【Audio】静音或振动模式下重复来电响铃

news 2025/9/2 11:39:20

一、问题描述

基于 Android 14平台，在静音或振动模式下来电是不会播放铃声的，会存在漏掉来电的情况，需要考虑紧急情况下的重复来电，例如在 10 分钟内来电 4 次，在这种情况下需要响铃来提醒用户。

请添加图片描述

二、问题分析

packages/services/Telecomm 这里主要分析最接近响铃的流程，主要是在 Telecomm 应用中，最主要的是 Ringer 这个类

public boolean startRinging(Call foregroundCall, boolean isHfpDeviceAttached) {boolean deferBlockOnRingingFuture = false;// try-finally to ensure that the block on ringing future is always called.try {if (foregroundCall == null) {Log.wtf(this, "startRinging called with null foreground call.");return false;}if (foregroundCall.getState() != CallState.RINGING&& foregroundCall.getState() != CallState.SIMULATED_RINGING) {// It's possible for bluetooth to connect JUST as a call goes active, which would// mean the call would start ringing again.Log.i(this, "startRinging called for non-ringing foreground callid=%s",foregroundCall.getId());return false;}// Use completable future to establish a timeout, not intent to make these work outside// the main thread asynchronously// TODO: moving these RingerAttributes calculation out of Telecom lock to avoid blockingCompletableFuture<RingerAttributes> ringerAttributesFuture = CompletableFuture.supplyAsync(() -> getRingerAttributes(foregroundCall, isHfpDeviceAttached),new LoggedHandlerExecutor(getHandler(), "R.sR", null));RingerAttributes attributes = null;try {mAttributesLatch = new CountDownLatch(1);attributes = ringerAttributesFuture.get(RINGER_ATTRIBUTES_TIMEOUT, TimeUnit.MILLISECONDS);} catch (ExecutionException | InterruptedException | TimeoutException e) {// Keep attributes as nullLog.i(this, "getAttributes error: " + e);}if (attributes == null) {Log.addEvent(foregroundCall, LogUtils.Events.SKIP_RINGING,"RingerAttributes error");return false;}if (attributes.isEndEarly()) {boolean acquireAudioFocus = attributes.shouldAcquireAudioFocus();if (attributes.letDialerHandleRinging()) {Log.addEvent(foregroundCall, LogUtils.Events.SKIP_RINGING, "Dialer handles");// Dialer will setup a ringtone, provide the audio focus if its audible.acquireAudioFocus |= attributes.isRingerAudible();}if (attributes.isSilentRingingRequested()) {Log.addEvent(foregroundCall, LogUtils.Events.SKIP_RINGING, "Silent ringing "+ "requested");}if (attributes.isWorkProfileInQuietMode()) {Log.addEvent(foregroundCall, LogUtils.Events.SKIP_RINGING,"Work profile in quiet mode");}return acquireAudioFocus;}......mUniRinger.updateCVRSRingingState(foregroundCall, attributes.shouldRingForContact());if (foregroundCall.isCVRSCall()) {// used mDefaultVibrationEffect} else if (attributes.isRingerAudible()) {mUniRinger.setVoiceCVRSVolume(true, 0);mUniRinger.muteCVRSFromSilenceRinger(false);mUniRinger.setCVRSPlaying(false);/* @}*/mRingingCall = foregroundCall;Log.addEvent(foregroundCall, LogUtils.Events.START_RINGER);// Because we wait until a contact info query to complete before processing a// call (for the purposes of direct-to-voicemail), the information about custom// ringtones should be available by the time this code executes. We can safely// request the custom ringtone from the call and expect it to be current.if (shouldApplyRampingRinger) {Log.i(this, "create ramping ringer.");float silencePoint = (float) (RAMPING_RINGER_VIBRATION_DURATION)/ (float) (RAMPING_RINGER_VIBRATION_DURATION + RAMPING_RINGER_DURATION);mVolumeShaperConfig =new VolumeShaper.Configuration.Builder().setDuration(RAMPING_RINGER_VIBRATION_DURATION+ RAMPING_RINGER_DURATION).setCurve(new float[]{0.f, silencePoint + EPSILON/*keep monotonicity*/, 1.f},new float[]{0.f, 0.f, 1.f}).setInterpolatorType(VolumeShaper.Configuration.INTERPOLATOR_TYPE_LINEAR).build();if (mSystemSettingsUtil.isAudioCoupledVibrationForRampingRingerEnabled()) {useCustomVibrationEffect = true;}} else {if (DEBUG_RINGER) {Log.i(this, "Create ringer with custom vibration effect");}// Ramping ringtone is not enabled.useCustomVibrationEffect = true;}} else {Log.addEvent(foregroundCall, LogUtils.Events.SKIP_RINGING,"Inaudible: " + attributes.getInaudibleReason()+ " isVibratorEnabled=" + isVibratorEnabled);if (isVibratorEnabled) {// If ringer is not audible for this call, then the phone is in "Vibrate" mode.// Use haptic-only ringtone or do not play anything.isHapticOnly = true;if (DEBUG_RINGER) {Log.i(this, "Set ringtone as haptic only: " + isHapticOnly);}} else {foregroundCall.setUserMissed(USER_MISSED_NO_VIBRATE);return attributes.shouldAcquireAudioFocus(); // ringer not audible}}......// 初始化播放器/* UNISOC: add for CVRS(customized video ringing signal) @{ */if (foregroundCall.isCVRSCall()) {ringtoneSupplier  = null;Log.i(this, "is CVRS call, skip ringtone play");/* @}*/}else if (isHapticOnly) {if (hapticChannelsMuted) {Log.i(this,"want haptic only ringtone but haptics are muted, skip ringtone play");ringtoneSupplier = null;} else {ringtoneSupplier = mRingtoneFactory::getHapticOnlyRingtone;}} else {ringtoneSupplier = () -> mRingtoneFactory.getRingtone(foregroundCall, mVolumeShaperConfig, finalHapticChannelsMuted);}......// 实际播放位置if (ringtoneSupplier != null) {mRingtonePlayer.play(ringtoneSupplier, afterRingtoneLogic);} else {afterRingtoneLogic.accept(/* ringtone= */ null, /* stopped= */ false);}// shouldAcquireAudioFocus is meant to be true, but that check is deferred to here// because until now is when we actually know if the ringtone loading worked.return attributes.shouldAcquireAudioFocus()|| (!isHapticOnly && attributes.isRingerAudible());......
}

获取播放参数，核心变量是 isRingerAudible 用于是否播放铃声

private RingerAttributes getRingerAttributes(Call call, boolean isHfpDeviceAttached) {mAudioManager = mContext.getSystemService(AudioManager.class);RingerAttributes.Builder builder = new RingerAttributes.Builder();LogUtils.EventTimer timer = new EventTimer();boolean isVolumeOverZero = mAudioManager.getStreamVolume(AudioManager.STREAM_RING) > 0;timer.record("isVolumeOverZero");boolean shouldRingForContact = shouldRingForContact(call);timer.record("shouldRingForContact");boolean isSelfManaged = call.isSelfManaged();timer.record("isSelfManaged");boolean isSilentRingingRequested = call.isSilentRingingRequested();timer.record("isSilentRingRequested");boolean isRingerAudible = isVolumeOverZero && shouldRingForContact;timer.record("isRingerAudible");String inaudibleReason = "";if (!isRingerAudible) {inaudibleReason = String.format("isVolumeOverZero=%s, shouldRingForContact=%s",isVolumeOverZero, shouldRingForContact);}boolean hasExternalRinger = hasExternalRinger(call);timer.record("hasExternalRinger");// Don't do call waiting operations or vibration unless these are false.boolean isTheaterModeOn = mSystemSettingsUtil.isTheaterModeOn(mContext);timer.record("isTheaterModeOn");boolean letDialerHandleRinging = mInCallController.doesConnectedDialerSupportRinging(call.getAssociatedUser());timer.record("letDialerHandleRinging");boolean isWorkProfileInQuietMode =isProfileInQuietMode(call.getAssociatedUser());timer.record("isWorkProfileInQuietMode");Log.i(this, "startRinging timings: " + timer);boolean endEarly = isTheaterModeOn || letDialerHandleRinging || isSelfManaged ||hasExternalRinger || isSilentRingingRequested || isWorkProfileInQuietMode;if (endEarly) {Log.i(this, "Ending early -- isTheaterModeOn=%s, letDialerHandleRinging=%s, " +"isSelfManaged=%s, hasExternalRinger=%s, silentRingingRequested=%s, " +"isWorkProfileInQuietMode=%s",isTheaterModeOn, letDialerHandleRinging, isSelfManaged, hasExternalRinger,isSilentRingingRequested, isWorkProfileInQuietMode);}// Acquire audio focus under any of the following conditions:// 1. Should ring for contact and there's an HFP device attached// 2. Volume is over zero, we should ring for the contact, and there's a audible ringtone//    present. (This check is deferred until ringer knows the ringtone)// 3. The call is self-managed.boolean shouldAcquireAudioFocus = !isWorkProfileInQuietMode &&((isHfpDeviceAttached && shouldRingForContact) || isSelfManaged) ||(call.isCVRSCall() && !endEarly && shouldRingForContact); // UNISOC: add for CVRS(customized video ringing signal)// Set missed reason according to attributesif (!isVolumeOverZero) {call.setUserMissed(USER_MISSED_LOW_RING_VOLUME);}if (!shouldRingForContact) {call.setUserMissed(USER_MISSED_DND_MODE);}mAttributesLatch.countDown();return builder.setEndEarly(endEarly).setLetDialerHandleRinging(letDialerHandleRinging).setAcquireAudioFocus(shouldAcquireAudioFocus).setRingerAudible(isRingerAudible).setInaudibleReason(inaudibleReason).setShouldRingForContact(shouldRingForContact).setSilentRingingRequested(isSilentRingingRequested).setWorkProfileQuietMode(isWorkProfileInQuietMode).build();
}

三、解决方案

修改 Ringer 是核心，通过 统计来电次数来计算是否达到响铃的阈值，是否响铃通过 isRingerAudible 变量控制，通过修改 isRingerAudible 达到响铃的条件，为了不影响未打开 Settings 值的逻辑，使用逻辑与 的短路效应将开关条件前置

其中 shouldForceRingForRepeatCaller 方法本来是考虑使用电话数据库查询的方式来实现，但原逻辑中存在超时限制，数据库查询耗时会导致 TimeoutException 异常，并且在 getRingerAttributes 方法中不能添加列表的增减操作会导致 ExecutionException 异常。

RingerAttributes 新增变量 mForceRing 和方法 isForceRing() 来控制是否响铃
