In this blog. we will learn about sending a message from your application to a WhatsApp Number and how you can open a particular contact in WhatsApp.
While building applications many times we need to provide the user with a facility of contacting the service providers and WhatsApp messaging in today’s World is much more popular.
Opening a particular contact or sending some particular text/url/ images to WhatsApp is a task but combining them both and that too with not so much clear documentation is a hurdle that needs to be overcome. And After Following this blog, you will see that reading the documentation is hard than implementing the same.
First, let’s have a look at the code snippet to send a particular message from your application to WhatsApp Application. As per the official documents and my implementation of the docs you can directly use the below-shared Code Segment for the aforesaid purpose.
CODE :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
public void openWhatsApp(View view){ PackageManager pm=getPackageManager(); try { Intent waIntent = new Intent(Intent.ACTION_SEND); waIntent.setType("text/plain"); String text = "This is a Test"; // Replace with your own message. 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 (PackageManager.NameNotFoundException e) { Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT) .show(); }catch(Exception e){ e.printStacktrace(); } } |
Now, let’s have a look at how we can open a particular WhatsApp Number on the WhatsApp application.
CODE :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
public void openWhatsApp(View view){ PackageManager pm=getPackageManager(); try { String toNumber = "xxxxxxxxxx"; // 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 sendIntent = new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:" + "" + toNumber /*+ "?body=" + "")); sendIntent.setPackage("com.whatsapp"); startActivity(sendIntent); } catch (Exception e){ e.printStackTrace(); Toast.makeText(MainActivity.this,"it may be you dont have whats app",Toast.LENGTH_LONG).show(); } } |
But if you want to send a particular message to a particular user from your application to WhatsApp. All you need to do is to implement this segment of code and everything will work fine.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
public void openWhatsApp(View view){ try { String text = "This is a test";// Replace with your message. String toNumber = "xxxxxxxxxx"; // 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)); startActivity(intent); } catch (Exception e){ e.printStackTrace(); } } |
I prefer using the last piece of code as it will automatically check if WhatsApp is installed or not and if WhatsApp is not installed, this will redirect to the Google play store for installing WhatsApp.
That’s All. Keep coding and Keep Sharing.
We have also developed many WhatsApp integrations for e-commerce platforms including Magento 2 WhatsApp Extension, which allows customers to contact the store admin from the social app.
