Android OS 6.0 devices Typeface.createFromFile with joypixels 6.6/7.0 version emoji font failed

`try{
mEmoji = Typeface.createFromFile(ttfPath);
}catch (Exception e){
if(BuildConfig.LOG_ENABLE){
Log.e(TAG , e ,"parseConfigFile failed ");
}
}`

When I run this code on Android OS 6.0 devices with the latest version 6.6/7.0 joypixels emoji font, it will throw exceptions "Font not found", but on Android OS version >= 7 devices, it worked well. And if I use joypixels 3.0 version font, it also worked well on Android 6.0.
