problem with sending email ... goes back to previous activity

I have 2 activities- A and B. I have a list on activity A and if I click on it, it goes to activity B开发者_如何学运维. On activity B, I have a button for sharing email with the following code :

shareEmail = (Button) findViewById(R.id.emailButton);

    shareEmail.setOnClickListener(new View.OnClickListener() 
    {
        public void onClick(View v)
        {
            System.out.println("!!! email !!!");


         Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
             emailIntent.setType("text/html");


         emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "sharing something interesting" );
         emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "sharing something interesting !!" );

         //hideKeyboard();

         activityB.this.startActivity(emailIntent);


        }
    });

Now, when I send an email, the email window closes and activity B also closes. I am not sure why that is happening. Any hints ? Thanks.

you have to use intent.crateChoose in start activity. now use the edited code.

shareEmail = (Button) findViewById(R.id.emailButton);

    shareEmail.setOnClickListener(new View.OnClickListener() 
    {
        public void onClick(View v)
        {
            System.out.println("!!! email !!!");


         Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
             emailIntent.setType("text/html");


         emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "sharing something interesting" );
         emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "sharing something interesting !!" );

         //hideKeyboard();

         activityB.this.startActivity(Intent.createChooser(emailIntent,"Sending Mail..."));


        }
    });
