Android tracking/blocking app updates and bugfixes (accessibility experience beneficial)

This job is to fix issues and add some features to my app which can be found here: [login to view URL] PLEASE COPY/PASTE URLS BECAUSE JOB SITE MAY REMOVE THE TRAILING SLASH (YOU WILL GET A 404 IF YOU JUST CLICK) Tasks: 1. Fix issue with clock controls not sized properly on some versions of Android (example 6.0.1). Screenshot: [login to view URL] 2. Add feature to read URL from chrome browser (currently just firefox supported via plugin) e.g. [login to view URL] 3. Add feature to close Chrome tab (preferred) or minimize chrome browser (alternative option) if website not allowed. 4. Fix issue with Time Limiter mode - 'used time' not always resetting every hour/day when it should. 5. Fix issue with Launch Limiter mode - 'break time' not always counting down accurately. 6. Website blocking is done currently via firefox browser plugin. This plugin fails to install on some Android devices with this error 'firefox is either not installed or the action was cancelled'. I would like this fixed. 7. App currently uses device admin but its possible to disable this in Android settings (settings\lock screen and security\other security settings\device administrators) and then uninstall. I would like app to detect the attempt to disable device admin and request password from my app before allowing it. I know this is possible as there is another app that does it (I think it's using accessibility service). 8. Fix issue that if limited app already running at start of time interval the app usage will not be recorded. 9. Prevent uninstall of app from Nova Launcher To work on this project you would need to sign a standard NDA.
