小编Bha*_*rat的帖子

我正在尝试连接我的远程unix机器并使用java程序执行一些ssh命令.

connection = new Connection(hostname);                                                  
connection.connect();
boolean isAuthenticated = connection.authenticateWithPassword(username, password);
if (isAuthenticated == false)
    throw new IOException("Authentication failed.");    
Session session = connection.openSession();
session.execCommand("sudo su - weblogic");  

这里需要密码和ofcrs,我无法提供,因为没有终端.因此创建了一个user.sh文件@我的unix用户主目录(/home/..../bharat),内容如下.

echo <mypassword> | sudo -S su - weblogic
sudo -S su - weblogic

但现在如果我像下面这样调用bash user.sh

session.execCommand("bash user.sh"); 

在我的用户使用java登录后,它会给出以下错误,但无法确定解决方案.

sudo: sorry, you must have a tty to run sudo
sudo: sorry, you must have a tty to run sudo

请帮忙 :)

发送的响应("cd /u02/app/oracle/xyz/admin/domains/11.1.1.9/xxxx_xx_xxx_xxx.domain/shared/logs/xxxx"); 在下面 -

突出显示的红色==>显示响应,我现在已经到了.

突出显示蓝色==>预期响应.

如果通过拆分相同的命令发送4个较小的命令,突出显示的绿色==>工作正常.

它的失败@下线 -

bindService(intent, m_serviceConnection, Context.BIND_AUTO_CREATE);

以下是追踪....

我已经搜索了很多关于这一点.在任何地方找到相同的代码,部分地解决了目的.正如API文档所述,它会在设备重启后重置计数器.有时,即使没有重启,计数器也会重置.下面是代码

float totalRxBytes = (float)TrafficStats.getTotalRxBytes()/(float)1048576;  // Received
float totalTxBytes = (float)TrafficStats.getTotalTxBytes()/(float)1048576;  // Sent
float mobRxBytes = (float)TrafficStats.getMobileRxBytes()/(float)1048576;
float mobTxBytes = (float)TrafficStats.getMobileTxBytes()/(float)1048576;
float wifiRxBytes = totalRxBytes - mobRxBytes;
float wifiTxBytes = totalTxBytes - mobTxBytes;  

但我无法想出任何方式从特定日期或一个月获得这些数据？请帮忙.任何指针将不胜感激.谢谢.

如下所示 - TelephonyManager仅提供SIM1的详细信息？

TelephonyManager  telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.isNetworkRoaming()

我无法弄清楚下面的代码有什么问题.我还检查了两次注册接收器.但事实并非如此.或者可能是我遗失了一些东西.可以请任何帮助.我真的需要它.:(

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.IBinder;

    @Override

        this.unregisterReceiver(this.br_call);
        super.onDestroy();
    }

问题

即使在使用START_STICKY之后,服务也不会始终运行.

有时候我没有得到任何Togoing Action for Outgoing,这是否意味着服务在一段时间后停止了？

我的要求

每当用户通过电话拨打电话时,应用程序都会显示Toast.为此,我使用BroadcastReceiver来点击调用操作和服务(始终运行Receiver).一旦我开始这项活动,它就会在拨打电话时开始显示吐司..但不是总是.

以下是完整的代码 -

MainActivity.class

public class MainActivity extends Activity 
{
    CallNotifierService m_service;
    boolean isBound = false;

    private ServiceConnection m_serviceConnection = new ServiceConnection() 
    {
        @Override
        public void onServiceConnected(ComponentName className, IBinder service) 
        {
            m_service = ((CallNotifierService.MyBinder)service).getService();
            Toast.makeText(MainActivity.this, "Service Connected", Toast.LENGTH_LONG).show();
            isBound = true;
            Intent intent = new Intent(MainActivity.this, CallNotifierService.class);
            startService(intent);
        }

        @Override
        public void onServiceDisconnected(ComponentName className) 
        {
            m_service = null;
            isBound = false;
        }
    };

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

        Intent intent …

任何人都可以帮助我解决问题吗？

public static void main(String[] args) 
{
    List<TestEnum> list1 = new ArrayList<TestEnum>();
    list1.add(TestEnum.ONE);
    list1.add(TestEnum.TWO);
    list1.add(TestEnum.THREE);

    System.out.println(list1);
    System.out.println(list1.remove(TestEnum.TWO));
    System.out.println(list1);

    System.out.println("-----------------------");

    TestEnum[] xx = new TestEnum[]{TestEnum.ONE, TestEnum.TWO, TestEnum.THREE};
    List<TestEnum> list2 = Arrays.asList(xx);

    System.out.println(list2);
    System.out.println(list2.remove(TestEnum.TWO));
    System.out.println(list2);
}

以下是结果 -

[ONE, TWO, THREE]
true
[ONE, THREE]
-----------------------
[ONE, TWO, THREE]

请帮助 - 为什么会这样,我还检查了哈希码？
