There was a problem hiding this comment.
Restoring the optimization to call HttpUrl.get as part of Fetcher.fetch instead of part of Mapper.map as Fetcher.fetch is always called on a background thread.

This PR changes the default behaviour of the interceptor chain to be launched on the main thread by default. Why do this:
Interceptorsto be execute on the main thread synchronously if preferred.Interceptorscan also control which requests check the memory cache on the main thread by usingwithContextto change the current dispatcher when callingInterceptor.Chain.proceed.0.12.0. This realigns with that behaviour, but allows consumers to move the check off the main thread if they want maximum performance.This PR adds two new flags to
ImageLoader.Builder:launchInterceptorChainOnMainThread: Enables/disables launching the interceptor chain on the main thread.addLastModifiedToFileCacheKey: If the memory cache check occurs on the main thread, callingFile.lastModifiedcan cause a strict mode violation. This flag disables callingFile.lastModified. See Add option to disable adding File.lastModified to the cache key. #415 for context.Fixes: #280
