Full details: Description checkExplanation The description explains the overall objective, emulator testing, and planned next steps, but it omits the required Changes Made section and does not describe the implementation details. The PR changes UI behavior, but the required Screenshots & Videos section is also missing. Resolution Add a Changes Made section that describes CourseGrabRepository, the migrated activities and service, and the networking cleanup. Add Screenshots & Videos for the UI changes, or remove the section only if UI behavior did not change. Expand Test Coverage with specific test steps and scenarios.

responses are accepted only for the latest request, not merely when the current
text matches query. Track a monotonically increasing request ID or cancel the
previous search job, and validate that identity before updating the UI,
including repeated searches for the same text.

sendRegistrationToServeraccepts a nullable token and then sendstoken.toString()to the backend. Iftokenis ever null/blank, this will register the literal string "null" (or an empty token) on the server. Guard against null/blank tokens before sending.
private fun sendRegistrationToServer(token: String?) {
CoroutineScope(Dispatchers.Main).launch {
repository.sendDeviceToken(token.toString())
}

sendRegistrationToServercurrently callsrepository.sendDeviceToken(token.toString()), which can send the literal string "null" if the token is null/blank. Add a null/blank guard so invalid tokens aren’t registered on the backend.
private fun sendRegistrationToServer(token: String?) {
lifecycleScope.launch {
repository.sendDeviceToken(token.toString())
.onSuccess { Log.d(TAG, "sendRegistrationTokenToServer($token)") }
.onFailure { Log.w(TAG, "Failed to register device token", it) }

- The error message "Server error (code)" is misleading for non-2xx HTTP responses like 400/401/403, which are not necessarily server-side faults. Consider using a neutral "HTTP error" message (or differentiating 4xx vs 5xx) to avoid confusing users and logs.
ApiException(
if (httpResponse.isSuccessful) "Unreadable response from server"
else "Server error (${httpResponse.code})"
)

I didnt look super close into it, but if it works on your end it should be fine. Mab could split into 2 prs with cleanup in one and change in the other. LGTM
Overview
Originally, the codebase did not utilize a clear abstraction for the repository layer. This PR implements it, along with some cleanup work.
