Section B — Practical configuration and troubleshooting (30 points) 5. (10 pts) Given a development machine with 8 GB RAM and an Intel CPU supporting virtualization, specify an optimal AVD configuration for testing a mid-range Android 4.0 phone (include system image choice, RAM, heap, storage, screen resolution, and GPU settings). Justify each choice briefly. 6. (10 pts) Your Android 4.0 emulator is extremely slow to boot and UI interactions are sluggish. List a prioritized troubleshooting checklist (5–8 steps) you would perform to identify and fix the performance problems. For each step, state the expected result and why it helps. 7. (10 pts) App crashes on the emulator but runs fine on a real device. Provide five plausible causes specific to emulator behavior and how you would test or mitigate each cause.
