问题
I tried to share a multi-line text using the following code, but only the last line appears.
val sharingIntent = Intent(Intent.ACTION_SEND)
sharingIntent.setType("text/plain")
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Found this cool deal! Check it out.")
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, TITLE)
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "MRP : $PRICE")
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Deal Price : $DEAL_PRICE")
startActivity(Intent.createChooser(sharingIntent, "Share using"))

When you call putExtra(key, value), any value previous put under the same key gets wiped out. Try putting a single string that contains all the text you want:
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT,
"Found this cool deal! Check it out.\n" +
TITLE + "\n" +
"MRP : $PRICE\n" +
"DEAL PRICE : $DEAL_PRICE");
As for the HTML content, you'll need to show us the code you used. However, you probably don't want to use fromHtml(); that converts HTML to styled text, which I suspect is not what WhatsApp expects to receive. Try just sending the raw HTML with the correct MIME type.

The reason that only the last line appears is that a single intent can only have one value for a key. So each time you call putExtra(EXTRA_TEXT,foo), you're overwriting the previous one. If you want to send multiple lines, send it as a single string with '\n' characters.
As for sending html- you'd need to tell it that you're sending html. You're telling it you're sending plain text. Change the mime type to text/html if you're sending html. (Note: I have no idea if whatsapp supports html or not, but that's the way you'd send html to any app that does support it).

In Kotlin you can use tripple quote martks for multilined text, I'm not sure if you can in Java.
val moreStuff = "Text or Numbers or arrays"
var myText = """
line 1 of the text
line 2 of the text
$moreStuff
"""
It will format it the way you type it
var myText = """
Found this cool deal! Check it out.
$TITLE
MRP : $PRICE
DEAL PRICE : $DEAL_PRICE)"""
