super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

buttonSend = (Button)findViewById(R.id.buttonSend);

textTo = (EditText)findViewById(R.id.editTextTo);

textSubject = (EditText)findViewById(R.id.editTextSubject);

buttonSend.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

String to = textTo.getText().toString();

String subject = textSubject.getText().toString();

Intent email = new Intent(Intent.ACTION_SEND);

email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});

email.putExtra(Intent.EXTRA_SUBJECT, subject);

email.setType("text/rfc822");

startActivity(Intent.createChooser(email, "Choose Your Account Type"));

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.activity_main, menu);
