LSP server doesn't recognise builtin ParcelFileDescriptor type

[qwandor]

When parsing an AIDL file which refers to a ParcelFileDescriptor, the LSP server gives an error that it is an unknown type. However ParcelFileDescriptor is a builtin type, so it can be used without any import.

e.g.

package test;

parcelable Test {
    ParcelFileDescriptor file;
}
