Displaying Data From MySQL Database
May 19, 2014
I am using a PHP script to convert my MySQL database data into JSON data. I am successful in doing so. Now I want to retrieve the data from my PHP script (on my localhost server) and parse that data and display it in a TextView. Everything runs fine, no errors, but the data is not displaying as I think it should. Here is my code for my MainActivity...
[HIGH]package com.example.testexternaldatabase;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.HttpEntity;
[code]...
I have a TextView called "result" and I gave permissions to access the internet in my manifest.

We have an android app that currently sends data to a php script which writes to a mysql DB on the same server. We are thinking of using a scalable remote DB e.g. amazon RDS.The question is how does our android app write to these remote DBs? Do they have some kind of rest API, or do we have to send the data to the same php script on our server but use that to post to the remote mysql DB?

I have an mysql database with some sports results in it. I want to write an android application to display these data on mobile phones.
I�ve searched on the internet for this issue and i think it is not possible to have a direct connection between the mysql database and the android application. (Is this right?)
So my question is the following: How can i have access in the android application to the mysql database in order to display some of the data?

I am currently looking in to developing an application for the android platform. I have some information that is stored within the SQLite Database of Android.
What I want to be able to do is to perform a query to the database table and populate a TableLayout with the information from the database table.
I have tried to find this on the Internet but have not had much luck. If anyone can help me to get about doing this would be great.

I'm trying to connect my program to a Mysql Database. The ling between my Android emulator and my server is OK, the ping is good. Moreother, I checked the connexion with a PhP script and everything is ok.
I would like to connect my program directly to the dataBase, using JDBC, et the J-connector. I added it to my project, and the code I use to etablish the connexion is :
Code:
private static final String DRIVER = "com.mysql.jdbc.Driver";
private static final String DATABASE_URL = "jdbc:mysql://10.0.2.2/annuaire";
private void initDb() {
try {
Class.forName(DRIVER);
[Code] .....
The problem is the I have an exception, and I don't know why. The fonction getConnection(DATABASE_URL,"root",""); throw the exception.Below, the screen shot with variables of the exception :

I'm trying to connect my app to a MySQL database to retrieve data. Obviously I have to do this in a new thread hence why I chose AsyncTask, something I'm new to.
I have included Toasts to tell me if there are problems when trying to carry out any part of it. However these toasts are not showing on the UI thread. I tested this out by turning off the server my SQL database is on so that it could trip the first toast. It didn't show it though and instead it gave me a force close error. When my server is running I have no issues and although I haven't coded the bit to retrieve data yet the code below does connect to my database and at least lets me view the page "CurrentSeasonDrivers".
Here is my code and the logcat showing the errors below that:
package com.android.history;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
[code]....
All I want it to do is show a toast if the application cannot connect to the server instead of force closing.

I wanted to fetch the title of an image which is saved in a mysql Db, I found out that you have to do this through Json, right now I am having a .php file:
PHP Code:
<?php
mysql_connect("localhost","xx","xx");
mysql_select_db("xx");
$q=mysql_query("SELECT title FROM field_title");
[Code]...
It outputs as follows:
Code:
[{"title":"titleone"},{"title":"titletwo"},{"title":"titlethree"}]
But now I am stuck, I want to put these titles in a simple arraylist but i don't know how to make the connection between the outputted data and the arraylist itself.
Code:
ArrayList<String> list = new ArrayList<String>();
for (??) {
list.add(string);
}
Is it possible to do this on an easy way?

I think this is the right place to look for some tips and stuff for android programming ahah. So I am completely new at all this java/android programming. My friend gave me the challenge to parse some json data as a listview. I was succesfully able to display the content as a textview however not everything appeared. Only the last few line of text showed up. He told me that by putting it as a listview everything should go well. Now setting up a listview isn't the same thing as setting up a textview. So my question is with all the code that I have how can I display the content as a listview.
[HIGH]DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams());
HttpPost httppost = new HttpPost("http://ec2-54-213-155-95.us-west-

I wish to display data in the the arraylist in a list view. The arraylist is not a generic list but a object defined by me. I want to display only certain data of the object. Something like, an object of a student, I want to display the student's name only, the student id and the student dob is not required.

My application needs to load and process some data at the startup which delays the displaying of the GUI quite a bit. I addressed that problem by starting a new thread to load and process the data. It solves the problem nicely, but is there a better way to do asynchronous processing in Android applications that I missed?

I have a Windows web server already set up with a website (unlimited application pools) and I want to be able to access a database on that server via the Android app I'm developing. How can I do this? Can someone point me to a tutorial or give code example of how this cross-platform (Android/Java to ASP.NET/C#) communication can be done? (I'm trying to create a leader board or global scoreboard for my Android game on my server.)

I created the following method for retrieving stored settings from the database:
public String getEntry(long rowIndex){
String value = "";
Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}
return value;
}
On debugging I can see cursor c contains two columns and one row but when it comes to line
String value = c.getString(columnIndex);
it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?

I am experiencing a problem where when the android device wake up from sleep, the Activity would take forever to get redrawn(and have to terminate it most of the time). I am not sure why, but when I comment out the code below where it retrieves an object from the database based on id stored in the bundle, the problem goes away.
Not sure why the db transaction is causing an issue.
secondly, is it better to store the object in bundle instead of storing its id and retrieving it from db in onCreate?
CODE:...............

If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?
