Unable to send a WhatsApp message programatically

I'm trying to send WhatsApp messages programatically using the following code.

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

This helper function is successfully called everytime (I checked by logging them), but fails to send a message. Apparently it's all going wrong at startActivity (from the logs). Posting the Log for reference.

10-20 15:59:34.029: W/System.err(16336): android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

Try the below code

try {

        Intent intent= new Intent(Intent.ACTION_SEND);
        intent.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
        intent.setPackage("com.whatsapp");

            intent.putExtra(Intent.EXTRA_TEXT, text);
            startActivity(Intent.createChooser(intent, "Share with"));

   } catch (NameNotFoundException e) {
        Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
                .show();
   }
