1、Android Telephony 模块结构

Android Telephony 模块结构简析
Android Telephony 模块结构简析
Telecom 框架概览

• Dialer.apk： /product/priv-app/Dialer/Dialer.apk、packages/apps/Dialer
• Telecom.apk： /system/priv-app/Telecom/Telecom.apk、packages/service/telecomm
• TeleService.apk： /system/priv-app/TeleService/TeleService.apk、packages/service/telephony
  
  
• framework.jar： frameworks/base/telecomm、frameworks/base/telephony
  
  
• telephony-common.jar： frameworks/opt/telephony
  
  
• vendor.ril-daemon： hardware/ril

2、监听和广播获取通话状态

主要查看 framework.jar 代码

2.1 注册

• 1. PhoneStateListener注册：最终调用TelephonyRegistry.java#listenWithEventList添加到ArrayList<Record> mRecords
     packages/apps/Dialer/java/com/android/incallui/InCallPresenter.java

this.context.getSystemService(TelephonyManager.class).listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

• 2. 广播注册：public static final String ACTION_PHONE_STATE_CHANGED = "android.intent.action.PHONE_STATE";，权限android.permission.READ_PHONE_STATE
     packages/apps/Dialer/java/com/android/dialer/dialpadview/DialpadFragment.java

    if (callStateReceiver == null) {IntentFilter callStateIntentFilter =new IntentFilter(TelephonyManager.ACTION_PHONE_STATE_CHANGED);callStateReceiver = new CallStateReceiver();getActivity().registerReceiver(callStateReceiver, callStateIntentFilter);}
/private class CallStateReceiver extends BroadcastReceiver {/*** Receive call state changes so that we can take down the "dialpad chooser" if the phone* becomes idle while the chooser UI is visible.*/@Overridepublic void onReceive(Context context, Intent intent) {String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);if ((TextUtils.equals(state, TelephonyManager.EXTRA_STATE_IDLE)|| TextUtils.equals(state, TelephonyManager.EXTRA_STATE_OFFHOOK))&& isDialpadChooserVisible()) {// Note there's a race condition in the UI here: the// dialpad chooser could conceivably disappear (on its// own) at the exact moment the user was trying to select// one of the choices, which would be confusing.  (But at// least that's better than leaving the dialpad chooser// onscreen, but useless...)LogUtil.i("CallStateReceiver.onReceive", "hiding dialpad chooser, state: %s", state);showDialpadChooser(false);}}}

2.2 通话状态通知

frameworks/base/services/core/java/com/android/server/TelephonyRegistry.java

    public void notifyCallState(int phoneId, int subId, int state, String incomingNumber) {if (!checkNotifyPermission("notifyCallState()")) {return;}if (VDBG) {log("notifyCallState: subId=" + subId+ " state=" + state + " incomingNumber=" + incomingNumber);}synchronized (mRecords) {if (validatePhoneId(phoneId)) {mCallState[phoneId] = state;mCallIncomingNumber[phoneId] = incomingNumber;for (Record r : mRecords) {if (r.matchTelephonyCallbackEvent(TelephonyCallback.EVENT_LEGACY_CALL_STATE_CHANGED)&& (r.subId == subId)&& (r.subId != SubscriptionManager.DEFAULT_SUBSCRIPTION_ID)) {try {// Only the legacy PhoneStateListener receives the phone number.String incomingNumberOrEmpty = getCallIncomingNumber(r, phoneId);r.callback.onLegacyCallStateChanged(state, incomingNumberOrEmpty);} catch (RemoteException ex) {mRemoveList.add(r.binder);}}if (r.matchTelephonyCallbackEvent(TelephonyCallback.EVENT_CALL_STATE_CHANGED)&& (r.subId == subId)&& (r.subId != SubscriptionManager.DEFAULT_SUBSCRIPTION_ID)) {try {// The phone number is not included in the new call state changed// listener.r.callback.onCallStateChanged(state);} catch (RemoteException ex) {mRemoveList.add(r.binder);}}}}handleRemoveListLocked();}broadcastCallStateChanged(state, incomingNumber, phoneId, subId);}

2.3 通话状态

frameworks/base/telephony/java/android/telephony/TelephonyManager.java

CALL_STATE_IDLE： 处于无电话活动，相当于电话挂断，不过要先有CALL_STATE_OFFHOOK判断
CALL_STATE_RINGING： 电话响铃
CALL_STATE_OFFHOOK： 接听电话

    /*** Device call state: No activity.*/public static final int CALL_STATE_IDLE = 0;/*** Device call state: Ringing. A new call arrived and is*  ringing or waiting. In the latter case, another call is*  already active.*/public static final int CALL_STATE_RINGING = 1;/*** Device call state: Off-hook. At least one call exists* that is dialing, active, or on hold, and no calls are ringing* or waiting.*/public static final int CALL_STATE_OFFHOOK = 2;

3、通知状态流程

frameworks/base/core/java/android/telephony/TelephonyRegistryManager.java
frameworks/base/services/core/java/com/android/server/TelephonyRegistry.java

    public void notifyCallStateForAllSubs(int state, String phoneNumber) {if (!checkNotifyPermission("notifyCallState()")) {return;}if (VDBG) {log("notifyCallStateForAllSubs: state=" + state + " phoneNumber=" + phoneNumber);}synchronized (mRecords) {for (Record r : mRecords) {if (r.matchTelephonyCallbackEvent(TelephonyCallback.EVENT_LEGACY_CALL_STATE_CHANGED)&& (r.subId == SubscriptionManager.DEFAULT_SUBSCRIPTION_ID)) {try {// Ensure the listener has read call log permission; if they do not return// an empty phone number.// This is ONLY for legacy onCallStateChanged in PhoneStateListener.String phoneNumberOrEmpty = r.canReadCallLog() ? phoneNumber : "";r.callback.onLegacyCallStateChanged(state, phoneNumberOrEmpty);} catch (RemoteException ex) {mRemoveList.add(r.binder);}}if (r.matchTelephonyCallbackEvent(TelephonyCallback.EVENT_CALL_STATE_CHANGED)&& (r.subId == SubscriptionManager.DEFAULT_SUBSCRIPTION_ID)) {try {// The new callback does NOT provide the phone number.r.callback.onCallStateChanged(state);} catch (RemoteException ex) {mRemoveList.add(r.binder);}}}handleRemoveListLocked();}// Called only by Telecomm to communicate call state across different phone accounts. So// there is no need to add a valid subId or slotId.broadcastCallStateChanged(state, phoneNumber,SubscriptionManager.INVALID_SIM_SLOT_INDEX,SubscriptionManager.INVALID_SUBSCRIPTION_ID);}public void notifyCallState(int phoneId, int subId, int state, String incomingNumber) {if (!checkNotifyPermission("notifyCallState()")) {return;}if (VDBG) {log("notifyCallState: subId=" + subId+ " state=" + state + " incomingNumber=" + incomingNumber);}synchronized (mRecords) {if (validatePhoneId(phoneId)) {mCallState[phoneId] = state;mCallIncomingNumber[phoneId] = incomingNumber;for (Record r : mRecords) {if (r.matchTelephonyCallbackEvent(TelephonyCallback.EVENT_LEGACY_CALL_STATE_CHANGED)&& (r.subId == subId)&& (r.subId != SubscriptionManager.DEFAULT_SUBSCRIPTION_ID)) {try {// Only the legacy PhoneStateListener receives the phone number.String incomingNumberOrEmpty = getCallIncomingNumber(r, phoneId);r.callback.onLegacyCallStateChanged(state, incomingNumberOrEmpty);} catch (RemoteException ex) {mRemoveList.add(r.binder);}}if (r.matchTelephonyCallbackEvent(TelephonyCallback.EVENT_CALL_STATE_CHANGED)&& (r.subId == subId)&& (r.subId != SubscriptionManager.DEFAULT_SUBSCRIPTION_ID)) {try {// The phone number is not included in the new call state changed// listener.r.callback.onCallStateChanged(state);} catch (RemoteException ex) {mRemoveList.add(r.binder);}}}}handleRemoveListLocked();}broadcastCallStateChanged(state, incomingNumber, phoneId, subId);}
