Android Inbound phone monitoring (incoming call monitoring) turn

Permissions Required:

<uses-permission android:name= "Android.permission.READ_PHONE_STATE"/>

Way one: Receive incoming calls via broadcast

 PackageCom.zhouzijing.android.demo;ImportAndroid.content.BroadcastReceiver;ImportAndroid.content.Context;Importandroid.content.Intent;ImportAndroid.telephony.TelephonyManager;ImportAndroid.util.Log; Public classBroadcastreceivermgrextendsBroadcastreceiver {Private FinalString TAG =Mybroadcastreceiver.tag; @Override Public voidOnReceive (Context context, Intent Intent) {String action=intent.getaction (); LOG.I (TAG,"[Broadcast]" +action); //Incoming Calls        if(Action.equals (mybroadcastreceiver.b_phone_state)) {log.i (TAG,"[Broadcast]phone_state]);        Doreceivephone (context,intent); }    }        /*** Processing of telephone broadcasts. * @paramContext *@paramIntent*/     Public voidDoreceivephone (Context context, Intent Intent) {String PhoneNumber=Intent.getstringextra (Telephonymanager.extra_incoming_number); Telephonymanager Telephony=(Telephonymanager) Context.getsystemservice (Context.telephony_service); intState =telephony.getcallstate (); Switch(state) { Casetelephonymanager.call_state_ringing:log.i (TAG,"[broadcast] waiting to be answered =" +PhoneNumber);  Break;  Casetelephonymanager.call_state_idle:log.i (TAG,"[Broadcast] phone hangs up =" +PhoneNumber);  Break;  Casetelephonymanager.call_state_offhook:log.i (TAG,"[broadcast] in call =" +PhoneNumber);  Break; }    }}

Defining the Actitvity Class

 PackageCom.zhouzijing.android.demo;Importandroid.app.Activity;ImportAndroid.content.Context;Importandroid.content.Intent;ImportAndroid.content.IntentFilter;ImportAndroid.os.Bundle;ImportAndroid.telephony.PhoneStateListener;ImportAndroid.telephony.TelephonyManager;ImportAndroid.util.Log;ImportAndroid.view.View; Public classMybroadcastreceiverextendsActivity { Public Final StaticString TAG = "Mybroadcastreceiver";  Public Final StaticString b_phone_state =telephonymanager.action_phone_state_changed; PrivateBroadcastreceivermgr Mbroadcastreceiver; @Override Public voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);    Setcontentview (R.layout.my_broadcast_receiver); }        //Button 1-registering the broadcast     Public voidRegisterit (View v) {log.i (TAG,"Registerit"); Mbroadcastreceiver=Newbroadcastreceivermgr (); Intentfilter Intentfilter=NewIntentfilter ();        Intentfilter.addaction (b_phone_state);        Intentfilter.setpriority (Integer.max_value);    Registerreceiver (Mbroadcastreceiver, Intentfilter); }        //Button 2-Cancel broadcast     Public voidUnregisterit (View v) {log.i (TAG,"Unregisterit");    Unregisterreceiver (Mbroadcastreceiver); }    }

Way two: Through the listener to achieve

 PackageCom.zhouzijing.android.demo;Importandroid.app.Activity;ImportAndroid.content.Context;Importandroid.content.Intent;ImportAndroid.content.IntentFilter;ImportAndroid.os.Bundle;ImportAndroid.telephony.PhoneStateListener;ImportAndroid.telephony.TelephonyManager;ImportAndroid.util.Log;ImportAndroid.view.View; Public classMybroadcastreceiverextendsActivity { Public Final StaticString TAG = "Mybroadcastreceiver"; @Override Public voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);    Setcontentview (R.layout.my_broadcast_receiver); }        /*** button-Monitor phone *@paramv*/     Public voidCreatephonelistener (View v) {Telephonymanager telephony=(Telephonymanager) Getsystemservice (Context.telephony_service); Telephony.listen (NewOnephonestatelistener (), phonestatelistener.listen_call_state); }        /*** Phone status monitoring. * @authorStephen **/    classOnephonestatelistenerextendsphonestatelistener{@Override Public voidOncallstatechanged (intState , String Incomingnumber) {log.i (TAG,"[Listener] Phone number:" +incomingnumber); Switch(state) { Casetelephonymanager.call_state_ringing:log.i (TAG,[Listener] Waiting to receive phone: "+incomingnumber);  Break;  Casetelephonymanager.call_state_idle:log.i (TAG,"[Listener] phone hangs up:" +incomingnumber);  Break;  Casetelephonymanager.call_state_offhook:log.i (TAG,"[Listener] in call:" +incomingnumber);  Break; }            Super. oncallstatechanged (State, Incomingnumber); }    }            }
