Here,you will see the design page(Graphical user Interface).



Now,you will see the activity_main.xml code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="xyz.rvconstructions.www.sendemailapp.MainActivity">
    <EditText android:layout_width="wrap_content" android:layout_height="wrap_content" android:inputType="textEmailAddress" android:ems="10" android:id="@+id/editText" android:layout_alignParentTop="true" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" />
    <EditText android:layout_width="wrap_content" android:layout_height="wrap_content" android:inputType="textEmailAddress" android:ems="10" android:id="@+id/editText2" android:layout_below="@+id/editText" android:layout_alignRight="@+id/editText" android:layout_alignEnd="@+id/editText" />
    <EditText android:layout_width="wrap_content" android:layout_height="wrap_content" android:inputType="textEmailAddress" android:ems="10" android:id="@+id/editText3" android:layout_below="@+id/editText2" android:layout_alignRight="@+id/editText2" android:layout_alignEnd="@+id/editText2" />
    <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="SEND MAIL" android:id="@+id/sendbttn" android:layout_centerVertical="true" android:layout_alignLeft="@+id/editText3" android:layout_alignStart="@+id/editText3" />
    <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Recipient" android:id="@+id/textView" android:layout_alignBottom="@+id/editText" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
    <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="subject" android:id="@+id/textView2" android:layout_alignBottom="@+id/editText2" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
    <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Message Body" android:id="@+id/textView3" android:layout_alignBottom="@+id/editText3" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" /> </RelativeLayout>

Step 5

Now ,you will build on AndroidManifest.xml code.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="xyz.rvconstructions.www.sendemailapp">
    <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" /> </intent-filter>
        </activity>
    </application>
</manifest>

Step 6

Now, you will go to MainActivity.java page and you will build the java code.

First of all you will declare the Header file.

package xyz.rvconstructions.www.sendemailapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.net.Uri;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

Now, you will declare and get the reference in the button and perform the OnClickListener.

Button startBtn = (Button) findViewById(R.id.sendbttn);
startBtn.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
        sendEmail();
    }
});

Here, you will assign the method() of sendEmail().

protected void sendEmail() {
        Log.i("Send email", "");
        String[] TO = {
            "[email protected]"
        };
        String[] CC = {
            "[email protected]"
        };
        Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent.setData(Uri.parse("mailto:"));
        emailIntent.setType("text/plain");
        emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
        emailIntent.putExtra(Intent.EXTRA_CC, CC);
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Your subject");
        emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message goes here");
        try {
            startActivity(Intent.createChooser(emailIntent, "Send mail..."));
            finish();
            Log.i("Finished sending email...", "");
        } catch (android.content.ActivityNotFoundException ex) {
            Toast.makeText(MainActivity.this, "There is no email client installed.", Toast.LENGTH_SHORT).show();
        }
    }
    // This is just a sample script. Paste your real code (javascript or HTML) here.
if ('this_is' == /an_example/) {
    of_beautifier();
} else {
    var a = b ? (c % d) : e[f];
}

Step 7

Now ,you will run the application in emulator or devices.



Here,you will choose the emulator or devices



Step 8

Now, you will see the output.



Here, you will fill the data and you will click the SEND EMAIL button.



Now, you will choose one option  --  Gmail.com(Email).
