How can you effectively handle large JSON responses from a Retrofit API call to avoid OutOfMemoryErrors?
Android interview question for Advanced practice.
Answer
Both B and C are effective strategies for handling large JSON responses. Using a streaming JSON library (like Moshi with its streaming capabilities) avoids loading the entire JSON into memory at once. Pagination allows fetching data in smaller pages, preventing OutOfMemoryErrors. Increasing heap size (A) is a temporary solution and can lead to other performance issues. While compression (D) reduces the size, it still needs to be fully loaded into memory before processing.
