Android and Web work together (Android reads website-specific pages)

Project ideas:

To develop a website with web development knowledge, you must read the content of this module through android.

Implementation:

• You can use a mobile browser to directly read data. Advantages: you do not need to install a separate client. Disadvantage: some redundant information will consume the customer's traffic.
• An app implemented through a website has the following advantages: you can design an app for a mobile client to filter out other images and irrelevant content to save customer traffic. Disadvantages: the development cost increases.

Now we use technology to implement the second method: implement the android client by yourself.

1. Create your own site

Release, update, and delete the content of your website on the Web Internet for maintenance. I believe that there are a lot of charges and no fees, and you can find your satisfaction by searching for the Internet. This time we will focus on Android apps.

2. Create a view

This view is simple, that is, you can view all the current text content.

<?xml version="1.0" encoding="utf-8"?><ScrollView xmlns:android="http://schemas.android.com/apk/res/android"               android:layout_width="306px" android:layout_height="410px"               android:layout_x="7px" android:layout_y="61px"             android:scrollbars="vertical" android:fadingEdge="vertical">     <TextView      android:id="@+id/ResultView"      android:layout_width="fill_parent"      android:layout_height="fill_parent"      android:layout_marginTop="2px"     android:layout_marginBottom="2px"     android:layout_marginLeft="2px"     android:layout_marginRight="2px"     android:text=""     android:layout_x="7px"     android:layout_y="61px"     >     </TextView></ScrollView>

3. Create an app Project (internetactivity)

Httpget is used this time, similar to httppost. The specific code is as follows:

public class InternetActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {                super.onCreate(savedInstanceState);        setContentView(R.layout.rdbox);        TextView rbox=(TextView)findViewById(R.id.ResultView);                HttpGet post=new HttpGet("http://www.demon.com/");        try{        HttpResponse response=new DefaultHttpClient().execute(post);        if(response.getStatusLine().getStatusCode()==200){                String result=EntityUtils.toString(response.getEntity());                result=result.replaceAll("<", "");                result=result.replaceAll(">", "");            rbox.setText(result);        }        else{            rbox.setText("code:"+response.getStatusLine().toString());        }        }        catch(Exception ex){            rbox.setText("error:"+ex.getMessage().toString());            ex.printStackTrace();        }            }    }

Run, an error is found, and the content cannot be returned normally. After searching, the android permission is very strict and a line of code should be added to androidmanifest. xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="qiyesite.android.readbox"    android:versionCode="1"    android:versionName="1.0" ><uses-permission android:name="android.permission.INTERNET" />

It is important to remember the location. You must put it in the first-level directory under manifest. It is best to run it on the previous page.
