aosp-ai-and-devices
aospbooks/aosp-internal-book
AOSP Part XII — AI & Devices. Use when reasoning about on-device ML in
AOSP, NNAPI, the AppFunctions framework for assistant integration, the
Computer Control flow, CompanionDeviceManager, or virtual devices
(virtual displays/inputs/cameras for cross-device experiences), or the
NpuManager module for on-device neural accelerators (model-load admission
control, the NDK ANpuBuffer surface, the android.hardware.npu HAL).
Chapters 51–53.
aosp-appendices
aospbooks/aosp-internal-book
AOSP Internals — Appendices. Use when looking up a key file path
(per-chapter table of the most important AOSP source files: build, init,
kernel, HAL, framework services, system apps, infrastructure) or the
meaning of an AOSP-specific acronym/term (Treble, VINTF, GKI, APEX, AIDL,
HIDL, etc.), why Kotlin is absent from the public API, or what changed from
Android 16 to Android 17. Reference material — load when you need a concrete
path, a definition, or a changelog rather than narrative explanation.
aosp-connectivity
aospbooks/aosp-internal-book
AOSP Part VIII — Connectivity. Use when reasoning about Networking
(ConnectivityService, Wi-Fi framework, netd, DNS resolver, VPN, tethering,
NetworkSecurityConfig, VCN, Thread mesh), Telephony (TelephonyManager,
PhoneInterfaceManager, RIL/RILD, modem AIDL, IMS framework, emergency
calling), Bluetooth (Bluetooth Mainline module, BTA, GATT, A2DP/HFP/AVDTP,
LE Audio, pairing, scanning, advertising), NFC (NfcAdapter/NfcService,
NCI, tag dispatch, HCE, secure element, reader mode, NFC-F/V), or USB &
ADB (USB gadget framework, host-mode USB, MTP/PTP, RNDIS tethering, adb
daemon, adb over Wi-Fi). Chapters 35–39.
aosp-device-support
aospbooks/aosp-internal-book
AOSP Part XIV — Device Support. Use when reasoning about per-architecture
support (ARM 32/64, x86_64, RISC-V, ABI matrix, toolchains), the QEMU-based
Android emulator (AVD format, hardware acceleration, guest kernel),
DevicePolicyManager (work profiles, fully-managed devices, COPE,
enrollment), Android Automotive / TV / Wear (CarService, vehicle HAL,
Leanback, TIF, Wear OS specifics), Print Services (PrintManager, IPP,
PDF generation), or the Camera2 pipeline (Camera2 API, CaptureRequest/Result,
camera HAL3). Chapters 59–62.
aosp-framework-core
aospbooks/aosp-internal-book
AOSP Part VI — Framework Core. Use when reasoning about system_server's
boot sequence (the four boot phases, service registration, Watchdog),
the Intent system (Intent matching, IntentFilter, IntentResolver, package
visibility, intent verification), Activity & Window Management
(ActivityTaskManagerService, WindowManagerService, activity lifecycle,
task/stack model, splash screens), the window system (WindowState,
SurfaceControl, input dispatching, focus, IME insets, transitions), the
display system (DisplayManagerService, logical vs. physical displays,
HDR, brightness, refresh-rate switching), or the View system (View
hierarchy, measure/layout/draw, Canvas/RenderNode, hardware acceleration).
Chapters 20–25.
aosp-framework-services
aospbooks/aosp-internal-book
AOSP Part VII — Framework Services. Use when reasoning about
PackageManagerService (install/uninstall, APK parsing, permissions,
package visibility), ContentProviders (ContentResolver, URI permissions,
observers, FileProvider, MediaStore), Notifications (NMS, channels,
ranker, posting/delivery, listener services, conversations, bubbles),
Power Management (PowerManagerService, wake locks, Doze, App Standby,
battery saver, BatteryStats), Background Tasks (JobScheduler, WorkManager,
AlarmManager, foreground services, exact alarm policy), Multi-User
(UserManagerService, profiles, restrictions, cross-user calls), Account
& Sync (AccountManagerService, authenticator, syncadapter, SyncManager),
Location (LocationManagerService, GPS/network/fused providers, GNSS HAL,
geofencing), or Storage (vold, StorageManagerService, scoped storage,
FUSE/sdcardfs, MediaProvider, SAF, FBE, adoptable storage, SQLite,
SharedPreferences). Chapters 26–34.
