Profiling Memory Usage in Android App with Retrofit and Room Integration
I'm wondering if anyone has experience with I'm trying to debug Recently started profiling an Android app that utilizes Retrofit for API calls and Room for local database persistence... After integrating these components, I noticed unexpected memory spikes, particularly during data fetching and storage operations. The app tends to freeze for a couple of seconds when loading large datasets, which is impacting user experience significantly. I've already implemented pagination in my Retrofit calls, which improved the loading times for the API responses. However, after retrieving the data, the transition to Room seems sluggish. Here's a snippet of the Retrofit call: ```kotlin interface ApiService { @GET("data/items") suspend fun fetchItems(): Response<List<Item>> } ``` Afterward, I insert the fetched data into Room like this: ```kotlin @Dao interface ItemDao { @Insert(onConflict = OnConflictStrategy.REPLACE) suspend fun insertItems(items: List<Item>) } ``` To diagnose the memory issues, I utilized Android Profiler and noticed that a large chunk of memory was retained after fetching and inserting the items. Despite using `LiveData` to fetch Room data, the UI seems to lag, leading me to wonder if I should optimize the way I'm observing changes from the database. I’ve tried switching from `LiveData` to `StateFlow` to see if it mitigates the lag, but the improvements were minimal. Another thought I had was to reduce the size of the data payload from the API. Do you think making the data model leaner would help? I've also explored applying the `@Transaction` annotation in Room to batch insert operations, as shown below: ```kotlin @Transaction suspend fun insertAll(items: List<Item>) { insertItems(items) } ``` Yet, the performance still seems compromised. It would be great to gather insights on best practices or patterns for optimizing memory management and performance for this specific integration. Any suggestions on how to improve the responsiveness of the app when handling large datasets would be incredibly helpful! For context: I'm using Kotlin on Ubuntu 22.04. How would you solve this?
