此篇介绍Android M上的MO流程,并与Android L上做比较。
先看一下Android M整体的一个流程图:
变化主要在流程的前半部分,下面是一张对比图:
AM_AM_compare
变化集中在红色框内。
下面我们开始跟一下MO的流程。
packages/apps/Dialer
以在拨号盘拨号为入口(当然还有很多其他入口,我们就不挨个跟了),DialpadFragment.java handleDialButtonPressed(),这个方法内部的代码变少了,也可以看作是多了一步startCall()
packages/apps/Dialer DialpadFragment.java
private void handleDialButtonPressed() {if (isDigitsEmpty()) { // No number entered.
handleDialButtonClickWithEmptyDigits();
} else {
final String number = mDigits.getText().toString();
// "persist.radio.otaspdial" is a temporary hack needed for one carrier‘s automated
// test equipment.
// TODO: clean it up.
if (number != null
&& !TextUtils.isEmpty(mProhibitedPhoneNumberRegexp)
&& number.matches(mProhibitedPhoneNumberRegexp)) {
Log.i(TAG, "The phone number is prohibited explicitly by a rule.");
if (getActivity() != null) {
DialogFragment dialogFragment = ErrorDialogFragment.newInstance(
R.string.dialog_phone_call_prohibited_message);
dialogFragment.show(getFragmentManager(), "phone_prohibited_dialog");
}
// Clear the digits just in case.
clearDialpad();
} else {
startCall(number, OriginCodes.DIALPAD_DIRECT_DIAL);//这里是新增内容
}
}
}
startCall(),这个方法是新增的,其实也可以看作是拆分出来的
private void startCall(String number, String origin) {
if (mCurrentCallMethodInfo != null && mCurrentCallMethodInfo.mIsInCallProvider &&
!PhoneNumberUtils.isEmergencyNumber(number)) {
mCurrentCallMethodInfo.placeCall(origin, number, getActivity(), false, true,
new StartInCallCallReceiver.InCallCallListener() {
@Override
public void onResult(int resultCode) {
if (resultCode == StatusCodes.StartCall.CALL_CONNECTED) {
hideAndClearDialpad(false);
}
}
});
} else {
// If no sim is selected, or emergency callmethod selected, or number is
// an emergency number, phone account handle should be null, and will use the
// default account.
// Else, create PhoneAccountHandle from selected callmethod components and
// initial call using that account.
PhoneAccountHandle handle = CallMethodInfo.getPhoneAccountHandleFromCallMethodInfo(
getActivity(), mCurrentCallMethodInfo, number);
final Intent intent = IntentUtil.getCallIntent(number,//返回的action:android.intent.action.CALL而在5.1上是android.intent.action.CALL_PRIVILEGED
(getActivity() instanceof DialtactsActivity ?
((DialtactsActivity) getActivity())
.getCallOrigin() : null),
handle);
DialerUtils.startActivityWithErrorToast(getActivity(), intent, origin);//虽然增加了一步startCall,但这里还是调用了方法
hideAndClearDialpad(false);
}
}
注意这里intent的构造,返回值来自 IntentUtil.getCallIntent(),而Android L的则是返回自CallUtil.getCallIntent()。
这俩有啥区别的?最大的不同是他俩返回的ACTION不一样,一个返回的android.intent.action.CALL一个返回android.intent.action.CALL_PRIVILEGED,暂时还没看到有什么明显的影响,不过既然这个action有变化,肯定会对后面的流程有一点影响,后面会提到。
然后另外还有一个CALL_ACTION:android.intent.action.CALL_EMERGENCY,三者在L上的区别与用法见 Android
5.0 上紧急电话EmergencyCall与普通电话MO流程区别
然后两个文件所在的目录不同:IntentUtil位于Dialer,CallUtil位于ContactCommon,
还有就是起初IntentUtil.java叫做PrivilegedCallUtil,然后改名为CallIntentUtil,后又改名为现在的IntentUtil,
再有就是在早起的Android M版本中返回的也是android.intent.action.CALL_PRIVILEGED,后来改成了android.intent.action.CALL,至于原因和提交在这就不深追了(看IntentUtil的提交历史可知)。
DialerUtils.java
public static void startActivityWithErrorToast(Context context, Intent intent, int msgId,
String origin) {
try {
if ((IntentUtil.CALL_ACTION.equals(intent.getAction())
&& context instanceof Activity)) {
// All dialer-initiated calls should pass the touch point to the InCallUI
Point touchPoint = TouchPointManager.getInstance().getPoint();//geiPoint(),对应的setPoint()方法,在点击的时候调用
if (touchPoint.x != 0 || touchPoint.y != 0) {
Bundle extras = new Bundle();
extras.putParcelable(TouchPointManager.TOUCH_POINT, touchPoint);//是与动画有关咯,将传至InCallUI
intent.putExtra(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS, extras);
}
if (origin != null) {
intent.putExtra(PhoneConstants.EXTRA_CALL_ORIGIN, origin);
}
final TelecomManager tm =
(TelecomManager) context.getSystemService(Context.TELECOM_SERVICE);
tm.placeCall(intent.getData(), intent.getExtras());//直接到TelecomManager里去了。在L 5.1上是调用startActivityForResult(),之后再启动CallActivity
} else {
context.startActivity(intent);
}
} catch (ActivityNotFoundException e) {
Toast.makeText(context, msgId, Toast.LENGTH_SHORT).show();
}
}
从下面开始就是主要变化的地方
framework/telecomm
framework/base/telecomm TelecomManager.java
TelecomManager.placeCall是新增的api,
其作用注释里面已经写的很清楚了。
/**
* Places a new outgoing call to the provided address using the system telecom service with
* the specified extras.
*
* This method is equivalent to placing an outgoing call using {@link Intent#ACTION_CALL},
* except that the outgoing call will always be sent via the system telecom service. If
* method-caller is either the user selected default dialer app or preloaded system dialer
* app, then emergency calls will also be allowed.
*
* Requires permission: {@link android.Manifest.permission#CALL_PHONE}
*
* Usage example:
* <pre>
* Uri uri = Uri.fromParts("tel", "12345", null);//Uri 主要是号码
* Bundle extras = new Bundle();
* extras.putBoolean(TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE, true);//默认开扬声器
* telecomManager.placeCall(uri, extras);
* </pre>
*
* The following keys are supported in the supplied extras.
* <ul>
* <li>{@link #EXTRA_OUTGOING_CALL_EXTRAS}</li>
* <li>{@link #EXTRA_PHONE_ACCOUNT_HANDLE}</li>
* <li>{@link #EXTRA_START_CALL_WITH_SPEAKERPHONE}</li>
* <li>{@link #EXTRA_START_CALL_WITH_VIDEO_STATE}</li>
* </ul>
*
* @param address The address to make the call to.
* @param extras Bundle of extras to use with the call.
*/
public void placeCall(Uri address, Bundle extras) {
ITelecomService service = getTelecomService();
if (service != null) {
if (address == null) {//检查号码
Log.w(TAG, "Cannot place call to empty address.");
}
try {
service.placeCall(address, extras == null ? new Bundle() : extras,
mContext.getOpPackageName());
} catch (RemoteException e) {
Log.e(TAG, "Error calling ITelecomService#placeCall", e);
}
}
}
packages/services/Telecomm
TelecomServiceImpl.java placeCall
/**
* @see android.telecom.TelecomManager#placeCall
*/
@Override
public void placeCall(Uri handle, Bundle extras, String callingPackage) {
enforceCallingPackage(callingPackage);
if (!canCallPhone(callingPackage, "placeCall")) {
throw new SecurityException("Package " + callingPackage
+ " is not allowed to place phone calls");
}
// Note: we can still get here for the default/system dialer, even if the Phone
// permission is turned off. This is because the default/system dialer is always
// allowed to attempt to place a call (regardless of permission state), in case//注释还是要看
// it turns out to be an emergency call. If the permission is denied and the
// call is being made to a non-emergency number, the call will be denied later on
// by {@link UserCallIntentProcessor}.
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;
synchronized (mLock) {
final UserHandle userHandle = Binder.getCallingUserHandle();
long token = Binder.clearCallingIdentity();
try {
final Intent intent = new Intent(Intent.ACTION_CALL, handle);
intent.putExtras(extras);
new UserCallIntentProcessor(mContext, userHandle).processIntent(intent,
callingPackage, hasCallAppOp && hasCallPermission);
} finally {
Binder.restoreCallingIdentity(token);
}
}
}
看到UserCallIntentProcessor.java不要又觉得是个新东西,它其实原名CallActivity,就是L版本上那个在onCreate中执行了processIntent()之后直接finish()的没有界面的CallActivity。
另外提一下现在M上有的一个类叫做UserCallActivity.java它的工作其实跟L上的CallActivity是一样的,是一个没有界面的Activity,在AndroidManifest.xml中也配置了过滤的action和别名Activity。
是不是有点晕?L上的CallActivity.java升级到M上改名为UserCallIntentProcessor.java,另外新增一个UserCallActivity.java取代其工作。
好吧这样说的话其实UserCallIntentProcessor.java算个新东西,从内容和功能上来说。
一起改名和移动的的还有:
/**
* Processes intents sent to the activity.
*
* @param intent The intent.
*/
public void processIntent(Intent intent, String callingPackageName,
boolean canCallNonEmergency) {
//略过

这是重写action的方法。主要目的是把CALL_PRIVILEGED的action根据号码类型转换为CALL或者CALL_EMERGENCY,就是转换为普通和紧急号码action类型。
按照Android L上的设计,系统拨号应用intent默认携带android.intent.action.CALL_PRIVILEGED,之后在这个方法内部转换。然而现在默认携带的是android.intent.action.CALL,那么现在这个方法就是废的,从系统拨号应用拨出的紧急号码也不会重写成android.intent.action.CALL_EMERGENCY了,紧急电话的拨打可能会受到一些影响。
/**
* Given a call intent and whether or not the number to dial is an emergency number, rewrite
* the call intent action to an appropriate one.
*
* @param intent Intent to rewrite the action for
* @param isPotentialEmergencyNumber Whether or not the number is potentially an emergency
* number.
*/
private void rewriteCallIntentAction(Intent intent, boolean isPotentialEmergencyNumber) {
String action = intent.getAction();
/* Change CALL_PRIVILEGED into CALL or CALL_EMERGENCY as needed. */注释已经很明确了
if (Intent.ACTION_CALL_PRIVILEGED.equals(action)) {//判断条件是 ACTION_CALL_PRIVILEGED,当前M默认为CALL,所以这个方法基本上也是废的。
if (isPotentialEmergencyNumber) {//紧急号码的话重写成android.intent.action.CALL_EMERGENCY
Log.i(this, "ACTION_CALL_PRIVILEGED is used while the number is a potential"
+ " emergency number. Using ACTION_CALL_EMERGENCY as an action instead.");
action = Intent.ACTION_CALL_EMERGENCY;
} else {
action = Intent.ACTION_CALL;//否则重写成
android.intent.action.CALL}
Log.v(this, " - updating action from CALL_PRIVILEGED to %s", action);
intent.setAction(action);
}
}
好,把前面的稍微总结一下,这个aciton变了,但流程上似乎并没什么影响,callImmediately还是被赋值为true了,至于后面啥影响,还没看出来//
