    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.code2care.example.whatsappintegrationexample.MainActivity"

    android:layout_centerHorizontal="true"
    android:onClick="sendMessae"
    android:layout_marginBottom="21dp"
    android:text="Send to WhatsApp" />

    android:id="@+id/editText1"
    android:layout_width="fill_parent"

MainActivity.java



package com.code2care.example.whatsappintegrationexample;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.EditText;

public class MainActivity extends ActionBarActivity {

	private EditText message;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		message = (EditText) findViewById(R.id.message);

	}

	public void sendMessage(View v) {

		String whatsAppMessage = message.getText().toString();

		Intent sendIntent = new Intent();
		sendIntent.setAction(Intent.ACTION_SEND);
		sendIntent.putExtra(Intent.EXTRA_TEXT, whatsAppMessage);
		sendIntent.setType("text/plain");

		// Do not forget to add this to open whatsApp App specifically
		sendIntent.setPackage("com.whatsapp");
