-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello,
Here is some more background info on why the app needs updated and what I think is the main functionality required. The original app was designed for Android 18 although there are now various SDK levels mentioned in various manifest files. Minimal testing on other API levels was done, pretty much just the developers phone. Targeting as low an SDK version as possible would be desirable. Obviously not way back to Android 2 but something which allows a reasonable percentage of devices to use the app (http://developer.android.com/about/dashboards/index.html). 4.1 (SDK 16) may be a good target. The app uses various dependencies, listed in the build files. However, these dependencies may be out of date and in fact may be unused by the code. They need to be cleaned up. The original app used a modified version of the apache http libraries to talk to the taverna server code because the android sdk did not include an up to date version and the latest versions clashed with the android package namespaces. Android compatible versions of recent versions of the apache http libaries are now available (https://hc.apache.org/httpcomponents-client-4.3.x/android-port.html) and I tried to use them in my 'fork' although testing was minimal. The mygrid taverna server library (https://github.com/myGrid/t2-server-jar) is used to access the taverna server API. This library is not actively supported and in fact may be too heavyweight for the app. It is not even clear what branch is used. The taverna server API is just a REST based API over HTTP (http://dev.mygrid.org.uk/wiki/display/tav250/REST+API) so some refactoring is a good idea. It has to be able to handle talking to a taverna server over HTTPS with a username/password that is not the default taverna/taverna one. The HTTPS may have a user created certificate which is not from a CA. Some of the UI relies on the sliding menu library by Jeremy Feinsten which is included directly in the src rather than via gradle. The provenance of the code is unclear, possible from https://github.com/jfeinstein10/SlidingMenu. There may be a more modern Android way to do that kind of UI design but I am not convinced that the app needs it. The PullToRefresh library by Chris Baines (possibly https://github.com/chrisbanes/Android-PullToRefresh) is used via gradle but again there may be a modern Android way to do things. One of the important tasks is to ensure that the app can be supported beyond the project end and that means relying on 3rd party libs that are actively supported. Think of the current app as a demonstrator. I would be happy for the it to be developed from scratch. There is no need for it to even be an Android app, a web app would be just as good as long as the functionality is there. In fact, that is a good way to target multiple mobile platforms perhaps using some apache cordova (http://cordova.apache.org/) for any native functionality required. The basic app functionality required (not an exhaustive list): View workflows from http://www.myexperiment.org Log in to http://www.myexperiment.org and view your workflows Talk to required parts of taverna server API over HTTPS. Run a workflow. Requires upload of input data and the workflow to a taverna server instance. Monitor workflow run. View workflow run results. Download results.
