android Telephony学习 --- 第八篇 android7.0 来电UI启动流程
incall发起notification后,由systemui根据当前手机状态,来决定是显示来电界面还是headsup小窗口。
-
package/app/Dialer – InCallPresenter
接着上篇文章,从onIncomingCall开始查看:
@Override
public void onIncomingCall(Call call) {
InCallState newState = startOrFinishUi(InCallState.INCOMING);
for (IncomingCallListener listener : mIncomingCallListeners) {
listener.onIncomingCall(oldState, mInCallState, call);
}
}
关注startOrFinishUi方法,若是满足直接显示UI的条件调用showInCall,直接启动UI;否则调用startUi:
private InCallState startOrFinishUi(InCallState newState) {
if (showCallUi || showAccountPicker || isAutoAnswer) {
showInCall(false /* showDialpad */, !showAccountPicker /* newOutgoingCall */);
} else if (startIncomingCallSequence) {
if (!startUi(newState)) {
return mInCallState;
}
}
}
调用StatusBarNotifier.updateNotification:
private boolean startUi(InCallState inCallState) {
if (isCallWaiting || anyOtherSubActive) {
if (mProximitySensor.isScreenReallyOff() && isActivityStarted()) {
mInCallActivity.finish();
return false;
} else {
showInCall(false, false);
}
} else {
mStatusBarNotifier.updateNotification(inCallState, mCallList);
}
return true;
}
-
package/app/Dialer – StatusBarNotifier
incall发起通知,后续由notification决定是显示小窗口还是来电界面:
private void buildAndSendNotification(Call originalCall, ContactCacheEntry contactInfo) {
Notification.Builder publicBuilder = new Notification.Builder(mContext);
final PendingIntent inCallPendingIntent = createLaunchPendingIntent();
if (notificationType == NOTIFICATION_INCOMING_CALL
&& (!InCallPresenter.getInstance().isShowingInCallUi() ||
(pendingAccountSelectionCall != null))) {
configureFullScreenIntent(builder, inCallPendingIntent, call);
}
Notification notification = builder.build();
mNotificationManager.notify(notificationType, notification);
}
configureFullScreenIntent方法:
private void configureFullScreenIntent(Notification.Builder builder, PendingIntent intent,
Call call) {
// Ok, we actually want to launch the incoming call
// UI at this point (in addition to simply posting a notification
// to the status bar). Setting fullScreenIntent will cause
// the InCallScreen to be launched immediately *unless* the
// current foreground activity is marked as "immersive".
builder.setFullScreenIntent(intent, true);
}
携带intent来启动InCallActivity:
private PendingIntent createLaunchPendingIntent() {
final Intent intent = InCallPresenter.getInstance().getInCallIntent(
false /* showDialpad */, false /* newOutgoingCall */);
// PendingIntent that can be used to launch the InCallActivity. The
// system fires off this intent if the user pulls down the windowshade
// and clicks the notification's expanded view. It's also used to
// launch the InCallActivity immediately when when there's an incoming
// call (see the "fullScreenIntent" field below).
PendingIntent inCallPendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
return inCallPendingIntent;
}
- frameworks/base/core – NotificationManager
public void notifyAsUser(String tag, int id, Notification notification, UserHandle user)
{
INotificationManager service = getService();
try {
service.enqueueNotificationWithTag(pkg, mContext.getOpPackageName(), tag, id,
copy, idOut, user.getIdentifier());
}
}
-
frameworks/base/core – NotificationManagerService
找到INotificationManager aidl实现enqueueNotificationWithTag方法的地方:
private final IBinder mService = new INotificationManager.Stub() {
@Override
public void enqueueNotificationWithTag(String pkg, String opPkg, String tag, int id,
Notification notification, int[] idOut, int userId) throws RemoteException {
enqueueNotificationInternal(pkg, opPkg, Binder.getCallingUid(),
Binder.getCallingPid(), tag, id, notification, idOut, userId);
}
- frameworks/base/packages/SystemUI – BaseStatusBar
private final NotificationListenerService mNotificationListener =
new NotificationListenerService() {
@Override
public void onNotificationPosted(final StatusBarNotification sbn,
final RankingMap rankingMap) {
if (sbn != null) {
mHandler.post(new Runnable() {
@Override
public void run() {
if (isUpdate) {
updateNotification(sbn, rankingMap);
} else {
addNotification(sbn, rankingMap, null /* oldEntry */);
}
}
});
-
frameworks/base/packages/SystemUI – PhoneStatusBar
isHeadsUped决定是显示headsup还是来电界面:
@Override
public void addNotification(StatusBarNotification notification, RankingMap ranking,
Entry oldEntry) {
boolean isHeadsUped = shouldPeek(shadeEntry);
if (isHeadsUped) {
mHeadsUpManager.showNotification(shadeEntry);
setNotificationShown(notification);
}
if (!isHeadsUped && notification.getNotification().fullScreenIntent != null) {
try {
notification.getNotification().fullScreenIntent.send();
shadeEntry.notifyFullScreenIntentLaunched();
}
