Android VMD MySQL插入和显示对话框

Question

I am trying to do a simple insert from an Android application. I can run my php script from the browser by concatenating ?entry="Sample value from browser" , but when I run the application from Android, I get no insert.

Here is where I am calling the insert class that uses JSON and implements AsyncTask:

package us.jtaylorok.android.sqlite.first;

import java.util.ArrayList;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

import android.app.ProgressDialog;
import android.content.Context;
import android.os.AsyncTask;
import android.util.Log;
import android.widget.Toast;

public class RemoteInsert extends AsyncTask<Void, String,String >{

    protected String TAG;
    protected Context context;
    protected String input;
    protected ProgressDialog progressDialog;

    public RemoteInsert(String i,Context c){
        this.input = i;
        this.context = c;
    }


    protected void onPreExecute() {
        //ProgressDialog progressDialog; // = new ProgressDialog(context);

        //progressDialog=ProgressDialog.show(,"Please Wait..","Sending data to database", false);
        progressDialog=ProgressDialog.show(context,"Please Wait..","Sending data to database", false);
    }

    @Override
    protected String doInBackground(Void... params) {
        try {
            HttpClient httpclient = new DefaultHttpClient();
            //HttpPost httppost = new HttpPost("http://localhost/index.php");
            //HttpPost httppost = new HttpPost("http://10.253.8.88/patient_data/patient_data.php");
            HttpPost httppost = new HttpPost("http://10.100.205.72/patient_data/patient_data.php");

            ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
            postParameters.add(new BasicNameValuePair("entry", "Input from Android"));

            httppost.setEntity(new UrlEncodedFormEntity(postParameters));                   
            HttpResponse response = httpclient.execute(httppost);
            Log.i("postData", response.getStatusLine().toString());
        } catch(Exception e) {
            Log.e(TAG, "Error:  "+e.toString());
        }  

        return "";
    }

    protected void onPostExecute(String result) {
        progressDialog.dismiss(); 
        Toast.makeText(context, "Finished", Toast.LENGTH_LONG).show(); 
    }
}

And here is my PHP script:

<?php
    // mysql_connect("host","username","password");
    mysql_connect("localhost","user1","mypassword");
    mysql_select_db("test");

    $entry_value = $_REQUEST["entry"];
    $query = "INSERT INTO patientdata (entry) values (".$entry_value.");";
    if( !mysql_query($query) ) { 
        /*insert failed*/ 
    }

    mysql_close();
?>

Again, this works perfectly if I call it from the browser, but it throws an exception before implementing AsyncTask .

I do get the AVD to display the add and remove, but when I do that there is no request in my apache2 access_log or error_log . Any suggestions?

Answer 1

I think you have stored php script on local server. So use this 10.0.2.2 while initializing HttpPost instead of your machine's ip address. Its localhost equivalent in android Virtual device.

Answer 2

That was not the issue for this particular problem. The issue was a magic quotes setting in the php.ini
