Android SDK vs MEAN: What are the differences?

1. Development Technology: Android SDK is specifically for developing native Android applications using Java or Kotlin, while MEAN (MongoDB, Express.js, Angular, Node.js) is a full-stack JavaScript framework used for building web applications.

2. Platform Support: Android SDK is primarily focused on Android mobile devices, whereas MEAN Stack can be used to develop web applications that can run on various platforms including browsers on desktops and mobile devices.

3. Database Integration: Android SDK provides built-in support for SQLite database for local storage in Android apps, whereas MEAN Stack uses MongoDB, a NoSQL database, for efficient data handling in web applications.

4. Real-time Data Processing: MEAN Stack, with the help of Node.js and Socket.io, allows real-time data processing and communication, which is not a native feature in Android SDK without using additional libraries or services.

5. Front-end Framework: Android SDK does not include a specific front-end framework and mainly focuses on the development of the user interface using Android XML layouts, while MEAN Stack combines AngularJS as a front-end framework for building dynamic single-page applications.

6. Server Configuration: In Android SDK, server-side configurations are minimal as the app interacts with external servers or APIs, whereas MEAN Stack allows developers to configure the server-side logic using Node.js and Express.js for better control and customization.

In Summary, Android SDK focuses on native Android app development, while MEAN Stack is a JavaScript-based framework for versatile web application development.
