① RIL>GSMPhone Call状态变化 -> 发出来电通知
0. Modem发出Call状态变化的通知，
1. framwork/opt/telephony/.../RIL.java
1.1.RIL接收到RIL_UNSOL_RESPONSE_CALL_STATE_CHANGED消息
1.2.然后经由mCallStateRegistrants.notifyRegistrants发出通知（RegistrantList消息处理机制此处不做具体说明）。 private void processUnsolicited ( Parcel p ) { ... switch(response) { ... case RIL_UNSOL_RESPONSE_CALL_STATE_CHANGED: if (RILJ_LOGD) unsljLog(response); mCallStateRegistrants.notifyRegistrants(new AsyncResult(null, null, null));
BaseCommands.java registerForCallStateChanged() mCallStateRegistrants.add(r);
注册为观察者（android源码中大量用到观察者模式，或者叫RegistrantList消息处理机制）。
@Override public void registerForCallStateChanged(Handler h, int what, Object obj) { Registrant r = new Registrant (h, what, obj); //添加到观察者列表
mCallStateRegistrants.add(r); } 2. framwork/opt/telephony/...GSMCallTracker.java
2.1查找察者被调用的地方（AS中的快捷键Ctrl+Alt+H）， 两处被响应处理处理，其中一处：GSMCallTracker handleMessage
...//registerForCallStateChanged调用 mCi.registerForCallStateChanged(this, EVENT_CALL_STATE_CHANGE, null); ... @Override public void //响应处理 handleMessage (Message msg) { ... case EVENT_CALL_STATE_CHANGE: //调用父类CallTracker查询Call List方法 pollCallsWhenSafe ();
break;
2.1.1. pollCallsWhenSafe ()方法在CallTracker.java中实现
protected void pollCallsWhenSafe () {
mNeedsPoll = true; if (checkNoOperationsPending()) { mLastRelevantPoll = obtainMessage(EVENT_POLL_CALLS_RESULT); mCi.getCurrentCalls(mLastRelevantPoll);//RIL.java中的getCurrentCalls方法 } } 2.1.2 回到RIL.java getCurrentCalls 将RIL_REQUEST_GET_CURRENT_CALLS 消息封装成 RILRequest 类型并发送。
@Override public void getCurrentCalls (Message result) { RILRequest rr = RILRequest.obtain(RIL_REQUEST_GET_CURRENT_CALLS, result); if (RILJ_LOGD) riljLog(rr.serialString() + "> " + requestToString(rr.mRequest)); send(rr); } 2.2 RIL.java 有三处接收处理 RIL_REQUEST_GET_CURRENT_CALLS 消息，真正的逻辑处理在processSolicited方法
private RILRequest processSolicited (Parcel p) { ...
case RIL_REQUEST_GET_CURRENT_CALLS: ret = responseCallList(p); break; ...
if (rr.mResult != null) { AsyncResult.forMessage(rr.mResult, null, tr); rr.mResult.sendToTarget();//发出handler消息通知 } 2.3 回到framworks/opt/telephony/.../telephony/gsm/GSMCallTracker.java
rr . mResult . sendToTarget ()发出handler消息通知后，会在CallTracker中的handleMessage方法中响应。并且它的消息类型是“ EVENT_POLL_CALLS_RESULT"
@Override public void handleMessage (Message msg) { ... case EVENT_POLL_CALLS_RESULT: ar = (AsyncResult)msg.obj; if (msg == mLastRelevantPoll) { if (DBG_POLL) log( "handle EVENT_POLL_CALL_RESULT: set needsPoll=F"); mNeedsPoll = false; mLastRelevantPoll = null; handlePollCalls((AsyncResult)msg.obj); } break; handlePollCalls方法根据RIL发出的Call List对象判断Call的状态，并发出不同的通知，
1） 新来电的通知是： phone. notifyNewRingingConnection;
handlePollCalls（）{ ...
if (newRinging != null) { mPhone.notifyNewRingingConnection(newRinging); } 另外两个是
2) 通话断开通知 onDisconnected；
3) Call状态变化通知 phone.notifiyPreciseCallStateChanged.
来电的时候发出的是phone.notifyNewRingConnection通知，进入到notifyNewRingConnection方法
3. framworks/opt/telephony/.../telephony/gsm/GSMPhone.java
public void notifyNewRingingConnection(Connection c) { super.notifyNewRingingConnectionP(c); } 调用父类 PhoneBase.java
notifyNewRingingConnectionP() 发出来电通知 mNewRingingConnectionRegistrants.notifyRegistrants(ar);
/** * Notify registrants of a new ringing Connection. * Subclasses of Phone probably want to replace this with a * version scoped to their packages */ public void notifyNewRingingConnectionP(Connection cn) { if (!mIsVoiceCapable) return; AsyncResult ar = new AsyncResult(null, cn, null); mNewRingingConnectionRegistrants.notifyRegistrants(ar); } RegistrantList.java
public /*synchronized*/ void notifyRegistrants(AsyncResult ar) { internalNotifyRegistrants(ar.result, ar.exception); } private synchronized void internalNotifyRegistrants (Object result, Throwable exception) { for (int i = 0, s = registrants.size(); i < s ; i++) { Registrant r = (Registrant) registrants.get(i); r.internalNotifyRegistrant(result, exception); } } /*package*/ void internalNotifyRegistrant (Object result, Throwable exception) { Handler h = getHandler(); if (h == null) { clear(); } else { Message msg = Message.obtain(); msg.what = what; msg.obj = new AsyncResult(userObj, result, exception); h.sendMessage(msg); } } 注册为观察者的方法为：
// Inherited documentation suffices. @Override public void registerForNewRingingConnection( Handler h, int what, Object obj) { checkCorrectThread(h); mNewRingingConnectionRegistrants.addUnique(h, what, obj); } registerForNewRingingConnection这个方法在4个地方被调用，即有4个地方关心是否有新来电的变化。
1.packages/servicesTelephony/.../PstnIncomingCallNotifier.java log： D/Telephony( 1396): PstnIncomingCallNotifier: handleNewRingingConnection
2.framworks/opt/telephony/.../PhoneProxy.java
3.framworks/opt/telephony/test/.../GSMPhoneTEST.java
4.framworks/opt/telephony/.../telephony/CallManager.java 5.0之前是这里处理，新版本由PstnIncomingCallNotifier处理
----------------
前面：RIL发出Call状态变化消息通知，GSMPhone发出来电通知
----------------
Telephony
4. packages/services/Telephony/.../PstnIncomingCallNotifier.java
registerForNotifications方法调用 registerForNewRingingConnection
4.1 调用 Phonebase中 不同的方法，注册为观察者。
翻译（不通顺 =_=）：
我们应当直接跟phoneProxy做交互处理。然而phoneProxy直接与CallManager交互处理， 我们要么监听callmanager，要么就像这样参与到proxy中去。
两种都是不可取的，如果这个类和callmanager能够 register generically with the phone proxy instead ，这会比较好。
或者更好的是只是直接注册通知with phone proxy， 而不用担心技术的改变，这需要改变opt/telephony中的代码。 /** * Register for notifications from the base phone. * TODO: We should only need to interact with the phoneproxy directly. However, * since the phoneproxy only interacts directly with CallManager we either listen to callmanager * or we have to poke into the proxy like this. Neither is desirable. It would be better if * this class and callManager could register generically with the phone proxy instead and get * radio techonology changes directly. Or better yet, just register for the notifications * directly with phone proxy and never worry about the technology changes. This requires a * change in opt/telephony code. */ private void registerForNotifications() { Phone newPhone = mPhoneProxy.getActivePhone(); if (newPhone != mPhoneBase) { unregisterForNotifications(); if (newPhone != null) { Log.i(this, "Registering: %s", newPhone); mPhoneBase = newPhone; //调用 registerForNewRingingConnection方法 mPhoneBase.registerForNewRingingConnection( mHandler, EVENT_NEW_RINGING_CONNECTION, null); mPhoneBase.registerForCallWaiting( mHandler, EVENT_CDMA_CALL_WAITING, null); mPhoneBase.registerForUnknownConnection(mHandler, EVENT_UNKNOWN_CONNECTION, null); } } } 4.2 handle 处理EVENT_NEW_RINGING_CONNECTION消息
private final Handler mHandler = new Handler() { @Override public void handleMessage(Message msg) { ... case EVENT_NEW_RINGING_CONNECTION : handleNewRingingConnection((AsyncResult) msg.obj); break; 4.2.1 handleNewRingingConnection方法，处理新的来电连接。
此处对应的log为：
D/Telephony( 1396): PstnIncomingCallNotifier: handleNewRingingConnection
/** * Verifies the incoming call and triggers sending the incoming-call intent to Telecom. * * @param asyncResult The result object from the new ringing event. */ private void handleNewRingingConnection(AsyncResult asyncResult) { Log.d(this, "handleNewRingingConnection"); Connection connection = (Connection) asyncResult.result; if (connection != null) { Call call = connection.getCall(); // Final verification of the ringing state before sending the intent to Telecom. //在发送intent到Telecom之前最后一次验证ringing 状态 if (call != null && call.getState().isRinging()) { sendIncomingCallIntent(connection); } } } 4.2.2 sendIncomingCallIntent方法
发送incoming call intent到telecom，发送的Connection 类型，里面包括isIncoming getState isRinging等
/** * Sends the incoming call intent to telecom. */ private void sendIncomingCallIntent(Connection connection) { Bundle extras = null; if (connection.getNumberPresentation() == TelecomManager.PRESENTATION_ALLOWED && !TextUtils.isEmpty(connection.getAddress())) { extras = new Bundle(); Uri uri = Uri.fromParts(PhoneAccount.SCHEME_TEL, connection.getAddress(), null); extras.putParcelable(TelephonyManager.EXTRA_INCOMING_NUMBER, uri); } TelecomManager.from(mPhoneProxy.getContext()).addNewIncomingCall( TelecomAccountRegistry.makePstnPhoneAccountHandle(mPhoneProxy), extras); } addNewIncomingCall()定义在： framworks/base/ telecomm /java/android/telecom/ TelecomManager.java
TelecomManager的功能则主要是对TelecomService提供的远程接口的封装，然后提供给应用使用。
addNewIncomingCall方法 @SystemApi
来电时触发此方法
/** * Registers a new incoming call. A {@link ConnectionService} should invoke this method when it * has an incoming call. The specified {@link PhoneAccountHandle？_？} must have been registered * with {@link #registerPhoneAccount}. Once invoked, this method will cause the system to bind * to the {@link ConnectionService} associated with the {@link PhoneAccountHandle} and request * additional information about the call (See * {@link ConnectionService#onCreateIncomingConnection}) before starting the incoming call UI. * * @param phoneAccount A {@link PhoneAccountHandle} registered with * {@link #registerPhoneAccount}. * @param extras A bundle that will be passed through to * {@link ConnectionService#onCreateIncomingConnection}. * @hide */ @SystemApi public void addNewIncomingCall(PhoneAccountHandle phoneAccount, Bundle extras) { try { if (isServiceConnected()) { getTelecomService().addNewIncomingCall( phoneAccount, extras == null ? new Bundle() : extras); } } catch (RemoteException e) { Log.e(TAG, "RemoteException adding a new incoming call: " + phoneAccount, e); } } addNewIncomingCall 的具体实现
Telecomm
5. packages/services/Telecomm/src/com/android/server/telecom/TelecomServiceImpl.java
继承自ITelecomService，TelecomService的接口由TeleComManager封装，并其供给应用使用，
5.1
@Override
addNewIncomingCall
新建intent 设定intent 的ACTION 、addFalgs等
public static final String ACTION_INCOMING_CALL = "android.telecom.action.INCOMING_CALL";
...
/**

6. packages/services/Telecomm/src/com/android/server/telecom/ CallActivity.java
6.1 执行完processIntent()后就finish()，对应的log
D/Telecom ( 1376): CallActivity: onCreate: end
public class CallActivity extends Activity { @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); // TODO: Figure out if there is something to restore from bundle. // See OutgoingCallBroadcaster in services/Telephony for more. processIntent(getIntent()); // This activity does not have associated UI, so close. finish(); Log.d(this, "onCreate: end"); } 6.1.1 processIntent 判断action
/** * Processes intents sent to the activity. * * @param intent The intent. */ private void processIntent(Intent intent) { // Ensure call intents are not processed on devices that are not capable of calling. if (!isVoiceCapable()) { return; } verifyCallAction(intent); String action = intent.getAction(); if (Intent.ACTION_CALL.equals(action) || Intent.ACTION_CALL_PRIVILEGED.equals(action) || Intent.ACTION_CALL_EMERGENCY.equals(action)) { processOutgoingCallIntent(intent); } else if (TelecomManager.ACTION_INCOMING_CALL.equals(action)) { processIncomingCallIntent(intent); } } 6.1.2 processIncomingCallIntent 判断是否是是设备持有者
private void processIncomingCallIntent(Intent intent) { if (UserHandle.myUserId() == UserHandle.USER_OWNER) { CallReceiver . processIncomingCallIntent ( intent );
} else { sendBroadcastToReceiver(intent, true /* isIncoming */); } } 7.1 对应log

1.创建通知
createIncomingCallNotification
private void createIncomingCallNotification( Call call, int state, Notification.Builder builder) { if (state == Call.State.ACTIVE) { builder.setUsesChronometer(true); builder.setWhen(call.getConnectTimeMillis()); } else { builder.setUsesChronometer(false); } // Add hang up option for any active calls (active | onhold), outgoing calls (dialing). if (state == Call.State.ACTIVE || state == Call.State.ONHOLD || Call.State.isDialing(state)) { addHangupAction(builder); } else if (state == Call.State.INCOMING || state == Call.State.CALL_WAITING) { addDismissAction(builder); if (call.isVideoCall(mContext)) { addVoiceAction(builder); addVideoCallAction(builder); } else { addAnswerAction(builder); } } } 上面添加“接听”和“忽略”两个操作，
private void addAnswerAction(Notification.Builder builder) { Log.i(this, "Will show \"answer\" action in the incoming call Notification"); PendingIntent answerVoicePendingIntent = createNotificationPendingIntent( mContext, InCallApp.ACTION_ANSWER_VOICE_INCOMING_CALL); builder.addAction(R.drawable.ic_call_white_24dp, mContext.getText(R.string.description_target_answer), answerVoicePendingIntent); } private void addDismissAction(Notification.Builder builder) { Log.i(this, "Will show \"dismiss\" action in the incoming call Notification"); PendingIntent declinePendingIntent = createNotificationPendingIntent(mContext, InCallApp.ACTION_DECLINE_INCOMING_CALL); builder.addAction(R.drawable.ic_close_dk, mContext.getText(R.string.notification_action_dismiss), declinePendingIntent); } 启动通知了：
NotificationManager.java
/** * Post a notification to be shown in the status bar. If a notification with * the same id has already been posted by your application and has not yet been canceled, it * will be replaced by the updated information. * * @param id An identifier for this notification unique within your * application. * @param notification A {@link Notification} object describing what to show the user. Must not * be null. */ public void notify(int id, Notification notification) { notify(null, id, notification); } 根据下面的说明我们知道，在状态栏显示处通知
我们跟的是来电的代码，来电信息呈献给用户有两种情况：
1. 屏幕唤醒状态下 是在通知栏显示通知
2. 屏幕熄灭状态下 点亮屏幕全屏显示
==2015-05-06修改==
上面的描述不准确，评论区也有同学指出，在非熄屏但锁屏的情况下，来电也是全屏的。
这一部分的东西确实我没有理清楚，后面有时间我会搞清楚再更新这一部分的内容。
