Resource Timing limitation - Skipping Androids bellow API level 24 (Android Nougat)

[hare989]

Hi,

There is limitation in Radar.start(int zoneId, int customerId, RadarScheme scheme); interface implementation in RadarWebView.java where is stated that:

if (Build.VERSION.SDK_INT < 24) {
// Resource Timing is probably not available, so let's skip.
// Also skipping HTTPS on versions of Android where TLS might be a problem (<APIv19)
Log.d(TAG, String.format("Skipping on API version %d", Build.VERSION.SDK_INT));
}

Why Resource Timing wouldn't be available on SDK versions bellow 24 since WebView for Android is based on Chromium (which support Resource Timing API) and introduced as such in KITKAT and all above Android versions?
