With Python and Pygame being ported to Android, it is in principle possible to use Expyriment on Android devices, however, without OpenGL and extras support. This is achived by compiling Python, Pygame and Expyriment into a Java app, for intance by using PGS4A.
The easiest way to run experiments on Android devices is to install the already available Pydroid3.
Once installed, go to the menu option "Pip", type in "expyriment" as the library name and click "INSTALL". Expyriment scripts can then be opened and run from the main view.
(At first usage, it seems to be necessary to import Pygame once with
import pygame before importing Expyriment).
We also provide the "Expyriment Android Runtime", an Android application which can be used to directly run experiments on an Andoroid device (with Android > 2.2). You can download the current version from our Android release page.
Please note, however, that this is only available for an older version of Expyriment (0.7.0)!
Once installed, the application will look for Expyriment scripts (each in its own subdirectory) in a directory called 'expyriment', located at the root level of either storage device under 'mnt' (i.e. the internal or external SD card). Examples of correctly located Expyriment scripts include:
/mnt/sdcard0/expyriment/exp1/exp1.py /mnt/sdcard0/expyriment/exp2/exp2.py /mnt/extSdCard/expyriment/exp3/exp3.py /mnt/extSdCard/expyriment/exp4/exp4.py
OpenGL not supported
Currently, OpenGL mode is not supported on Android. This will affect the timing
of visual stimuli as blocking on the vertical retrace is not possible (see also
Timing). To run a script without OpenGL mode, expyriment.control.defaults.open_gl needs to be set to 0.
Extras not supported Currently, extras are not supported on Android. This also means that the plugin system is not available.
