    When no file filters are specified in the server whitelist, the Android system is incorrectly given a mime type filter list including a single empty ("") mime type. Naturally, nothing matches this, and no documents can be selected for upload.

    To remedy this, the application is changed to return a null filter array if filters are not to be applied.

Rather than using the Kotlin apply function, directly invoke the builder methods on the OkHttpClient.Builder instance. This produces noticeably better bytecode and the apply function does not add value in this case.

Rather than creating a new, unsized HashSet, use idiomatic Kotlin to create the set of RequestListeners for the ImagePipelineConfig. Under the hood a SingletonSet will be used which is optimized for the current use case, but if additional Listeners are added, the collections will automatically be sized appropriately. This leads to better memory utilization and reduced CPU usage.
