Email Intent Examples

A step by step Email Intent example.

Android Email Intent Demo

A short demo that illustrates how to send an email as an Intent within an android mobile application.

Let us look at a full android Email Intent sample project.

Step 1. Our Android Manifest

We will need to look at our AndroidManifest.xml.

(a). AndroidManifest.xml

Our AndroidManifest file.

Here we will add the following permission:

  1. Our INTERNET permission.
  2. Our SEND_SMS permission.
  3. Our READ_EXTERNAL_STORAGE permission.
  4. Our WRITE_EXTERNAL_STORAGE permission.

Here is the full Android Manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.jasonbutwell.emailintentdemo">

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.SEND_SMS"/>

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <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 2. Design Layouts

Let's create the following layouts:

(a). activity_main.xml

Our activity_main layout.

Inside your /res/layout/ directory create an xml layout file named activity_main.xml and add the following 4 UI widgets and ViewGroups:

  1. RelativeLayout
  2. EditText
  3. TextView
  4. Button
<?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:id="@+id/activity_main"
    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"
    android:background="@drawable/my_custom_background"
    tools:context="com.jasonbutwell.emailintentdemo.MainActivity">

    <EditText
        android:background="@drawable/back"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textPersonName"
        android:text=""
        android:hint="@string/enter_your_name"
        android:ems="10"
        android:layout_below="@+id/emailTitleID"

        android:lines="1"
        android:textSize="14sp" />

    <EditText

        android:text=""
        android:hint="@string/enter_your_subject"
        android:ems="10"
        android:layout_marginTop="18dp"
        android:id="@+id/subject"
        android:lines="1"
        android:layout_below="@+id/PhoneNo"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:textSize="14sp" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/send_us_an_email"

        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"

        android:text=""
        android:hint="@string/enter_your_message_here"
        android:ems="10"
        android:id="@+id/Message"
        android:lines="6"
        android:minLines="6"
        android:maxLines="10"
        android:scrollbars="vertical"
        android:textSize="14sp"
        android:layout_marginTop="24dp"
        android:layout_below="@+id/subject"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

    <Button
        android:background="@drawable/button_shape"
        android:text="@string/send"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="34dp"
        android:id="@+id/sendButton"
        android:textColor="@android:color/white"
        android:textSize="16sp"
        android:onClick="sendEmail"
        android:layout_below="@+id/Message"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

    <Button

        android:onClick="sendText"
        android:layout_alignBaseline="@+id/sendButton"
        android:layout_alignBottom="@+id/sendButton"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />

    <Button
        android:background="@drawable/button_shape"
        android:text="@string/open_web_page"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/sendButton3"
        android:textColor="@android:color/white"
        android:textSize="16sp"
        android:onClick="openWebPage"

        android:layout_alignBottom="@+id/sendButton2"
        android:layout_centerHorizontal="true" />

    <Button
        android:text="Button"

        android:layout_height="wrap_content"
        android:layout_below="@+id/sendButton3"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="48dp"
        android:id="@+id/openGalleryButton"
        android:onClick="openGallery" />
</RelativeLayout>

Step 3. Write Code

Finally we need to write our code as follows:

(a). MainActivity.java

Our MainActivity class.

Create a java file named MainActivity.java.

Then create a class that extends AppCompatActivity and add its contents as follows:

We will add imports from android SDK and other packages. Here are some of the imports we will use in this class:

  1. Intent from the android.content package.
  2. Cursor from the android.database package.
  3. Uri from the android.net package.
  4. Bundle from the android.os package.
  5. MediaStore from the android.provider package.
  6. AppCompatActivity from the android.support.v7.app package.
  7. Log from the android.util package.
  8. View from the android.view package.
  9. EditText from the android.widget package.
  10. Toast from the android.widget package.

We will be overriding the following methods:

  1. onCreate(Bundl).
  2. onActivityResult(int).

We will be creating the following methods:

  1. openGallery(View view).
  2. openWebPage(View view).
  3. sendText(View view ).
  4. sendEmail(View view).

Here is the full java code for this class:

package replace_with_your_package_name;

import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

import java.io.File;

public class MainActivity extends AppCompatActivity {

    int REQUEST_CODE_LOAD_IMAGE = 101;
    String picturePath;
    Uri imagepath;

    private EditText name, phone, subject, message;

    Intent smsIntent, emailIntent, chooserIntent = null;

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

        name = (EditText)findViewById(R.id.Name);
        phone = (EditText)findViewById(R.id.PhoneNo);
        subject = (EditText)findViewById(R.id.subject);
        message = (EditText)findViewById(R.id.Message);
    }

    public void openGallery(View view) {

        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        intent.putExtra("return-data",true);
        startActivityForResult(Intent.createChooser(intent,"Compete Action Using"),REQUEST_CODE_LOAD_IMAGE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == REQUEST_CODE_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {

            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            picturePath = cursor.getString(columnIndex);
            cursor.close();

            imagepath = selectedImage;

            Log.i("file",selectedImage.toString());

        }
    }

    public void openWebPage(View view) {
        String url="http://www.google.com";

        Intent webIntent = new Intent(Intent.ACTION_VIEW);
        webIntent.setData(Uri.parse(url));
        startActivity(webIntent);
    }

    public void sendText( View view ) {
        smsIntent = new Intent(Intent.ACTION_VIEW);

        String bodyTextSMS = "SMS From: " + name.getText().toString() + ", Phone number: " + phone.getText().toString() + "\n\n"+ message.getText().toString();

        smsIntent.putExtra("sms_body",bodyTextSMS);
        smsIntent.setType("vnd.android-dir/mms-sms");
        smsIntent.setData(Uri.parse("sms:07475653985"));

        startActivity(smsIntent);
    }

    public void sendEmail(View view) {

        boolean successful = true;

        if ( name.length() < 1 || phone.length() < 1 || subject.length() < 1 || message.length() < 1 )
            successful = false;

        if ( !successful )
            Toast.makeText(getApplicationContext(),"Please fill out all required fields",Toast.LENGTH_LONG).show();
        else {
            emailIntent = new Intent(Intent.ACTION_SEND);
            emailIntent.setData(Uri.parse("mailto:"));

            String[] to = {"[email protected]"};

            emailIntent.putExtra(Intent.EXTRA_EMAIL, to);
            emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject.getText().toString());

            String bodyTextEmail = "Email from: " + name.getText().toString() + ", Phone number: " + phone.getText().toString() + "\n\n"+ message.getText().toString();

            emailIntent.putExtra(Intent.EXTRA_TEXT, bodyTextEmail);
            emailIntent.setType("message/rfc822");

            if ( imagepath != null ) {
                File file = new File(this.getFilesDir().getAbsolutePath()+picturePath);
                emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                emailIntent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
                emailIntent.setType("image/jpeg");
                emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+file.getAbsolutePath())); //Your image file
            }

            chooserIntent = Intent.createChooser(emailIntent, "Send Email");
            startActivity(chooserIntent);
        }
    }

}
