Which technique is commonly used to improve the performance of a native IoT application that frequently reads sensor data?

Reading sensor data in a blocking manner on the UI thread

Increasing the frequency of sensor reads

Storing all data in the cloud and fetching on demand

A developer is debugging a native Android app that communicates with a smart bulb over Wi-Fi using a custom TCP protocol. The app sometimes receives corrupted data packets. Which debugging approach is most effective?

Use a packet capture tool (e.g., Wireshark) on the same network to inspect the TCP traffic between the app and the bulb.

Switch to a hybrid web framework that uses WebSockets for communication.

Add a try-catch block around the socket read to handle exceptions.

Increase the socket timeout to allow more time for data to arrive.

A team is developing a native Android app for a drone controller. The app must display live video from the drone's camera with minimal latency, while also sending control commands. The team is considering using a native UDP socket for video and a separate TCP socket for commands. What is the primary reason for using UDP for video?

UDP guarantees packet delivery, ensuring no video frames are lost.

UDP is easier to implement in Android than TCP.

UDP has lower latency than TCP because it does not perform retransmission or congestion control.

UDP is more secure than TCP for video streaming.
