Is it possible to update SQLite database of android app outside app?I mean can user modify database according to them where the database situates in default location?
The default location is in /data/data/your-package/databases which is only accessible from your application. No other application is able to access it.
However in some special cases like rooted device, debug mode etc , it is still possible to access the database file and change it.
You can access the DB using Content Provider if you want to access it programmatically. Or If you just want to browse the data then you can follow this post.

I am Working on an Android Application which will be launched with a huge Pre loaded SQLite database. Problem is that database is visible to Applications like HACKDataApp etc. And Can also be viewed and copied in Android Device Monitor.
Question is, Is there any way to protect\hide my database from other applications??
you got to make your contentProvider not exported. SImply as that :
from official documentation :
android:exported: Flag allowing other applications to use this provider.
put this in your manifest declaration for each contentProvider.
I'm very new to android developing, and I'm making a project in my university for an app that backs up every other application's data to cloud. So in order to do this, I have to access it. Is it possible? And is there a way to do this without rooting the device?
The app that you want to create as backup use content provider in that app for insert,add, create, delete the data.That app work like a database for you.
For second app fetch the data from the first app.

i have one application with SQLite database and then i create another application that can connect to the database that i created one, my question is, is it possible connect the existing database without copying the existing once ? if possible can any one give me a sample code to connect my existing database . the name of my database is "SEIS" and the Table is Proinfo .
By default, each app's files are private to the app.
You could tell Android that your two apps should get permission to access each other's files by setting the sharedUserId attribute for both and signing them with the same signature, but the 'official' way to give other apps access to your data is to create a content provider.
Yes it is possible through the use of content providers. According to the documentation:
A content provider manages access to a central repository of data. A provider is part of an Android application, which often provides its own UI for working with the data. However, content providers are primarily intended to be used by other applications, which access the provider using a provider client object.
I suggest you read the following articles:

I know it is possible to access DataBase which in SDCARD by many apps in android.
but do not know the process to do that.
1- I created one test.db DB in sdcard eclipse .
2- My current app is using this DB.
3- I created one other app(which ll access this DB)
Please guide me How can i access test.db in my new app.
You can use the same database only if you created the running application database in custom content provider.
You cannot directly access the database from running application.
But if you create your running application database in Custom Content Provider then with the help of authorities you can directly access the database.
In this case you don't even need to copy that database.
Refer this link for custom content provider.
I am trying to build an app that will use an SQLite database. My question is once the database is created, will all data still be there once the app is closed, i.e.: the database won't be overwritten when the app is restarted?
You, as a developer are the only one who have access to this database, thus it is only your code which will be allowed to change the state or content of this database.
Yes, the data will remain there.
The data will remain there because of your default create method. There is a status code. You can use SQLScout http://www.idescout.com/ to visualize the table and watch its change step by step.
Yes, data will remain in your application when you close the application. When you run the application the database create in the application.
But yes, if the user uninstalls, the application then user will lose the application. On the other hand, if you want to save the data when the application is uninstalled, then it's better to create the database in SDCard.
