linux - How to calculate when the network card opens a connection on Android -


i trying figure out if there way know when app opens internet connection , wakes network card.

so example, have phone off , decide search http://www.cnn.com

in case, lets imagine no background data going on app, connection idle @ time call website. want know when network card opened connection load page.

i have found no apis this. looking @ telephonymanager has different states of network card (dormant, inout, none, etc), found phone never goes dormant, believe due fast dormancy. have been looking @ linux filesystem files might contain information driver, have found none.

i read nice article att explains mobile networks

ok answer use signalstrength class , phonestatelistener's onsignalstrengthschanged in order measure radio signal. helps detect when connecdtion made. referenced att's aro app:
