How do I display the names of the database entries added in a android application. I want when I click on search users it to bring up the names added in the database.

Answer 1

In short you would need to load the mysql jdbc drivers into your android application. I am not sure if this can be done. Android does not support connecting to a MySQL server out of the box as far as I know.

If you could include the mysql drivers into your android application by adding the mysql jdbc drivers jar to the application you would need to expose your MySQL server directly to the internet for the Android device to able to communicate to the server directly. NOTE By putting your MySQL server directly on the internet it is a open invite for hackers etc. to try and break into your database. Thus it is not advised that you expose your MySQL server directly to the internet.

Best solution is to create a web services or service of sorts that your device connects to. This service then retrieves the data from the database and returns it to your device.

load the mysql driver in android emulator .

In my case I developed a simple Camel IP server that sits between my device and the MySQL database. I used google protocol buffers to create a very simple RPC protocol and then I could upload files and data to mysql via the service and then also download and display data from the MySQL server via the service.
