What approach should I prefer? I want my solution to work on android 4.2 upwards, also in L and M.

getRecentTasks - won't work in android L anymore...
AccessibilityService - I monitor the active apps myself and so I can show a list of recent apps, always, without quering any android resource.
UsageStatsManager - I query the manager everytime I need infos and so I can show the recent apps

Question

Which approach is better than the other? Especially, concerning energy consumption? I don't want my app to consume more battery than necessary...
Does anyone know an alternative solution? Or even a better one?

Currently I decided to use the AccessibilityService, as I read, that the UsageStatsManager can be quite slow if I query a long period and my app would always query the total up time period...

have you got the getRecentTask with this code? – Ankit Sharma Dec 10 '15 at 07:04
Sorry, I'm not sure what you want to know... I tried using `getRecentTasks` in phones with android < 5 but it can't be used afterwards anymore. There I use the `Accessibilityservice`.... – prom85 Dec 10 '15 at 07:06
