Android 发送邮件信息,附带附件

直接上demo代码:

import android.os.Environment;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

    private Button mButton;

    private String to = "wardenr_sprites@foxmail.com,5448100202@qq.com";
    private String subject = "Application Exception for app developer";
    private String text = "<table align=center width=100%><tr><td align=right>邮件测试mail test</td></tr></table>";

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

        mButton = (Button) findViewById(R.id.button1);
        mButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                new Thread(new Runnable() {

                    @Override
                    public void run() {
                        // TODO Auto-generated method stub
                        int i = EmailSender.send(to, subject, "user return exception information to developer, please find the attached file !");
                        System.out.println("i = " + i);
                    }

                }).start();

                // sendEmail();
            }

        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

核心类:EmailSender.java

package mail;

/**
* int i = EmailSender.send(to, subject, "user return exception information to developer, please find the attached file !");
* 其中第一个参数to是发送给对方的邮箱地址,比如发送给270791800@qq.com,如果是多个邮箱,邮箱地址之间用","(英文逗号隔开)
* 其中第二个参数subject是发给对方邮箱看到的邮件的title,
* 其中第三个参数是邮箱的正文
