I am making modifications in a previous project, which is basically developed for kids and teenagers. It blocks text messaging, emails, calls and internet when a user drives at speed greater than 16 MPH. The service is activated through SMS. Modification is required as the app doesn't works on Android v4.1<http://developer.android.com/about/versions/jelly-bean.html>and above. I have seen an app on PlayStore named Safely Go<https://play.google.com/store/apps/details?id=com.safely.go.driver.safety.stop.texting.driving&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5zYWZlbHkuZ28uZHJpdmVyLnNhZmV0eS5zdG9wLnRleHRpbmcuZHJpdmluZyJd>. This app has a button on click of which, status changes to driving. In this mode, if a user clicks on dialer, messaging, settings or browser, their own activity opens up, instead of default behavior. In short, in this mode a user cannot access anything except those applications, which the user has chosen to use during driving.
As per my requirement, the service will be activated through SMS. Once service gets activated, and user's speed reaches more than 16 MPH, I want that when user clicks on Dialer, my activity should open which will show a warning message, instead of opening dial pad. I am not getting how can I accomplish this feature. As a service has no direct interaction with user, so the android system cannot catch key event in service. I was thinking of using BroadcastReceiver<http://developer.android.com/reference/android/content/BroadcastReceiver.html>, but it is not clear to me how a keyevent will be broadcast when user touches dialer icon. May be I am wrong, but AFAIK, an activity cannot catch KEYCODE_CALL<http://developer.android.com/reference/android/view/KeyEvent.html#KEYCODE_CALL>. Or, am I moving in wrong direction? I simply want to know how can I override default behavior dialer. If someone has any information please share, as it would be of great help for me. -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
