERNET_DEFAULT_HTTP_PORT,
    NULL, NULL, INTERNET_SERVICE_HTTP,
    0, 1);

if (hConnectHandle == NULL)
{
    InternetCloseHandle(hOpenHandle);
    return false;
}

Then send both header and body and wait for the result that needs to be “OK”.

Step 1 - open an HTTP request:

const wchar_t *AcceptTypes[] = { _T("application/json"),NULL };
HINTERNET hRequest = HttpOpenRequest(hConnectHandle, _T("POST"), GROUP_API_PATH, NULL, NULL, AcceptTypes, 0, 0);

if (hRequest == NULL)
{
    InternetCloseHandle(hConnectHandle);
    InternetCloseHandle(hOpenHandle);
    return false;
}

Step 2 - send the header:

std::wstring HeaderData;

HeaderData += _T("X-WM-CLIENT-ID: ");
HeaderData += _T(CLIENT_ID);
HeaderData += _T("\r\nX-WM-CLIENT-SECRET: ");
HeaderData += _T(CLIENT_SECRET);
HeaderData += _T("\r\n");
HttpAddRequestHeaders(hRequest, HeaderData.c_str(), HeaderData.size(), NULL);

Step 3 - send the message:

std::wstring WJsonData;
WJsonData += _T("{");
WJsonData += _T("\"group_admin\":\"");
WJsonData += groupAdmin;
WJsonData += _T("\",");
WJsonData += _T("\"group_name\":\"");
WJsonData += groupName;
WJsonData += _T("\",");
WJsonData += _T("\"message\":\"");
WJsonData += message;
WJsonData += _T("\"");
WJsonData += _T("}");

const std::string JsonData(WJsonData.begin(), WJsonData.end());

bResults = HttpSendRequest(hRequest, NULL, 0, (LPVOID)(JsonData.c_str()), JsonData.size());

Now just check the result:

TCHAR StatusText[BUFFER_LENGTH] = { 0 };
DWORD StatusTextLen = BUFFER_LENGTH;
HttpQueryInfo(hRequest, HTTP_QUERY_STATUS_TEXT, &StatusText, &StatusTextLen, NULL);
bResults = (StatusTextLen && wcscmp(StatusText, L"OK")==FALSE);

As the documentation says you can just use an URL like:

https://wa.me/15551234567

Where the last segment is the number in in E164 Format

Uri uri = Uri.parse("https://wa.me/15551234567");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

get the contact number whom you want to send the message and create uri for whatsapp, here c is a Cursor returning the selected contact.

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);

Currently, the only official API that you may make a GET request to:

https://api.whatsapp.com/send?phone=919773207706&text=Hello

Anyways, there is a secret API program already being ran by WhatsApp

I'm really late here but I believe that nowadays we have shorter and better solutions to send messages through WhatsApp.

You can use the following to call the system picker, then choose which app you will use to share whatever you want.

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);

If you are really need to send through WhatsApp all you need to do is the following (You will skip the system picker)

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

If you need more information you can find it here: WhatsApp FAQ

The following code is used by Google Now App and will NOT work for any other application.

I'm writing this post because it makes me angry, that WhatsApp does not allow any other developers to send messages directly except for Google.

And I want other freelance-developers to know, that this kind of cooperation is going on, while Google keeps talking about "open for anybody" and WhatsApp says they don't want to provide any access to developers.

Recently WhatsApp has added an Intent specially for Google Now, which should look like following:

Intent intent = new Intent("com.google.android.voicesearch.SEND_MESSAGE_TO_CONTACTS");
intent.setPackage("com.whatsapp");
intent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.VoiceMessagingActivity"));

intent.putExtra("com.google.android.voicesearch.extra.RECIPIENT_CONTACT_CHAT_ID", number);
intent.putExtra("android.intent.extra.TEXT", text);
intent.putExtra("search_action_token", ?????);

I could also find out that "search_action_token" is a PendingIntent that contains an IBinder-Object, which is sent back to Google App and checked, if it was created by Google Now.

Otherwise WhatsApp will not accept the message.

            intent.setType("text/plain");
            intent.putExtra(Intent.EXTRA_TEXT, element);

} catch (NameNotFoundException e) {
    ToastHelper.MakeShortText("Whatsapp have not been installed.");

With this code you can open the whatsapp chat with the given number.

void openWhatsappContact(String number) {
    Uri uri = Uri.parse("smsto:" + number);
    Intent i = new Intent(Intent.ACTION_SENDTO, uri);
    i.setPackage("com.whatsapp");  
    startActivity(Intent.createChooser(i, ""));

I found the following solution, first you'll need the whatsapp id:

Matching with reports from some other threads here and in other forums the login name I found was some sort of: international area code without the 0's or + in the beginning + phone number without the first 0 + @s.whatsapp.net

For example if you live in the Netherlands and having the phone number 0612325032 it would be [email protected] -> +31 for the Netherlands without the 0's or + and the phone number without the 0.

public void sendWhatsAppMessageTo(String whatsappid) {

Cursor c = getSherlockActivity().getContentResolver().query(ContactsContract.Data.CONTENT_URI,
        new String[] { ContactsContract.Contacts.Data._ID }, ContactsContract.Data.DATA1 + "=?",
        new String[] { whatsappid }, null);
c.moveToFirst();

Intent whatsapp = new Intent(Intent.ACTION_VIEW, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
c.close();

 if (whatsapp != null) {

startActivity(whatsapp);      

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

}

Check this code,

    public void share(String subject,String text) {
     final Intent intent = new Intent(Intent.ACTION_SEND);

String score=1000;
     intent.setType("text/plain");
     intent.putExtra(Intent.EXTRA_SUBJECT, score);
     intent.putExtra(Intent.EXTRA_TEXT, text);

     startActivity(Intent.createChooser(intent, getString(R.string.share)));
}
