ExoPlayer, how to load bigger parts of remote audio files

Answer of @Massimo is correct but the way is deprecated

use something like this

DefaultLoadControl.Builder()
            .setBufferDurationsMs(
                DefaultLoadControl.DEFAULT_MIN_BUFFER_MS, 
                30_000, 
                DefaultLoadControl.DEFAULT_BUFFER_FOR_PLAYBACK_MS,
                DefaultLoadControl.DEFAULT_BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS
            )

I've found the solution. Since I'm not finding other related questions, I'll answer to my question (I hope someone will need it in the future):

The right object to configure is the LoadControl passed to the ExoPlayerFactory when creating the ExoPlayer object:

Original answer (deprecated):

val loadControl = DefaultLoadControl(
            DefaultAllocator(true, C.DEFAULT_BUFFER_SEGMENT_SIZE),
            5 * 60 * 1000, // this is it!
            10 * 60 * 1000,
            DefaultLoadControl.DEFAULT_BUFFER_FOR_PLAYBACK_MS.toLong(),
            DefaultLoadControl.DEFAULT_BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS.toLong()
)
exoPlayer = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl)

The updated answer:

val bandwidthMeter = DefaultBandwidthMeter.Builder(context).build()
val trackSelectionFactory = AdaptiveTrackSelection.Factory()
val trackSelector = DefaultTrackSelector(trackSelectionFactory)

val loadControl = DefaultLoadControl.Builder()
        .setAllocator(DefaultAllocator(true, C.DEFAULT_BUFFER_SEGMENT_SIZE))
        .setBufferDurationsMs(
            5 * 60 * 1000, // this is it!
            10 * 60 * 1000,
            DefaultLoadControl.DEFAULT_BUFFER_FOR_PLAYBACK_MS,
            DefaultLoadControl.DEFAULT_BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS
        )
        .setTargetBufferBytes(DefaultLoadControl.DEFAULT_TARGET_BUFFER_BYTES)
        .setPrioritizeTimeOverSizeThresholds(DefaultLoadControl.DEFAULT_PRIORITIZE_TIME_OVER_SIZE_THRESHOLDS)
        .createDefaultLoadControl()

exoPlayer = ExoPlayerFactory.newSimpleInstance(
        context,
        DefaultRenderersFactory(context),
        trackSelector,
        loadControl,
        null,
        bandwidthMeter)
