Android application fro sending e mails

Here is a step-by-step guide to creating an Android application for sending emails:

Step 1: Create a new Android project

• Open Android Studio and create a new project.
• Choose "Empty Activity" as the project template.
• Name your project, for example, "EmailSender".

Step 2: Add the necessary permissions

• In the AndroidManifest.xml file, add the following permissions:

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

  Step 3: Create a layout for the email composition screen

• Create a new layout file activity_main.xml in the res/layout directory:

  
  <?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
  
    <EditText
        android:id="@+id/subject_edit_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Subject" />
  
    <EditText
        android:id="@+id/body_edit_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Body" />
  
    <Button
        android:id="@+id/send_button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Send" />

• Create a new Java class MainActivity.java in the src/main/java directory:

  
  import android.app.Activity;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.Button;
  import android.widget.EditText;

public class MainActivity extends Activity { private EditText subjectEditText; private EditText bodyEditText; private Button sendButton;

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

    subjectEditText = findViewById(R.id.subject_edit_text);
    bodyEditText = findViewById(R.id.body_edit_text);
    sendButton = findViewById(R.id.send_button);

    sendButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            sendEmail();
        }
    });
}

private void sendEmail() {
    String subject = subjectEditText.getText().toString();
    String body = bodyEditText.getText().toString();
    String toAddress = "[email protected]"; // Replace with the recipient's email address

    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("message/rfc822");
    intent.putExtra(Intent.EXTRA_EMAIL, new String[]{toAddress});
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, body);

    try {
        startActivity(Intent.createChooser(intent, "Send Email"));
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(MainActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
    }
}

}

**Step 5: Add the necessary libraries**

* Add the following libraries to your project:
    + `android-support-v4.jar` (for compatibility with older Android versions)
    + `android-support-v7-appcompat.jar` (for compatibility with older Android versions)

**Step 6: Run the application**

* Run the application on an emulator or a physical device.
* Enter the recipient's email address, subject, and body in the email composition screen.
* Click the "Send" button to send the email.

Note: This is a basic example and may not work as expected on all devices or email clients. You may need to modify the code to suit your specific requirements. Additionally, this example uses the `Intent.ACTION_SEND` intent to send the email, which may not work if the device does not have an email client installed.
