What is the public API to pass on service name for custom tabs? Sample app uses the following and works as expected but i don't see it in official documentation. (https://developer.android.com/reference/android/support/customtabs/CustomTabsIntent.html)
private static final String EXTRA_CUSTOM_TABS_KEEP_ALIVE =
"android.support.customtabs.extra.KEEP_ALIVE";
Intent keepAliveIntent = new Intent().setClassName(
context.getPackageName(), KeepAliveService.class.getCanonicalName());
intent.putExtra(EXTRA_CUSTOM_TABS_KEEP_ALIVE, keepAliveIntent);
