Question

Am completely new to android development(from J2EE,Spring and Oracle background). Just trying to create a logo quiz app in android. Am planning my simple sqlite db structure to be,

1. unique image name
2. answer for the logo image(to check with user input)
3. whether answered or not (just a flag)
4. if answered, then points.

As soon as the user installs the app, the table has to be created with all the values. Now, my doubt would be, how to store this data? If i code this storing logic in an activity, then every time when the activity is started, would we be creating a new db and store it? where the coding logic for this initial storage would go?

Any help is much appreciated for this dummies question… Thanks in advance…

Answer 1

try this code to check wether or not your database is exist

private boolean checkDataBase(){

        SQLiteDatabase checkDB = null;

        try {

            String myPath = DB_PATH + DB_NAME;
            checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);

        } catch (SQLiteException e) {
            // TODO: handle exception
        }

        if(checkDB != null){
            checkDB.close();
        }

        return checkDB != null;
    }

so if it return true you don’t need to create a new database
