tracking user interaction Android
<p>I am new in Android and is developing an app which runs in background as service to collect user activity. till now my app is able to get information about Time_Start, Time_End and Name of other app used by user.</p>

<p>I want to improve my app to be able to count how many interactions(like user tap, touch,...) user make while using other app.
any help?
Thanks!</p>
