How does Android manage ContentProvider lifecycle and threading across processes?
Tests Android IPC and provider architecture. Strong answers explain lazy per-process instantiation via AMS, ContentResolver as the client binder proxy, and query executing on a binder thread. Red flag: claiming the provider runs in the caller process.
This tests Android IPC and ContentProvider internals. Strong answers cover: first, the system lazily instantiates provider in target process via ActivityManagerService when first queried, firing onCreate before first transaction; second, ContentResolver is the client-side URI resolver marshaling data across process boundary through binder; third, in provider process query runs on a binder thread pool thread, not main thread; fourth, the caller must use a background thread since it blocks during IPC.
