MediaExtractor.getCachedDuration problem

In my application which has the link https://play.google.com/store/app/details?id=audis.mobile.VRadioRecorderLite.views  on the play store.

I used the function http://developer.android.com/reference/android/media/MediaExtractor.html#getCachedDuration() .

I tested this function on the huawei devices exactly the G Play Mini (Model Number: CHC-U01) and it always returns -1 however on the other devices such as Samsung and LG, it returns different values.
