Vals for check external storage readable/writable

[illuzor]

I would like to propose two useful vals:

val isExternalStorageWritable
    get() = Environment.MEDIA_MOUNTED == Environment.getExternalStorageState()

val isExternalStorageReadable
    get() = Environment.MEDIA_MOUNTED_READ_ONLY == Environment.getExternalStorageState() || externalStorageWritable

But I don`t know where to add them. I mean which file. Maybe create a new one?

• Firstly, I would prefer extensions on Environment class instead of declaring top-level vals (visible everywhere).
• Then I would add inline modifier to both properties, create KEnvironment.kt file and put vals inside.
