我們沒必要建立一個全局的，本文選擇第二種方案，創(chuàng)建一個當(dāng)前應(yīng)用私有的獨(dú)立進(jìn)程。
3.通知用戶和點(diǎn)擊查看
public class messageservice extends service {

//獲取消息線程

//通知欄消息
private int messagenotificationid = 1000;

private notificationmanager messagenotificatiomanager = null;

public ibinder onbind(intent intent) {

@override
public int onstartcommand(intent intent, int flags, int startid) {
//初始化
messagenotification = new notification();

messagenotification.defaults = notification.default_sound;
messagenotificatiomanager = (notificationmanager)getsystemservice(context.notification_service);

messageintent = new intent(this, messageactivity.class);
messagependingintent = pendingintent.getactivity(this,0,messageintent,0);

//開啟線程
messagethread = new messagethread();
messagethread.isrunning = true;
messagethread.start();

return super.onstartcommand(intent, flags, startid);
}

/**

public boolean isrunning = true;
public void run() {
while(isrunning){
try {

thread.sleep(600000);
//獲取服務(wù)器消息
string servermessage = getservermessage();

messagenotificatiomanager.notify(messagenotificationid, messagenotification);
//每次通知完，通知id遞增一下，避免消息覆蓋掉
messagenotificationid++;
}
} catch (interruptedexception e) {
e.printstacktrace();
}
}
}
}

//或者，二選一，推薦使用system.exit(0)，這樣進(jìn)程退出的更干凈
