Use Of SQLite

 

This is a sample program which shows usage of SQLite in android application for saving data. This application has two buttons in the main menu one for saving information and another for showing all saved information. Last blog published in this forum is How to handle bluetooth settings from your application.

Underlying Algorithm:

Basic description of algorithm in step by step form:
1.) Create a Project DatabaseSample.
2.) Replace the following code with res/layout/main.xml :

 

 

 

3.) Create a helper class DataManipulator.java that can create the database and encapsulate other SQL details. In this DataManipulator class we will include an important inner class OpenHelper that provides a SQLiteOpenHelper.

 

 

 

4.) Create a save.xml in res/layout/save.xml:

 

 

 

5.) Create a Activity SaveData.java to Save the information :

 

 

 

6.) Create a ListView to show the all data in a list in res/layout/check.xml :

 

 

 

7.) Create a Activity CheckData.java :

 

 

 

9.) Run the Application.

Steps to Create:

1.) Open Eclipse. Use the New Project Wizard and select Android Project Give the respective project name i.e. DatabaseSample. Enter following information:
Project name: DatabaseSample
Build Target: Android 2.1
Application name: DatabaseSample
Package name: com.app.DatabaseSample
Create Activity: DatabaseSample

On Clicking Finish DatabaseSample code structure is generated with the necessary Android Packages being imported along with DatabaseSample.java. DatabaseSample class will look like following :

You are always welcome.

Thanks.

Hi when i am trying to build the application it is saying the no compatable avd with 2.1 version. and build is not complete

Reply
    Sushant says July 18, 2011

    You might be using mismatched build and AVD version.

    To add a new AVD in eclipse:

    * Window => “Android SDK and AVD manager”
    * New

    Check what version you are using in your project and create a new AVD with that target version.

    Thanks..

Hi shusant,
when ever i run the program and click to any function it say “This king of launch is configured to open the debug perspective when it suspends.
This debug perspective is designed to support application debugging. It incorporates views for displaying the debug stack variables and breakpoint management.”

what it means and what is the error i am repeating which gives this.
plz help me in this

Reply
    Sushant says July 26, 2011

    You might not running your app. You are debugging it. You can do following to fix this problem:

    1.) Press Ctrl+F11 and run your app instead of start debugging.
    2.) Go to Run->Remove All breakpoints and then run your app.

    The message you are getting is debugger message.

Hi Sushant,

I am new to android programming and I am a student. I am working on a project similar to DNA-Alignment given in this site “https://market.android.com/details?id=blink.dna.align&feature=search_result#?t=W251bGwsMSwxLDEsImJsaW5rLmRuYS5hbGlnbiJd” but I am using Boyer-Moore Algorithm to align the strings. I have done with the framework “main.xml” but I’m getting confused as I don’t know how to manipulate the comparison step by step in android using indents as shown in this java applet “http://home.avvanta.com/~doyle/bmi.html”. Please help me as I am working on my final project for my academics. I am looking forward to hearing from you!

I hit the same problem with the Force Close, and looked at my logs. This showed:

FATAL EXCEPTION: main
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.app.DatabaseSample/com.app.DatabaseSample.SaveData};

I checked my code against the source code, and found the activities missing from the manifest xml:

Now it WORKS!! This was a good activity for me, not only did I learn about integration with the sqllite database, but also a good example of using multiple activities. I am going to build a similar app, and will post a link back here.

THANKS FOR THE GREAT EXAMPLE!!!

Hi Sushant,

Great article, thanks.

I just started learning Android, and hope you can help with a question of your sample app. In the app, the background is black, while the text’s foreground is white. That seems to be opposite to the default color setting. Could you let me know how you achieved that? I tried looking through the sample code, but couldn’t figure out.

Thanks for your help.

Nice looking app. However when I load the code into Eclipse I get an error in the onClick(View). I loaded the code into a Android project from existing code. When I look at the build properties it tells me that it is using 2.3.3. Could this be the reason that I’m seeing these error.
