import android.os.Bundle;
import android.view.View;
import android.widget.Toast;


public class AutomaticEmailActivity extends Activity {

    private Mail m;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        m = new Mail("GMAIL@gmail.com", "PASS");
    }


    public void sendEmail(View view) {
        String[] toArr = { "GMAIL@gmail.com", "EMAIL@yahoo.com", "GMAIL@gmail.com" }; // This is an array, you can add more emails, just separate them with a coma
        m.setTo(toArr); // load array to setTo function
        m.setFrom("GMAIL@gmail.com"); // who is sending the email
        m.setSubject("subject");
        m.setBody("your message goes here");

        try {
             m.addAttachment("/sdcard/myPicture.jpg"); // path to file you want to attach
            if (m.send()) {
                // success
                Toast.makeText(AutomaticEmailActivity.this, "Email was sent successfully.", Toast.LENGTH_LONG).show();
            } else {
                // failure
                Toast.makeText(AutomaticEmailActivity.this, "Email was not sent.", Toast.LENGTH_LONG).show();
            }
        }
        catch (Exception e) {
