发邮件

发送邮件使用android.content.Intent.ACTION_SEND,参数来实现通过手机发Email服务。收发Email的过程是通过android内置的Gmail程序，而非直接使用smtp的protocol，而模拟器上并未内置Gmail Client，因此该程序只能在真机上运行。
其实android中发送email有很多写法：
1.

Uri uri = Uri.parse("mailto:****@gmail.com");Intent emailIntent = new Intent(Intent.ACTION_SEND,uri);startActivity(emailIntent);

2. 如下面代码所示：

package com.kevin.email;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;public class Main extends Activity {private Button btn_send;private EditText et_receiver,et_cc,et_subject,et_body;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        et_receiver = (EditText) findViewById(R.id.et_receiver);        et_cc = (EditText) findViewById(R.id.et_attached);        et_subject = (EditText) findViewById(R.id.et_subject);        et_body = (EditText) findViewById(R.id.et_body);        btn_send = (Button) findViewById(R.id.btn_send);        btn_send.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// 通过Intent发送邮件Intent emailIntent = new Intent("android.content.Intent.ACTION_SEND");// 设置邮件格式emailIntent.setType("plain/text");// 取得收件人地址，抄送，主题，正文String[] receiver = new String[]{et_receiver.getText().toString()};String[] cc = new String[]{et_cc.getText().toString()};// 邮件信息String subject = et_subject.getText().toString();String body = et_body.getText().toString();emailIntent.putExtra("android.content.Intent.EXTRA_EMAIL", receiver);emailIntent.putExtra("android.content.Intent.EXTRA_CC", cc);emailIntent.putExtra("android.content.Intent.EXTRA_SUBJECT", subject);emailIntent.putExtra("android.content.Intent.EXTRA_TEXT", body);// 打开gmail并将相关参数传入startActivity(Intent.createChooser(emailIntent, getString(R.string.send)));}});    }}

上例中只是发送文字，如果你想发送有文件的email，代码如下：

Intent intent = new Intent(Intent.ACTION_SEND);intent.putExtra(Intent.EXTRA_STREAM,"file:///sdcard/music.mp3");intent.setType("audio/mp3");startActivity(Intent.createChooser(intent,"发送中..."));
