本流程图基于MTK平台 Android 7.0，拨打的普通电话，本流程只作为沟通学习使用
整体流程图
流程中部分重点知识
packages-apps目录
- dialer应用的DialpadFragment.onClick中，通过用户输入号码并点击拨号按钮（R.id.dialpad_floating_action_button）发起MO
- 在handleDialButtonPressed方法里面会判断输入框中是否含有号码，然后通过IntentUtil构造一个intent，并通过startActivityWithErrorToast启动intent，这里会判断 mProhibitedPhoneNumberRegexp = getResources().getString(R.string.config_prohibited_phone_number_regexp);`是否含有默认拒绝拨打的号码，如果含有弹出含有“Can\’t call this number”字符串的DialogFragment提示用户。
- 在startActivityWithErrorToast中，会获取当前触摸屏幕的位置信息，并存入intent中，后续启动incallUI的时候可能会使用
Point touchPoint = TouchPointManager.getInstance().getPoint();
if (touchPoint.x != 0 || touchPoint.y != 0) {
Bundle extras;
// Make sure to not accidentally clobber any existing extras
if (intent.hasExtra(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS)) {
extras = intent.getParcelableExtra(
TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS);
} else {
extras = new Bundle();
}
extras.putParcelable(TouchPointManager.TOUCH_POINT, touchPoint);
intent.putExtra(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS, extras);
} - 在TelecomUtil的这个方法中判断是否有权限拨打号码，包括判断是否是默认的dialer，和是否有”android.permission.CALL_PHONE”;这个权限
public static boolean hasCallPhonePermission(Context context) {
return isDefaultDialer(context)
|| hasPermission(context, Manifest.permission.CALL_PHONE);
}
packages-services-Telecomm目录
TelecomServiceImpl.placeCall
- 这里会做一些检查，比如：权限检查和包检查，即使call 的权限是关闭的也会走这里，因为一些特殊的通话，比如：紧急通话，在后面的UserCallIntentProcessor中会把不是紧急号码切权限是关闭的通话给结束。
final boolean hasCallAppOp = mAppOpsManager.noteOp(AppOpsManager.OP_CALL_PHONE,
Binder.getCallingUid(), callingPackage) == AppOpsManager.MODE_ALLOWED;
final boolean hasCallPermission = mContext.checkCallingPermission(CALL_PHONE) ==
PackageManager.PERMISSION_GRANTED;UserCallIntentProcessor
processIntent
public void processIntent(Intent intent, String callingPackageName,
boolean canCallNonEmergency) {
// Ensure call intents are not processed on devices that are not capable of calling.
if (!isVoiceCapable()) {//通过com.android.internal.R.bool.config_voice_capable判断是否支持通话，比如：流量卡就不支持通话，并不会启动incallUI
return;
}
String action = intent.getAction();
if (Intent.ACTION_CALL.equals(action) ||
Intent.ACTION_CALL_PRIVILEGED.equals(action) ||
Intent.ACTION_CALL_EMERGENCY.equals(action)) {
processOutgoingCallIntent(intent, callingPackageName, canCallNonEmergency);
}
}
public static final String ACTION_DIAL = "android.intent.action.DIAL";//普通电话进入dialer界面的拨号盘
public static final String ACTION_CALL = "android.intent.action.CALL";//只能拨打普通电话不能拨打紧急号码，M即以上必须有android.Manifest.permission#CALL_PHONE权限
public static final String ACTION_CALL_EMERGENCY = "android.intent.action.CALL_EMERGENCY"; //只能拨打紧急号码的action
public static final String ACTION_CALL_PRIVILEGED = "android.intent.action.CALL_PRIVILEGED";//可以拨打任意类型电话的actionprocessOutgoingCallIntent
- 判断是正常的通话类型是否是SIP phone
if (!PhoneAccount.SCHEME_VOICEMAIL.equals(scheme)) {
handle = Uri.fromParts(PhoneNumberUtils.isUriNumber(uriString) ?
PhoneAccount.SCHEME_SIP : PhoneAccount.SCHEME_TEL, uriString, null);//构造intent的data
}
public static boolean isUriNumber(String number) {
// Note we allow either "@" or "%40" to indicate a URI, in case
// the passed-in string is URI-escaped. (Neither "@" nor "%40"
// will ever be found in a legal PSTN number.)
return number != null && (number.contains("@") || number.contains("%40"));
}- 判断是否有DISALLOW_OUTGOING_CALLS的限制，如果拨打的是emergency call则忽略这个限制，如果拨打的正常号码且具有这个限制，或者权限没有通过，不允许打正常的电话，则弹出错误的对话框 like：“Only emergency calls are allowed.”or “This application cannot make outgoing calls without the Phone permission.”
- 如果是video_call并且打的是emergency_call则需要将video的状态改成voice来打emergency_call
intent.putExtra(CallIntentProcessor.KEY_IS_PRIVILEGED_DIALER,
isDefaultOrSystemDialer(callingPackageName));//判断是否是默认或者系统的dialer应用，如果是才可以打emergency_callPrimaryCallReceiver
public void onReceive(Context context, Intent intent) {
Log.startSession("PCR.oR");
synchronized (getTelecomSystem().getLock()) {
if (!ExtensionManager.getCallMgrExt()
.shouldPreventVideoCallIfLowBattery(context, intent)) {//如果是video_call的话，判断当前的电量是否处于低电模式，现在默认是返回false，后续会根据不同项目要求做定制
getTelecomSystem().getCallIntentProcessor().processIntent(intent);
}
}
Log.endSession();
}CallIntentProcessor
processOutgoingCallIntent
- 这个方法里面主要还是重新拿出intent里面的数据，并判断当前是否是主要的dialer，是否sip_phone，是否有phone账户，是否是video状态，用哪一张卡打，是否是IMS通话请求，是否是会议通话请求，根据这些判断再重新构造intent的Extras，然后通过前面得到的状态创建一个call，如果是conference的话直接创建链接，如果不是则继续往下执行
if (intent.hasExtra(TelecomUtils.EXTRA_SLOT)) {
int slotId = intent.getIntExtra(TelecomUtils.EXTRA_SLOT, -1);
phoneAccountHandle = TelecomUtils
.getPhoneAccountHandleWithSlotId(context, slotId, phoneAccountHandle);//如果有多张卡的话会拿到重那张卡拨打号码
} // Send to CallsManager to ensure the InCallUI gets kicked off before the broadcast returns
Call call = callsManager
.startOutgoingCall(handle, phoneAccountHandle, clientExtras, initiatingUser);//通过这里来启动incallUINewOutgoingCallIntentBroadcaster
processIntent
- 先判断是否是VoicemailNumber，然后再得到格式化号码包括大小写转换成数字，分隔符的分离，判断是否是潜在的紧急号码，再将action为ACTION_CALL_PRIVILEGED类型的通话变成ACTION_CALL_EMERGENCY或者ACTION_CALL，
* - CALL (intent launched by all third party dialers)
* - CALL_PRIVILEGED (intent launched by system apps e.g. system Dialer, voice Dialer)
* - CALL_EMERGENCY (intent launched by lock screen emergency dialer) 如果是拨打紧急号码的话会直接调用placeOutgoingCall，否则会执行后面的流程发送广播。
boolean isUriNumber = mPhoneNumberUtilsAdapter.isUriNumber(number);//判断通话类型，是否是sip_phone
if (!isUriNumber) {
number = mPhoneNumberUtilsAdapter.convertKeypadLettersToDigits(number);//将号码字符串的字母转换成数字
number = mPhoneNumberUtilsAdapter.stripSeparators(number);//将号码中的分割符分离
}
final boolean isPotentialEmergencyNumber = isPotentialEmergencyNumber(number);//判断是否是潜在的紧急号码
Log.v(this, "isPotentialEmergencyNumber = %s", isPotentialEmergencyNumber);
rewriteCallIntentAction(intent, isPotentialEmergencyNumber);//将ACTION_CALL_PRIVILEGED变成ACTION_CALL_EMERGENCY或者ACTION_CALLCallsManager
placeOutgoingCall
- 这里主要是对CDMA模式的call的广播，然后就是根据一些状态判断speaker的开关，是否是紧急号码的判断，然后就是开始创建链接
CreateConnectionProcessor
attemptNextPhoneAccount
if (mCallResponse != null && attempt != null) {
Log.i(this, "Trying attempt %s", attempt);
PhoneAccountHandle phoneAccount = attempt.connectionManagerPhoneAccount;
mService = mRepository.getService(phoneAccount.getComponentName(),
phoneAccount.getUserHandle());//得到创建链接的service
if (mService == null) {
Log.i(this, "Found no connection service for attempt %s", attempt);
attemptNextPhoneAccount();
} else {
mCall.setConnectionManagerPhoneAccount(attempt.connectionManagerPhoneAccount);//设置phoneaccount的ConnectionManager
mCall.setTargetPhoneAccount(attempt.targetPhoneAccount);
mCall.setConnectionService(mService);//设置service
setTimeoutIfNeeded(mService, attempt);
mService.createConnection(mCall, this);//创建链接
}
} ConnectionServiceWrapper
createConnection
- 通过binder创建链接，如果创建成功，先会判断callid是否为null以应对某些特定情况下链接创建成功前呼叫就已经断开了，这种情况下会打印错误log和DisconnectCause.ERROR的response返回，然后继续往下执行创建链接。

TelephonyConnectionService
onCreateOutgoingConnection
这里会做一系列的判断：
- 拨打号码是否为null，拨打电话的账户是否存在
- 判断是否是ECC重连（紧急号码相关），如果是将voiceemail的通话类型转换成tel，否则判断当前号码是否和*228正则表达式匹配，如果匹配就拒绝此次链接，因为这些特殊的数字用于OTASP,如果不禁用可能将LTE锁定到3G网络下。
- 判断phone是否为null，如果为null并且config_checkSimStateBeforeOutgoingCall值为true就会去检查当前SIM卡的状态，并确定是否弹出PIN码的输入框
- 判断飞行模式是否打开
- 判断如果是拨打紧急号码且当前处于4G only数据链接状态，者取消这次链接
- 判断当前网络是否注册成功
- 判断当前是否是紧急号码并处于isInEcm模式，如果拨打的不是紧急号码，但是当前处于ECM模式，则KEY_ALLOW_NON_EMERGENCY_CALLS_IN_ECM_BOOL这个bool值觉得是否结束当前链接（ECM模式是指紧急呼叫回拨模式，一般GSM网络不支持，CDMA网络支持）
- 对service状态的判断，处理不部分异常信息
- 如果是videocall则判断TTY是否开启，如果开启则断开链接(TTY聋哑人专用模式)
- 链接的初始化，number，video状态这些的配置

通过上面流程的分析，和部分逻辑代码的跟踪，我们可以大致了解整个拨号流程所涉及到的目录和类，大致明白了整个过程中的一些状态判断和逻辑处理，后续还会对incallUI界面的构成和流程中某些细分领域的详细研究。
