Fix if no sdcard path will be crashed

[TakumaLee]

If no sdcard or getExternalStorageState() is not MEDIA_MOUNTED or MEDIA_MOUNTED_READ_ONLY, the application will be crashed by storage path, and not use the PredefinedPath.

Hi, are you providing full absolute path to folder ?

If yes, then you want to use builder.skipOverview(true, yourPath)

Hi,

If I use skipOverview, and it will be:
java.lang.SecurityException: Unsupported path /data/user/0/{PackageName}/files/xxx.file

it can select internal storage path, but it will throw this exception.

And this is original use withPredefinedPath method exception:
java.lang.IllegalArgumentException: Invalid path: /sdcard

Actually, this change just avoids throwing the exception. :(
