|
| private static java.io.File[] | mobileFiles(java.lang.String whatStat)Returns the array of two possible File locations for a given
statistic.
// Note that we stat them at runtime to see which is
// available, rather than here, to guard against the files
// coming & going later as modules shut down (e.g. airplane
// mode) and whatnot. The runtime stat() isn't expensive compared
// to the previous charset conversion that happened before we
// were reusing File instances.
