I define tmpDir like "C:\temp" or /tmp
Droidium creates a temp directory like C:\temp-1223-1454-1245-12545
I expect directory to be rather C:\temp\1223-1454-1245-12545
Current behavior is problematic as it requires user to be slash aware as otherwise he might want to create a directory in tree hierarchy where elevated permissions are needed.
new File(File parent, String childPath) would be the best way how to handle this.
