How can two processes in an Application, one an Activity and another a Service can use a common SQLite Database? This is not a question targeting very specific problem, but I looking for a solution from last three but no help.
Thanks for help.
You can write a ContentProvider which will do all the work with SQLite and both applications will use it to access DB.

I'm new to android development. I've started with an app on eclipse using java which uses a database of locations. My question is, how would I be able to connect my android app which to the database. Also suggest a suitable way of creating the database. Can I create it in mysql and then import in eclipse?
Look here.
I hope this will help you.
If you want to use MySQL to insert the data then use web service to send data in XML format from android to web service.
This link should explain everything that you need!

If you're just using this database for your application to store data, sqlite is a much better choice than mysql and integrates simply into android. I used the very same link above awhile back when I was getting into this stuff. The tutorial is structured in a very easy to read manner and explains everything as it goes. Good luck.
I am developing 2 application of android parallaly.Now i want to access one application data from another application i.e the data from folder data/data/com.sampleApp1.As both application will be developed by me so is it possible to access data of one application from another application if possible please provide solutions.Thanks in advance
If you're developing both applications you can use Shared User Ids. Both application will share permissions and files. Please be careful and check if you need/want this.

An another option would be a ContentProvider.
Please Refer Standard Content Providers Training Tutorial from developer.android
Please go through once you will not face any problem in future regarding Content provider

I dont know how to access different folder and whether it is possible or not. I think the best idea for you is to use content provider.

I have a few questions regarding sql server in android.
Essentially, I am tring to create an app that communicates to a SQL server, runs queries, creates new tables, rows, etc. I have been doing a lot of research recently about getting a connection to a SQL server in android. I've seen the tutorial on using a php file and it seems that isn't quite what I am looking for.
My questions:
Is it possible to create an app like the one I described above?
Do I need to do it using a php file? (like the tutorials)
Is there another way to do what I am looking to do?
Should I create a webservice to do the database portion of it? If so, are there any tutorials out there about that?
I apologize for my noob-y questions. Thanks for your help
You should definitely create a webservice, because otherwise any malicious user who has access to your app (downloads it) could easily trash your DB. But allowing insertion and creation privileges to users seems like a bad idea already.
If your users need a personal db, why don't you use sqlite which is stored locally and has no access delays, and no internet connection requirements? Why do you want a single db that is completely exposed to everyone?
It is not a good idea to communicate directly to SQL server from Android Phones. You might hit so many technical constraints when you keep going with the development. I am not sure about he end result as well. It would be great to go ahead with the service that way you might have lot of controls inside the application and design it efficiently... Just a thoughts :)
Is it possible to successfully use Sqlite on Android without also having to use a ContentProvider?
Can someone show me a sample that doesn't use ContentProvider?
And if it is indeed true that Sqlite can be successfully used without it, what are examples of cases where ContentProvider would be necessary?
This site does an excellent job describing how to use SQLite in Android without managing to ever once use the term 'ContentProvider.'
A simple Google search such as Android SQLite tutorial -"ContentProvider" will show many many more examples.
Google is your friend.
You need to be aware that SQLite database isn't thread safe, so if you intend to have more than the one thread running at any time accessing the database, you'll definitely run into more problems than in implementing a ContentProvider.
I strongly recommend having a ContentProvider as you can bake all the difficult SQL that cannot be mapped to ContentProvider queries into URIs instead.
I wish to use database for my application.How to use the database in android.I use eclipse ide.Is there any requirements need for create database.Give some basic ideas about it.I am android beginner.Help me to know about it.
Since this question is worded almost exactly like how to use database in android? I would say you created a duplicate question. if not, see that question. If you need more, supply the info you would like to the initial answerers.
I think you should see Notepad sample project. There are a lot of common android practices there including database stuff.
