首先，项目结构如图--A：分为client部分CheckInfo和server端CheckInfo_Server。CheckInfo获取手机信息（Mac，Cpu，内存，已安装软件信息等）并上传到server端,然后从已安装软件信息中查找有没有安装某一款软件，没有则定位到该软件下载页面。CheckInfo_Server将上传的信息输出。

}若安装的手机软件中有检測的软件（如金山毒霸）。则转到MainActivity.java,
MainActivity.java：
package com.xinab.checkinfo;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
TextView tx;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tx=(TextView)findViewById(R.id.textView1);
tx.setText("手机环境正常");
}
@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;
}
}
若没安装金山毒霸等软件。则定位到某一网页进行下载（这里的网页仅仅是測试所用），Activity也跳转到DsoftActivity.java：
DsoftActivity.java：
package com.xinab.checkinfo;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.widget.Toast;
public class DsoftActivity extends Activity {
WebView wv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dsoft);
wv =(WebView)findViewById(R.id.wv);
//设置载入的页面自适应手机屏幕
WebSettings settings = wv.getSettings();
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);
try{
wv.loadUrl("http://192.168.2.15:3000");
//wv.loadUrl("http://m.baidu.com/s?st=10a001&tn=webmkt&word=%CA%D6%BB%FA%C9%B1%B6%BE%C8%ED%BC%FE&f=web_alad_5");
}
catch(Exception e){
Toast.makeText(DsoftActivity.this, "错误:"+e.getMessage(), Toast.LENGTH_LONG).show();
}
}
@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;
}
}
布局文件：
main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="113dp"
android:layout_marginTop="127dp"
android:text="手机环境正常" />
</RelativeLayout>
dsoft.html:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<WebView
android:id="@+id/wv"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
CheckInfo_Server接收软件信息并在控制台输出：
server.java：
package com.xinab.checkinfo_server;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class Server {
public static void main(String aa[])
{
try{
ServerSocket as=new ServerSocket(8888);
System.out.print("Listenning...."+"
");//在控制台打印提示信息;
while(true){
Socket socket=as.accept();//获取连接的socket对象
System.out.print("Client Connected......"+"
");//在控制台打印提示信息;
DataInputStream din=new DataInputStream(socket.getInputStream());//获得输入流
String msg=din.readUTF();//读取client发来的消息
System.out.print(msg);//控制台输出信息
}
}
catch(Exception e){
e.printStackTrace();
}
}
}
刚接触安卓不久，把自己写的样例记录下来，以便积累经验。
