OS: Android 8.1
需求分析
1、禁止系统来电铃声，提供接口给客户自己播放铃声
2、禁止系统拉起来去电页面(InCallActivity),消息通知客户拉起自己的来去电页面
3、禁止来电消息 Notification 显示(包括未接来电)，点击跳转至 InCallActivity(未接来电消息可通知客户或者将 PendingIntent 改成客户的)
上代码
1、系统来电铃声播放在 Telecomm 应用中，我们发现一般都是先听到铃声才看到 UI 被拉起，那是因为铃声在 Telecomm 中，UI 需要通过 InCallService 通知到 Dialer 中。
vendor\mediatek\proprietary\packages\services\Telecomm\src\com\android\server\telecom\Ringer.java
public boolean startRinging(Call foregroundCall, boolean isHfpDeviceAttached) {
//cczhegn add return for customer self control ringing, system ignore
if (true) {
return ;
}
if (foregroundCall == null) {
/// M: ALPS03787956 Fix wtf log warning. @{
/// Hand up the call immediately when ringing. Then the foreground call will
/// change to null, but call audio is start ringing at the same time.
/// Log.wtf will occur in this case.
/// Solution:
/// Call audio can handle this case, so change Log.wtf to Log.i here.
Log.i(this, "startRinging called with null foreground call.");
/// @}
return false;
}
AudioManager audioManager =
(AudioManager) mContext.getSystemService(Context.AUDIO_SERVICE);
boolean isVolumeOverZero = audioManager.getStreamVolume(AudioManager.STREAM_RING) > 0;
boolean shouldRingForContact = shouldRingForContact(foregroundCall.getContactUri());
boolean isRingtonePresent = !(mRingtoneFactory.getRingtone(foregroundCall) == null);
boolean isSelfManaged = foregroundCall.isSelfManaged();
....
}
public void stopRinging() {
//cczheng add return for customer self control ringing, system ignore
if (true) {
return ;
}
if (mRingingCall != null) {
Log.addEvent(mRingingCall, LogUtils.Events.STOP_RINGER);
mRingingCall = null;
}
if (mIsVibrating) {
Log.addEvent(mVibratingCall, LogUtils.Events.STOP_VIBRATOR);
mVibrator.cancel();
mIsVibrating = false;
mVibratingCall = null;
}
}
只需要将 startRinging() 和 stopRinging() 直接 return 即可，系统就不会响铃了。
2、提供播放铃声工具类 RingUtil 给客户
public class RingUtil {
private static final String TAG = "RingUtil";
private static Ringtone ringtone;
private static Ringtone getRing(Context context){
if (null == ringtone){
Uri defaultRingtoneUri = RingtoneManager.getActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE);
ringtone = RingtoneManager.getRingtone(context, defaultRingtoneUri);
}
return ringtone;
}
public static void startRing(Context context){
getRing(context);
if (!ringtone.isPlaying()){
ringtone.play();
}
}
public static void stopRing(Context context){
getRing(context);
if (ringtone.isPlaying()){
ringtone.stop();
}
}
}
3、禁止系统拉起来去电页面
刚刚上面说到 Telecom 和 Dialer 主要通过 InCallService 通信，重要的两个方法 onCallAdded、onCallRemoved，从字面意思很容易理解，当 call 加入和移除时回调。
InCallPresenter 可以说是 Call 的管理中心，来电去电都经过这处理，所以我们在此处修改比较容易
vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\incallui\InCallPresenter.java
//来电拉起 InCallActivity 的地方
public void showInCall(boolean showDialpad, boolean newOutgoingCall) {
LogUtil.d("InCallPresenter.showInCall", "Showing InCallActivity");
//cczheng annotaion don't show sysytem InCallActivity
//mContext.startActivity(
//InCallActivity.getIntent(
//mContext, showDialpad, newOutgoingCall, false /* forFullScreen */));
}
//去电拉起 InCallActivity 的地方
public void maybeStartRevealAnimation(Intent intent) {
LogUtil.e("InCallPresenter.OutgoingCall", "maybeStartRevealAnimation");
if (intent == null || mInCallActivity != null) {
return;
}
final Bundle extras = intent.getBundleExtra(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS);
if (extras == null) {
// Incoming call, just show the in-call UI directly.
return;
}
if (extras.containsKey(android.telecom.Call.AVAILABLE_PHONE_ACCOUNTS)) {
// Account selection dialog will show up so don't show the animation.
return;
}
final PhoneAccountHandle accountHandle =
intent.getParcelableExtra(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE);
final Point touchPoint = extras.getParcelable(TouchPointManager.TOUCH_POINT);
InCallPresenter.getInstance().setBoundAndWaitingForOutgoingCall(true, accountHandle);
//cczheng annotaion don't show sysytem InCallActivity
LogUtil.e("InCallPresenter.OutgoingCall", "OutgoingCall is preper start inCallActivity.");
//final Intent activityIntent =
//InCallActivity.getIntent(mContext, false, true, false /* forFullScreen */);
//activityIntent.putExtra(TouchPointManager.TOUCH_POINT, touchPoint);
//mContext.startActivity(activityIntent);
}
4、消息通知客户来去电消息
为了简单我们采用广播的方式，由于 8.1 中静态注册广播有限制，为了突破限制，我们需要在发送广播时加上 intent.addFlags(0x01000000);
vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\incallui\InCallPresenter.java
String number;
public void onCallAdded(final android.telecom.Call call) {
LatencyReport latencyReport = new LatencyReport(call);
if (shouldAttemptBlocking(call)) {
maybeBlockCall(call, latencyReport);
} else {
if (call.getDetails().hasProperty(CallCompat.Details.PROPERTY_IS_EXTERNAL_CALL)) {
mExternalCallList.onCallAdded(call);
} else {
latencyReport.onCallBlockingDone();
mCallList.onCallAdded(mContext, call, latencyReport);
}
}
// Since a call has been added we are no longer waiting for Telecom to send us a call.
setBoundAndWaitingForOutgoingCall(false, null);
call.registerCallback(mCallCallback);
//cczheng add when incall or outcall added notify user can start there incallui
number = TelecomCallUtil.getNumber(call);
if (isOutGoingCall) {
LogUtil.e("InCallPresenter.OutgoingCall", "OutgoingCall number=="+number);
Intent intent = new Intent("com.android.outgoingcall.wireless");
intent.putExtra("outgoingNumber", number);
intent.addFlags(0x01000000);
mContext.sendBroadcast(intent);
}else{
LogUtil.i("InCallPresenter.IncomingCall", "IncomingCall number=="+number);
Intent intentcc = new Intent("com.android.incomingcall.wireless");
intentcc.putExtra("incomingNumber", number);
intentcc.addFlags(0x01000000);
mContext.sendBroadcast(intentcc);
}
}
在 onCallAdded() 方法中，可以看到我们添加了 isOutGoingCall 变量判读是来电还是去电，分别对应不用的 action，通过 TelecomCallUtil 获取当前 call 的 number 顺带发送
5、来去电类型 isOutGoingCall 区分
回到刚刚的屏蔽去电拉起页面的方法 maybeStartRevealAnimation() 中，其中有获取 EXTRA_OUTGOING_CALL_EXTRAS 参数，经过验证确实来电不带此参数，去电带参数
vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\incallui\InCallPresenter.java
//cczheng add for distinguish incall or outgogingcall
private boolean isOutGoingCall;
public void maybeStartRevealAnimation(Intent intent) {
LogUtil.e("InCallPresenter.OutgoingCall", "maybeStartRevealAnimation");
if (intent == null || mInCallActivity != null) {
return;
}
final Bundle extras = intent.getBundleExtra(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS);
if (extras == null) {
// Incoming call, just show the in-call UI directly.
isOutGoingCall = false;//cczheng add for incomingcall
return;
}
if (extras.containsKey(android.telecom.Call.AVAILABLE_PHONE_ACCOUNTS)) {
// Account selection dialog will show up so don't show the animation.
return;
}
final PhoneAccountHandle accountHandle =
intent.getParcelableExtra(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE);
final Point touchPoint = extras.getParcelable(TouchPointManager.TOUCH_POINT);
InCallPresenter.getInstance().setBoundAndWaitingForOutgoingCall(true, accountHandle);
LogUtil.e("InCallPresenter.OutgoingCall", "OutgoingCall is preper start inCallActivity.");
isOutGoingCall = true;//cczhegn add for outgongcall
//final Intent activityIntent =
//InCallActivity.getIntent(mContext, false, true, false /* forFullScreen */);
//activityIntent.putExtra(TouchPointManager.TOUCH_POINT, touchPoint);
//mContext.startActivity(activityIntent);
}
6、禁止来电消息 Notification 显示
vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\incallui\StatusBarNotifier.java
@RequiresPermission(Manifest.permission.READ_PHONE_STATE)
public void updateNotification(CallList callList) {
///cczheng annotaion for don't show incallnotification when pstnoverlayactivity in font
//updateInCallNotification(callList);
}
直接注释 updateInCallNotification()
7、未接来电消息处理
回到 Telecomm 中，MissedCallNotifierImpl 负责管理未接来电消息，如果将 android 自己的 Notification 屏蔽，通知客户自己去显示，略微麻烦，用户需要自己建数据库保存通知已读未读状态，
因为重启需要查询判断是否需要再次显示。这样你可以在 showMissedCallNotification() 中直接发送通知后 return。我们此处采用第二种方式，修改系统 Notification 的 PendingIntent 为客户
vendor\mediatek\proprietary\packages\services\Telecomm\src\com\android\server\telecom\ui\MissedCallNotifierImpl.java
private PendingIntent createCallLogPendingIntent(UserHandle userHandle) {
//cczheng add for jump to customer app
try {
Intent intentc = mContext.getPackageManager().getLaunchIntentForPackage("your customer app packageName");
return PendingIntent.getActivity(mContext, 11, intentc, 0);
}catch (Exception e){
e.printStackTrace();
Intent intent = new Intent(Intent.ACTION_VIEW, null);
intent.setType(Calls.CONTENT_TYPE);
TaskStackBuilder taskStackBuilder = TaskStackBuilder.create(mContext);
taskStackBuilder.addNextIntent(intent);
return taskStackBuilder.getPendingIntent(0, 0, null, userHandle);
}
}
8、按下音量键和电源键静音
系统播放来电铃声时，此时按下音量键或电源键，默认都会停止播放铃声。但这是系统播放铃声的情况下，现在我们已经开发给
客户自己去播放铃声了，所以原来的逻辑就会失效，只能客户自己去停止铃声，但是来电页面响铃中，客户是监听不到音量键或
电源键事件的，只能在系统通知了。
vendor\mediatek\proprietary\packages\services\Telecomm\src\com\android\server\telecom\TelecomServiceImpl.java
@Override
public void silenceRinger(String callingPackage) {
try {
Log.startSession("TSI.sR");
synchronized (mLock) {
enforcePermissionOrPrivilegedDialer(MODIFY_PHONE_STATE, callingPackage);
long token = Binder.clearCallingIdentity();
try {
Log.i(this, "Silence Ringer requested by %s", callingPackage);
//cczheng add for notify custmer press valume/power need silence ringer
mContext.sendBroadcast(new Intent("com.android.key.silence.ringer"));
mCallsManager.getCallAudioManager().silenceRingers();
mCallsManager.getInCallController().silenceRinger();
} finally {
Binder.restoreCallingIdentity(token);
}
}
} finally {
Log.endSession();
}
}
