Getting java.lang.NoSuchMethodError: android.os.FileUtils.getFatVolumeId in 4.2.2 and later OS

Question

I am facing issue in service onCreate() when trying to get SD Card id. Using FileUtils class of android.os package from src-external/android-core.

mCardId =
  FileUtils.getFatVolumeId(Environment.getExternalStorageDirectory().getPath());

Crash Log :

Answer 1

FileUtils is a platform-internal class, annotated with @hide. You should not be using it.

Thanks for quick response, i am using it and working fine but issue is only from 4.2.2 and later devices. – Elide

@BipinVayalu: At most, it is "working fine" on the devices you have tried. There is no requirement that any device have FileUtils, let alone any specific method on it. And, as you are discovering, there is no requirement for Google to continue offering it. – Gipson
