🧵Cracking the Interview: Multiple Threads and Interview Questions in Android 📱
In Android development, using multiple threads can drastically improve performance and solve problems related to tasks that may block the main thread, such as network calls, database operations, or complex calculations. In this blog, we’ll explore how to effectively use multiple threads to resolve issues in Android apps, and I’ll guide you through the concepts with examples, as well as the best practices. 🚀
🤔Why Use Multiple Threads?
Android runs on a single main thread (also called the UI thread), which is responsible for handling user interactions, updating the UI, and running tasks like network calls or database queries. However, performing heavy tasks on the main thread can cause UI freezing or application crashes, as it can’t respond to user actions while processing those tasks.
Solution: Offload these tasks to background threads, allowing the main thread to remain responsive and providing a smooth user experience.
🛠️Common Use Cases for Multiple Threads
- Network Operations: Downloading or uploading data from/to a server.
- Database Operations: Fetching or writing large datasets.
- Heavy Computations…
