I’ve started working on it! Currently the widget is standalone and can be displayed, but the data is missing. This is because previously the Launcher collected the necessary information (e.g. every time a app was started, the Fairphone Launcher stored that information to calculate usage stats).
To make it work without the Fairphone Launcher, I will use the Android UsageStatsManager. This, however, needs special permissions from the user while adding the widget and requires us to use API level 21 (Android 5.0 and above).
I will probably need a few weeks until this works well. In the meantime, I will send you PM’s with beta versions you can test. If anyone else is interested in testing the MyApps widget, just drop me a message.
