Its an excellent tutorial for android DB CRUD with
COMPLETE SOURCE CODE

regards nyasha
public class dataHelper extends SQLiteOpenHelper{
private final Context myContext;
private static String DB_PATH = “data/data/android.vineetyadav.com.dbTest/databases/”;
private static String DB_NAME = “Myfirst.db”;
private SQLiteDatabase myDatabase;
public dataHelper(Context context) {
super(context, DB_NAME, null, 1);
this.myContext = context;
}

public void createDataBase() throws IOException{
// TODO Auto-generated method stub
boolean dbExist = checkDatabase();
if (dbExist) {

}else {
this.getReadableDatabase();

try {
copyDatabase();
} catch (IOException e) {
// TODO Auto-generated catch block
throw new Error(“Error copying database”);
}
}
}

private void copyDatabase() throws IOException {
InputStream myInput = myContext.getAssets().open(DB_NAME);
String outFile = DB_PATH+DB_NAME;
OutputStream myOutput = new FileOutputStream(outFile);
byte[] buffer = new byte[1024];
int length;
while((length = myInput.read(buffer)) > 0) {
myOutput.write(buffer, 0, length);

}
myOutput.flush();
myInput.close();
myOutput.close();
}
private boolean checkDatabase() {
SQLiteDatabase checkDb = null;
try {
String myPath = DB_PATH+DB_NAME;
checkDb = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);
} catch (SQLiteException e) {

}

if (checkDb != null) {
checkDb.close();
}
return checkDb!= null ? true:false;

}

public void openDatabase() throws SQLiteException {
String myPath = DB_PATH+DB_NAME;
myDatabase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);
}
@Override
public synchronized void close() {
if (myDatabase != null) {
myDatabase.close();
}
super.close();
}
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub

}
public Cursor doQuery(String query) {
Cursor c = myDatabase.rawQuery(query,null);
return c;
}
}

queryString = query.getData(“data.xml”, columns, “_id =” + id, null, null, null, null, null);

From there you can have am EditText and save it to a String title and query the DB with the string.

In theory lol.

Now, I was wondering how I can input data into my DB outside of an activity. When I remove the “extends activity” from the class it shows error for the line

query = new DatabaseQuery(this);

I need to have this run from a service that auto downloads and inputs the data every minute without calling an activity. The service works but when it calls the activity to input data everything else goes to onPause and the input data activity takes focus then closes. Then the screen flashes and the main activity goes to onResume and refreshes.
