Android :: Web Access To Database

Dec 7, 2009

I would like to ask you smart people if anyone has seen any documentation regarding web access to a database from within an Android application. I would like to create a (FREE) application where the users can share information (rants/complains) around the globe. Each user will be able to see a little globe in his phone with locations of other users and some specific information about them.

Architecturally, I am thinking "database in my GoDaddy host, exposing a web service", and the web service accessed from the Android application. But I see no documentation about accessing web services. I can also go XML, maybe, but I am not seeing what mechanisms exist in the Android for over-the-web XML access.

I have a feeling I am mis-understanding something big in the picture. Can someone point me to docs, or knows something about this topic? (the iPhone has a Lighter app where you can see people lighting around the globe. Mine is similar, but people would not be lighting, instead they will be "complaining/ranting").

Android :: Access Database

May 26, 2010

I am working on a Android app and I have a dilemma. I have a list of Objects. I have to update each of these objects with a database. I have 2 methods:

Method 1:I can loop through the Objects. For each object I can connect to the server, update it, and then move on to the next Object, and so forth.

Method 2:I can store the Objects in a list, send the whole list to the server, update it on the server side, then return a list of updated objects.

My questions are:

Which method is faster?
Which method is easier on the phone's battery?

Android :: Database Access / How To Close It

Aug 2, 2010

I am creating an android app that is basically a listing of information on Mushrooms. I get this information from an sqlite database. I have a global singleton with a services class inside it in which I use to access my db. Almost every activity accesses the db. Is it better to leave my db open all the time or open and close it as I need the data? If the best practice is to leave it open all the time, where do I need to make sure to close it and what is the worst case scenario if I left it open when the activity was destroyed?

Android :: Access Data In An ASP.NET Database Via App

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.)

Android :: Database Access Across Tabs

Jul 22, 2010

I have four tabs (reports, review reports, map and settings). I have an sqlite database populated with report information. I wish to have the database accessible throughout the application. The reports tab successfully adds data to the database however using the same methodology crashes the application. The Android debugger points to the line where the database is called again.

In the reports tab the following code is used to launch the database...

CODE:.................

In the onCreate() method of the Review Tab - Where I wish to review reports - I try to access to the database through the call calling the return report method

this.reportDatabase = new ReportDatabase(this);

However this fails to work. In the android debugger highlights that the problem belongs with the context being provided to it. I realise that the report database has already been accessed by the report tab and wonder if this is causing the issue. I am new to programming android, the application is designed to report on flamingos in Africa, any help would be greatly appreciated!

Following the suggestion of Seva Alekseyev I have adapted as follows...

I have adapted my ReportDatabase as...

CODE:..............

using...

reportDatabase = ReportDatabase.open(this);

As the call in both the report and review tab. Unfortunately this doesn't seem to work, the debugger stops on the same method. The full ReportDatabase.java file is here...

CODE:...........


This method returns a double array and probably shouldn't be this hacky...

CODE:............

With the error stack being...

Android :: Data Passing And Database Access

Sep 23, 2009

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?

Android :: Database Access Design Approach

Aug 30, 2010

I have a general Android design question around data access. I have a number of activities in my application that need to access a SQLite database. In order to wrap up all data access logic in one place I have created a DatbaseHandler class that takes care of all data access logic. This class takes care of building up where clauses, calling the database and interrogating the resulting cursor to retrieve the query results and return them to the caller. The purpose of this class is to wrap all data access code in one place so that it can be easily managed and maintained as opposed to having data access logic scattered across all activities. Each activity that needs access to the database creates an instance of this DatabaseHandler class and passes it a reference of android.content.Context. The DatabaseHandler class then uses this Context object to call an underlying content provider as follows context_i.getContentResolver().query(...).

My data access logic (cursor handling logic to be specific) is not in the activity and so I cannot manage the cursors life cycle, therefore there is likely to be memory leaks.

My questions are as follows -

How can I (if its even possible) manage the cursors life cycle from outside an Activity? Should each activity even be creating an instance of this data handler class and passing an instance of Context to it? Perhaps my design approach is wrong and I should expose these data access functions as static methods that take an instance of the calling activity as a parameter. That way I could perform managed queries and let the activity take care of managing the cursors life cycle?

Android :: Prevent Access To SQLite Database

Oct 18, 2010

I use a sqlite database in my project. The stored data in it must not be available for the user to edit. As I've read here I saw that if you have root access you can alter sqlite database. The only solution would be to encrypt database content, but this would be time consuming for device. Any solution to prevent access to database ?

Android :: Direct Database Access Instead Of Content Providers

But since the examples I've seen all use content providers, I'm not sure how to proceed without them and populate activities with data derived from accessing my application's database directly.
