Your code should not reference the `/sdcard` path directly, which is
platform-dependent. You should use
`Environment.getExternalStorageDirectory().getPath()` instead.

Similarly, do not reference the `/data/data/` path directly, as it can vary in
multi-user scenarios. You should use `Context.getFilesDir().getPath()` instead.

For more information, please see the documentation for
[android.os.Environment](http://developer.android.com/reference/android/os/Environment.html)
and
[android.content.Context](http://developer.android.com/reference/android/content/Context.html).

This check is an adaptation of the `SdCardPath` rule of
[Android Lint](http://tools.android.com/tips/lint-checks).
