Android Gets the information about the GSM/CDMA signal of the mobile phone and obtains the base station information _android

How do we get a CDMA or GSM phone signal on Android, where we often easily get a list of WiFi signals?

The system provides the Telephonymanager class, this kind is very rich, basically you need the handset information to be able to obtain, that below to see we need the CDMA and the GSM signal is how obtains.

Private Telephonymanager Telephonymanager;
Private Phonestatelistener Phonestatelistener;

First declare two variables

To initialize a variable in the OnCreate () method

Initphonestatelistener ();
Telephonymanager = (Telephonymanager) this.ctx.getSystemService (Context.telephony_service);
Telephonymanager.listen (Phonestatelistener, phonestatelistener.listen_signal_strengths);
Telephonymanager.listen (phonestatelistener,phonestatelistener.listen_cell_location); if (Telephonymanager.getcelllocation ()!=null) {//Get current base station information phonestatelistener.oncelllocationchanged (
Telephonymanager.getcelllocation ()); /** Initialize Phonestatelistener/private void Initphonestatelistener () {phonestatelistener = new Phonestatelistener () {@O Verride public void oncelllocationchanged (celllocation location) {//TODO auto-generated Method stub if (location Instanc

Gsmcell Gsmcell = new Gsmcell ();
Gsmcell.lac = ((gsmcelllocation) location). Getlac ();
Gsmcell.cid = ((gsmcelllocation) location). Getcid ();
/** get MCC,MNC/String mccmnc=telephonymanager.getnetworkoperator (); if (Mccmnc!=null&&mccmnc.length () >=5) {GSMCELL.MCC = Mccmnc.subString (0, 3);
GSMCELL.MNC = mccmnc.substring (3, 5);
} gsmcell.signal=lastsignal;
Gsmcell.time = System.currenttimemillis (); if (Gsmcell.lac!=-1 && gsmcell.cid!=-1) {gsmcells.add (0, Gsmcell);//Collections.sort (gsmcells);///** Save up to

The above is a small series for everyone to get the Android phone GSM/CDMA signal information, and access to the base station information of the entire content of the method, I hope that we support cloud-Habitat Community ~
