I am currently developing an Android app where users will input text, and I need to store that data in an online database for later retrieval. I have a LAMP server set up online that I can utilize.
Could someone guide me on how to connect Java with PHP and MySQL to achieve this? I'm unfamiliar with the process and wondering if there are other solutions worth exploring.
Appreciate any help. Thank you.
To access MySQL on an Android device, you would either need to find a compatible MySQL client library or develop one from scratch within your app. This would allow you to establish a connection to MySQL's TCP socket and manage the database directly.
However, exposing MySQL directly to the internet poses significant security risks. It is highly recommended to create a PHP middle-ware layer as a protective barrier to prevent unauthorized access to your database. Without this precaution, your valuable data could be at risk of being compromised by malicious hackers.
When setting up your LAMP server, it is important to create a web service API for your android application to communicate with. There are various security considerations to address depending on the type of data being transmitted or accessed. However, delving into those concerns is beyond the scope of this discussion.
After configuring your server side infrastructure, you can establish a connection to your website using the DefaultHttpClient class. The process may look something like this:
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://url.to.my.app.com");
HttpResponse response = httpClient.execute(httpGet);
// handle response
Alternatively, instead of developing and managing your own web service, you could opt to connect to a platform like Google Apps backend. Although some development work will still be required, addressing security issues may be more straightforward in this scenario.
