To generate or input text into an Android 4.0 (Ice Cream Sandwich) emulator, you can use several methods depending on whether you want to simulate an incoming message, paste text from your computer, or programmatically display text in an app. 1. Simulate an Incoming SMS
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.
Hardware Acceleration: Ensure "Virtualization Technology" (VT-x or AMD-V) is enabled in your computer's BIOS to prevent the emulator from being extremely slow. 2. Download the Android 4.0 System Image
# List available images sdkmanager --list | grep "android-14"3. Official Android SDK (Legacy)
- You can still download the old
android-sdk_r24.4.1-windows.zipthat includes the standalone emulator. However, it lacks security patches and suffers from modern host OS conflicts (Windows 11 HiDPI scaling breaks the UI).Launch with GPU acceleration (if host supports)
