Android Runtime, Context, and Component Discovery

Explain how Android processes, the application sandbox, the main thread, and component instances interact at runtime.

Choose the correct Context type for operations with different lifecycle and UI requirements.

Trace how manifest declarations and intent filters make an Android component discoverable to the system.

Construct explicit and implicit Kotlin Intents with correctly typed data, categories, extras, and flags.

Predict how Android resolves an implicit Intent—including package-visibility effects—and safely handle zero, one, or multiple matches.

Inspect installed components and Intent resolution results using PackageManager and adb.

Configure Application-level initialization without retaining short-lived Contexts or blocking the main thread.

Use StrictMode to detect main-thread disk or network access and leaked closable objects.
