Can My Android App Directly Access a Remote MySQL Database?

Accessing an Online MySQL Database from an Android App

Can an Android App connect directly to an online mysql database?

Yes, it is possible to establish a direct connection between an Android app and an online MySQL database.

Requirements:

1. Web server with a MySQL database
2. Android development knowledge
3. Web service (JSON, XML, etc.)

Steps:

1. Internet Permission:

   • Enable internet access in the AndroidManifest.xml file:

     <uses-permission android:name="android.permission.INTERNET"/>

2. HTTP Request Class:

   • Create a class (e.g., JSONfunctions) to send HTTP requests:

     public static JSONObject getJSONfromURL(String url) {
       // Request and retrieve JSON data
       ...
     }

3. HTTP Request in Activity:

   • In the main activity, make an instance of JsonFunctions and provide the database URL:

     JSONObject jsonobject = JSONfunctions.getJSONfromURL("http://YOUR_DATABASE_URL");

4. Parsing Response:

   • Read the JSON tags and store the data into an array list for display.

Alternative Approaches:

Since API 23, HttpClient and HttpPost have been deprecated. Consider using HttpURLConnection or third-party libraries such as Volley or Retrofit for API calls and parsing with Jackson or Gson.
