Use existing Sqlite database in Android

Hello,

Since last few days, I have been working with android and I am very excited about it. This is my first blog on Android and many more is to come.

Normally Sqlite database is used with Android application. So this blog is about how you can use existing Sqlite database in Android application. First you need to add following table in your database. I recommend Sqlite  Expert Personal tool to make changes or create new Sqlite database. Open the database and run following query

"CREATE TABLE "android_metadata" ("locale" TEXT DEFAULT 'en_US')"

After that insert record in it.

"INSERT INTO "android_metadata" VALUES ('en_US')"

Once done add your database file in assets folder of your android application. You can do simple copy paste here.

Now we will create class which will have all database related functions and methods. We will use SQLiteOpenHelper class provided by Android framework to connect with Sqlite database. Following is the class definition.

public class DatabaseAdapter extends SQLiteOpenHelper {

         private static String dbPath= "data/data/com.YourPackageName/applicationDb/";
         private static String dbName = "YourDBName";
         private SQLiteDatabase applicationDatabase; 
         private final Context applicationContext;

       
         public VocabTesterDatabaseHelper(Context context) {
                 super(context,  dbName , null, 3);
                 this. applicationContext  = context;
         }


         private boolean checkDataBase(){
                 File dbFile = new File( dbPath +  dbName);
return dbFile.exists();
  }


          private void copyDataBase() throws IOException{
try {

                  InputStream input =  applicationContext .getAssets().open(dbName);
                           String outPutFileName=  dbPath  +  dbName ;
                     OutputStream output = new FileOutputStream( outPutFileName);
                      byte[] buffer = new byte[1024];
                  int length;
                  while ((length = input.read(buffer))>0){
                 output.write(buffer, 0, length);
                  }
                  output.flush();
                  output.close();
                  input.close();
       }
                       catch (IOException e) {
                    Log.v("error",e.toString());
                    }
   }


             public void openDataBase() throws SQLException{
                String fullDbPath= dbPath + dbName;
             applicationDatabase = SQLiteDatabase.openDatabase( fullDbPath,     null,SQLiteDatabase.OPEN_READONLY);
   }

                @Override
public synchronized void close() {
       if( applicationDatabase != null)
        applicationDatabase .close();
             super.close();
}
@Override
public void onCreate(SQLiteDatabase db) {
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}

}

That's it and your database helper class is ready. Initially we placed database in Assets folder and later on we moved it to particular folder in application. Still I am working on this class so I will add more functions to class and at the same time, I will upgrade this post. Stay tuned.

Thanks.

Case Study: Infusionsoft API Integration with Magento

Hello,

Here is another case study blog. My earlier case study blog was on ChannelAdvisor API  integration with Magento. You can read it here . Recently we were working on a Infusionsoft API integration with Magento.

What is Infusionsoft?

Infusionsoft helps small businesses in terms of marketing automation. They help small businesses to convert leads, grow sales and save time. They have CRMs which helps customer to centralize all their data at one location which can be easily accessible from anywhere. With their Email marketing customer can create emails which helps them in increasing sales and getting new clients. With their automation customer can create a system which can trigger behavior based communication, workflow  which helps them saving time and managing their sales and marking process.

Also they give nice set of REST APIs using which, it can be connected to ant third party applications and that was main requirement of our project.  Imagine the scenario that you have an Magento eCommerce site where you have thousands of customers registered and you are planning to use Infusionsoft as a primary service for your marketing.  In this case you need something between Magento and Infusionsoft  that can communicate user information.

We integrated Infusionsoft API with Magento registration. So that whenever a new user registers in Magento, their details automatically sent to Infusionsoft database using API. In case user updates information in Magento same  information is updated in Infusionsoft too. In case Admin deletes  user account, that particular user will be removed from Infustionsoft database  too.  This is the complete integration of Infusionsoft API with Magento.

This is very useful in case you have some user preferences in Magento database and based on that you want to send them marketing emails and in many other cases.
