Section C — Commands, logs, and debugging (25 points) 8. (10 pts) Provide the adb and emulator commands (with exact syntax) you would use to: a) Start an AVD named "Android_4_0_AVD" from the command line. b) Push a debug APK (file: app-debug.apk) into the emulator and install it. c) Capture logcat output filtered for your app’s package "com.example.app" and save to a file named "app_log.txt". d) Forward a host port 8000 to the emulator’s port 8000. For each command, briefly state the expected output or effect. 9. (15 pts) You see the emulator’s system log showing frequent "GC_FOR_ALLOC" messages and OutOfMemoryError for a native allocation. Explain what these messages mean, how they relate to emulator configuration and app behavior, and list four concrete fixes (two app-level, two emulator/AVD-level) you would apply.
