Review and fix Kotlin Coroutines issues in Android codebases by applying structured concurrency, lifecycle safety, proper scoping, and modern best practices with minimal behavior changes. Prefer edits that preserve existing behavior while satisfying structured concurrency and lifecycle safety. Common fixes: - Capture the exact error, crash, or symptom (ANR, memory leak, race condition, incorrect state). - Check project coroutines setup: kotlinx-coroutines-android version, lifecycle-runtime-ktx version. - Identify the current scope context ( viewModelScope , lifecycleScope , custom scope, or none). - Confirm whether the code is UI-bound ( Dispatchers.Main ) or intended to run off the main thread ( Dispatchers.IO , Dispatchers.Default ). - Verify Dispatcher injection patterns for testability. - ANR / Main thread blocking : Move heavy work to withContext(Dispatchers.IO) or Dispatchers.Default ; ensure suspend functions are main-safe.
