Android obtains software and hardware information and uploads it to the server (Socket Implementation). Android software and hardware

First, the project structure is shown in figure -- A: client-side CheckInfo and server-side CheckInfo_Server. CheckInfo obtains the mobile phone information (Mac, Cpu, memory, installed software information, etc.) and uploads the information to the server. Then, check whether a software has been installed from the installed software information, if not, go to the software download page. CheckInfo_Server outputs the uploaded information.

To obtain the mac address and communicate with the network, add ACCESS_WIFI_STATE and INTERNET permissions;

If any detected software (such as Kingsoft drug overlord) is installed in the mobile phone software, go to 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; @ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. main); tx = (TextView) findViewById (R. id. textView1); tx. setText ("Mobile Phone environment is normal") ;}@ Overridepublic 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 ;}}

If software such as Kingsoft drug overlord is not installed, you can find a webpage for download (the webpage here is only used for testing), and the Activity also jumps to 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; @ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. dsoft); wv = (WebView) findVie WById (R. id. wv); // set the page for loading the adaptive mobile phone screen WebSettings = 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, "error:" + e. getMessage (), Toast. LENGTH_LONG ). show () ;}@ Overridepublic 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 ;}}

Layout file:

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/plugin" android: paddingRight = "@ dimen/plugin" android: paddingTop = "@ dimen/plugin" 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 = "normal mobile phone environment"/> </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 receives software information and outputs it on the console:

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 .... "+" \ n "); // print the prompt information on the console; while (true) {Socket socket =. accept (); // obtain the connected socket object System. out. print ("Client Connected ...... "+" \ n "); // print the prompt information on the console; DataInputStream din = new DataInputStream (socket. getInputStream (); // obtain the input stream String msg = din. readUTF (); // read the message System from the client. out. print (msg); // console output information} catch (Exception e) {e. printStackTrace ();}}}

I just got started with Android and recorded my own examples to accumulate experience.

How does Android develop transmit bitmap and string from the client to the server using socket?

Socket can transmit arbitrary data. The key core is to define the "conversation protocol" of data packets "!
Files or data must be transmitted in multiple parts, so they cannot be sent all at once. Therefore, the key technology is simple.
Dialog protocol.

Android/java uses Socket to push messages similar to QQ messages. How can I keep the connection when the program runs in the background? How does the server determine whether the connection is disconnected?

QQ messages are UDP packets. After you connect, even if you do not close the connection, the server cannot determine whether the connection is closed,
Only the client regularly sends a UDP packet, indicating that the packet is connected.
