解决方案

首先，你必须为添加3瓶 *的的库文件的文件夹的*这是低于


  1. 的activati​​on.jar

  2. additionnal.jar

  3. 的mail.jar

添加此code在你的应用程序之后。

其次，你必须在允许添加的的Andr​​oidManifest.xml 文件

 ＆LT;使用许可权的android：NAME =android.permission.INTERNET对/＆GT;

How do you send mail from Android? The same code is working fine in a Java project but not in Android.

1) GmailSender.java

       import javax.activation.DataHandler;

     GMailSender sender = new GMailSender("xxx@gmail.com", "xxxxxx");
     sender.sendMail("Test", "Test mail",  "xxx@gmail.com", "xxx@gmail.com");

GMailSender class call in activity class but I got error.

解决方案

Firstly you have to add 3 jar *files in libs folder* which are below

  1. activation.jar
  2. additionnal.jar
  3. mail.jar

After add this code in your application.

Secondly you have to add permission in AndroidManifest.xml file

<uses-permission android:name="android.permission.INTERNET"/>

MainActivity.java

package com.example.mailsenderactivity;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;

import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {

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

    final Button send = (Button) this.findViewById(R.id.send);
    send.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            try {
                GMailSender sender = new GMailSender("<U R GMAIL ADDRESS>",
                        "<GMAIL PASSWORD>");
                sender.sendMail("This is Subject", "This is Body",
                        "<U R GMAIL (SENDER)>", "<RECIPIENT(RECEIVER) EMAIL ADDRESS>");
                Toast.makeText(MainActivity.this, "Mail Send Successfully.....", Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                Log.e("SendMail", e.getMessage(), e);
            }

        }
    });
}

@Override
