}
}
3.使用工具包：
but_emailtest.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//使用HandlerThread
mhandlerthread=new HandlerThread("myhandlerthread");
mhandlerthread.start();
mhandler = new Handler(mhandlerthread.getLooper());
mhandler.post(mRunnable);
}
});
}
Runnable mRunnable = new Runnable() {
@Override
public void run() {
NetworkUtils nu=new NetworkUtils();
EmailUtils email=new EmailUtils();
//emsuper.run();ail.sendToFileEmail("哈哈哈test","这是荣哦支持你下哈哈",MinShiLi.this);
String to="fajianren@17xu.com";
String host = "smtp.17xu.com";
String address = "88888@17xu.com"; //发件人地址
String from = "88888@17xu.com";
String password = "******";// 密码
String filepath=nu.getSDPath()+"/"+"qq.png";
String port = "25"; //发邮件端口号
try {
//email.SendEmail(host, address, from, password, to, port, "主题测试", "内容哦哈哈哈哈哈哈哈");
//附件
email.SendEmailfile(host, address, from, password, to, port, "主题测试", "内容哦哈哈哈哈哈哈哈",filepath);
} catch (Exception e) {
e.printStackTrace();
}
}
};
4.sd卡获取文件路径、判断网络是否链接
package com.kllayhello.utils;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Environment;
import java.io.File;
/**
* Created by Administrator on 2016/6/30.
*/
public class NetworkUtils {
/**
* 判断网络是否链接
* */
public boolean isNetworkConnected(Context context) {
if (context != null) {
ConnectivityManager mConnectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();
if (mNetworkInfo != null) {
return mNetworkInfo.isAvailable();
}
}
return false;
}
/**
* 判断sd卡是否存在 并获取路径
* */
public String getSDPath(){
File sdDir = null;
boolean sdCardExist = Environment.getExternalStorageState()
.equals(android.os.Environment.MEDIA_MOUNTED);//判断sd卡是否存在
if(sdCardExist)
{
sdDir = Environment.getExternalStorageDirectory();//获取跟目录
}
return sdDir.toString();
}
}
