   A mobile app team is developing a fitness app that tracks steps, heart rate, and GPS routes. They need to test the app's performance under low battery conditions and with varying network connectivity. They have a limited number of physical devices. Which testing strategy would most effectively cover these scenarios while minimizing the need for physical devices?

   • AUse simulators for all testing because they are faster and can simulate all hardware features.
   • BUse emulators for all testing because they can simulate battery and network conditions accurately.
   • CUse only physical devices for all testing to ensure accuracy.
   • DUse emulators for functional and UI testing, and use physical devices for sensor accuracy and real-world network conditions.

   A tester needs to run an Android app on an emulator with a specific network condition (e.g., high latency) to test the app's behavior under poor connectivity. How can the tester configure this in Android Studio?

   • AConnect the emulator to a physical network and use a proxy to simulate latency.
   • BChange the emulator's build.prop file to modify network settings.
   • CUse the Android SDK's network tools to configure the emulator's network.
   • DUse the emulator's extended controls to set network latency and speed.
