Background service for launching application prior to launch of another application

Question

I am trying to develop a lock kind of application.

First I am displaying list of all the applications installed in the device, and asks users to choose on which applications lock should be enabled.

After user chooses the app, I need to call a lock screen before opening the application.

For example if user chooses to apply lock on gallery I need to start a my app screen for lock before he enters the gallery.

I was able to list all the installed apps but I am unable to detect when the user selects any other app. I have written a service but I can't able to call my app whenever user selects any other application on the device

I want to know how to call my application whenever user selects any other app, How can I detect that ? Thanks in advance

android will not let you know about it unless you trace the `log` — Mehul Joisar, Dec 05 '13 at 09:28

Follow for my mind. Application start - > Main activity start. You can check, what activity is started. So when activity is start. you can start your service. — Sergey Shustikov, Dec 05 '13 at 09:35
Will it be good to use AIDL or Message service in this context? — Nishanth Kumar, Dec 05 '13 at 09:39
