android - Instant signal strength -

i need find way measure current signal strength of android phone, without need register phonestatelistener god knows when returns actual asu.

something like:

int signal = getphonesignal(); 

any plz?

thanks!

if have closer on android sources see after registering phonestatelistener have instant notification:

public void listen(phonestatelistener listener, int events) {         string pkgfordebug = mcontext != null ? mcontext.getpackagename() : "<unknown>";         try {             boolean notifynow = (getitelephony() != null);             mregistry.listen(pkgfordebug, listener.callback, events, notifynow);         } catch (remoteexception ex) {             // system process dead         }     } 

so can create own timer , on timer update register new listener , after receiving instant update remove passing same listener object , set events argument listen_none.

of course can't call best practice alternative can see calculate signal strength based on signal strengths getneighboringcellinfo().

p.s. not god knows when phonestatelistener triggered ;)
