So how do you get the raw files from the camera to the phone?
The R-D1 preceded SDHC by years, so it can use no Wifi SDHC cards - and the first generation Eye-Fi, which still was SD, is no real option today (even if it should support the R-D1 regarding power requirements) given its lack of direct connectivity and requirement of a insecure WLAN.
So you'll have to read the card outside the camera - but there is no Android phone with a built-in full size SD slot (nor any way to adapt a card big-into-small inside the usually battery bay internal MicroSD slots).
Easy and universally compatible across phones would be battery driven Wifi media servers with a SDHC slot or USB port, like some of the AirStash or Cloudftp devices - but these are not exactly cheap.
Apart from that, you could use an external reader hooked up through USB OTG - on the very few phones that support the latter. Only Sony has OTG support across most of its smartphones, other makers mostly only have it on a few of the now or once top price models.
There is more choice among OTG capable tablets. But even there you can still run into issues as the OTG support in the system software often is partial (e.g. limited to 3G sticks or audio docking stations) so that you may need extra software to supply the missing drivers. Best bet so far is the Nexus 7, for which software for the very purpose of accessing camera cards exists (Nexus Media Importer), but other tablets or phones (with OTG hardware support) unsupported by the above could get at the card filesystem through Total Commander (with USB plugin), and at the file contents with one of the raw capable photo viewers/editors, or with Raw Decoder.
