Problems to enable remote access SQL Server + Android

Question

Good afternoon I made a webservice on Asp.net, and I need to access it through an android application. In any normal function, it works normally, but if it is a function that has access to the database, it causes the following error:

A network-Related or instance-specific error occurred while establishing a Connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote Connections.

After some searches, I saw that I had to enable an option in SQL Server Management, making the remote access enabled, however, I use the local database of Visual Studio and not SQL Server itself. How to proceed?

First you have to see if there are any firewalls blocking SQL Server (on your computer or server). Port 1433 is the default.

After you have to go in the settings of SQL Server and set this option. Here is a good tutorial: http://blog.citrix24.com/configure-sql-express-to-accept-remote-connections/
