Jmol under Android Operating System (smartphones and tablets)
Jmol Android App
Jmol 12.3 is available in a special version for running in tablets under the Android operating system: Jmol Molecular Visualization Activity, version 1.1, requires Android 2.2 or later. Available for free.
Information and download from the Android Market.
- A nearly full touch-screen implementation of Jmol.
- Includes a variety of preset simple visualization modes.
- Allows for command-line entry of Jmol commands.
- Includes a full range of visualizations for crystals (unit cells, symmetry operators, Miller planes, for example).
- Includes a wide variety of surfaces including Van der Waals surfaces, solvent-accessible surfaces, cavities, and molecular surfaces, and atomic and molecular orbitals.
- Directly accesses the Protein Data Bank (PDB, with over 60 000 biomolecular structures) by keyword or by PDB ID.
- Directly accesses the National Institutes of Health National Cancer Institute (NIH/NCI, with over 40 million structures) using a wide variety of chemical identifiers, including CAS registry numbers, InChI keys, trade names, common names, and IUPAC-format names.
- Files from any other internet-available site that can be read by Jmol may also be loaded.
- Connects to the gyroscope, allowing for initiating of spinning by simply moving the tablet in a natural fashion (see Videos).
This activity is under development. Feedback is much appreciated.
A collection of notes about present or possible support for Jmol under Android:
- Since Android doesn't include the Swing Java class, the pop-up menu, the console and the
promptcommand used for asking for saving files from the signed applet will not work. But other functionality may work.
- Jmol feature request #3128416 with some discussion.
Any and all web pages designed using JSmol in the HTML5 modality will work in Android-based systems, via the web browser (i.e., this is not an app and in general requires a live internet connection). The user experience with the molecular models may however be hindered by
- the screen size design of the page,
- support for tactile systems of the page interface and source code,
- processor power of the device (will affect responsiveness of the JSmol object in the page, i.e. smoothness of rotation),
- download time of the page + JSmol library files,
- need for a live internet connection
More responsive, mobile-friendly pages may be written using the Lightweight JSmol object. Note that this is limited to mol-formatted molecular files and to the basic ball-and-stick rendering.
Dominik Raymann has written a wallpaper for Android devices that uses Jmol to display rotating molecules. You can choose a single favorite one or have it random, as well as whether to display the name of the molecule. Read more at the Android Market page.
