How do I communicate Struts 2 web server to an Android App (Client Server) in Java?

Communicating Between Struts 2 Web Server and Android App (Client-Server) in Java

Establishing communication between a Struts 2 web server and an Android app involves several steps. Here's a guide:

Step 1: Define Communication Protocol

1. Choose Communication Protocol:
   • Determine the communication protocol (e.g., RESTful APIs, JSON, XML) for data exchange between the Struts server and the Android app.

Step 2: Web Services Integration

1. Create Web Services:
   • Develop RESTful APIs or services using Struts 2. These services will handle incoming requests and return appropriate responses.

Step 3: Android App Development

1. Networking Setup:

   • Implement network-related classes (like HttpURLConnection or libraries like Retrofit or Volley) in your Android app to send HTTP requests to the server.

2. Handle Server Responses:

   • Receive and parse server responses in the Android app, whether they are in JSON, XML, or other formats.

Step 4: Establish Connection

1. Send HTTP Requests:
   • From the Android app, send HTTP requests to the specific endpoints (URLs) of the Struts 2 server using appropriate methods (GET, POST, etc.).

Step 5: Implementing Data Transfer

1. Data Serialization/Deserialization:
   • Serialize data from the Android app before sending it to the server and deserialize the received data from the server response.

Step 6: Recommended Learning Resources

1. Tutorials and Documentation:
   • Explore online tutorials covering RESTful APIs, networking in Android, and Struts 2 web services for a better understanding.

Step 7: Seeking Guidance

1. Online Courses or Coaching:
   • Consider seeking guidance from experienced tutors or institutes on UrbanPro specializing in Java, Android app development, and Struts 2. They offer courses tailored to communication between server-client applications.
