Is there a mechanism for observing changes in system properties from your own app in Android SDK?
For example, I want to be able to detect changes in the system.adb.tcp.port
property.
I don't think exist a mechanism to do this., but you may be able to retrieve system properties by executing getprop in a Process and retrieve its output.
or try this link : [for System.getProperty()] http://developer.android.com/reference/java/lang/System.html#getProperty%28java.lang.String,%20java.lang.String%29
