You can create an ASP.NET WEB API which returns data in JSON format which is a data format that is friendly with Mobile platforms and then consume the Web API from your android application check the official asp.net site for tutorials on getting started with ASP.NET WEB API.
http://www.asp.net/web-api[^]
Hope this helps.

My answer may help you to get this doubt clarified.
We can not connect to SQL Server or My SQL database from Android app. We need to have a middleware client to get this done. This is called "Web Service".
Basic flows of web service are (From mobile app perspective);
1. Generally Mobile application (In your case Android app) requests some data to web service.
2. Web service fetches data from backend (SQL Server & My SQL etc..) and passes to Mobile application.
3. Mobile Application processes the data.
So, My suggestion to you to connect to database from Android app is, You learn the basics of web service. Every mobile platform has got APIs to call web service.
Thank You,

You can download a zipped copy of the development kit that contains eclipse and the necessary things needed for developing Android application.
You can get the download from http://developer.android.com/sdk/index.html picking your OS platform.
Hope this helps. Happy coding.

To move from one activity to another in Android, you need an Intent.
The sample format of how to use an Intent is pasted below.
Intent intent = new Intent(context,NameofActivitytoMoveTo.class);
startActivity(intent);
Suppose you have ActivityOne in your android project and you want to navigate to ActivityTwo, use the sample code below:
Intent intent = new Intent(ActivityOne.this,ActivityTwo.class);
startActivity(intent);
The two lines of code above will be in the button onClickListener.
Hope this helps.
Happy coding.

Not in a forum like this. As a novice in all three disciplines you need to go and do a lot of studying to learn how to use these features. For Android go to http://developer.android.com/index.html[^]. For the others try searching for useful links with Google.

I don't have any more links than Google could find for you. Try refining your search parameters.

Hi
You can use mongoose web server (https://code.google.com/p/mongoose/[^]) for developing your rest server framework.
Integrate your project to include Mongoose and then specify the endpoints, handle them in your project.
Thanks,
Sudhi.

Hi,
I have just created a default Android Studio project with navigation drawer. The project was created with:
MainActivity.java
NavigationDrawerFragment.java
and
activity_main.xml
fragment_main.xml
fragment_navigation_drawer.xml
does this mean my startup will be an activity not fragment?
Do I need to change it?
I am trying to set the item actions in the navigation drawer like this:
private void selectItem(int position) {
mCurrentSelectedPosition = position;
Fragment fragment = null;
switch (position) {
case 0:
fragment = new WeatherFragment();
break;
case 1:
fragment = new WeatherFragment();
break;
case 2:
fragment = new WeatherFragment();
break;
default:
break;
}
if (mDrawerListView != null) {
mDrawerListView.setItemChecked(position, true);
}
if (mDrawerLayout != null) {
mDrawerLayout.closeDrawer(mFragmentContainerView);
}
if (mCallbacks != null) {
mCallbacks.onNavigationDrawerItemSelected(position);
}
}
so what this line should be:
fragmentManager.beginTransaction().replace(R.id.fragment_main, fragment).commit();
replace an activity or fragment.
Thanks,
Jassim
