Android系统双卡铃声实现

根据我们之前的流程梳理，我们了解了铃声的播放，铃声的设置。今天我们就来详细讲解双卡铃声的实现。

一、配置双卡铃声

我们首先需要在配置文件中添加SIM卡二的配置

路径：platform/build/target/product/full_base.mk

# Additional settings used in all AOSP builds
PRODUCT_PROPERTY_OVERRIDES := \ro.config.ringtone=Ring_Synth_04.ogg \ro.config.ringtone_2=Ring_Synth_04.ogg \ro.config.notification_sound=pixiedust.ogg

二、FrameWork配置

我们需要添加一些标志位和路径信息

路径：/frameworks/base/core/java/android/provider/Settings.java

三、来电监听

这一步做的主要是区分那个SIM卡来电，并播放相应铃声

路径：/vendor/mediatek/proprietary/packages/services/Telecomm/src/com/android/server/telecom/RingtoneFactory.java

import android.telecom.PhoneAccountHandle;
import android.telephony.SubscriptionInfo;
import android.telephony.SubscriptionManager;
import com.android.internal.telephony.PhoneConstants;public Ringtone getRingtone(Call incomingCall) {...........if(ringtoneUri != null && userContext != null) {// Ringtone URI is explicitly specified. First, try to create a Ringtone with that.ringtone = RingtoneManager.getRingtone(userContext, ringtoneUri);}if(ringtone == null) {// Contact didn't specify ringtone or custom Ringtone creation failed. Get default// ringtone for user or profile.Context contextToUse = hasDefaultRingtoneForUser(userContext) ? userContext : mContext;Uri defaultRingtoneUri;if (UserManager.get(contextToUse).isUserUnlocked(contextToUse.getUserId())) {defaultRingtoneUri = RingtoneManager.getActualDefaultRingtoneUri(contextToUse,RingtoneManager.TYPE_RINGTONE);//add by xiangzaixiansheng for support dual sim card ringtones  @{int slotId = getSlotId(mContext,incomingCall.getTargetPhoneAccount());if (slotId == PhoneConstants.SUB2) {defaultRingtoneUri = RingtoneManager.getActualDefaultRingtoneUri(contextToUse,RingtoneManager.TYPE_RINGTONE_2);}//add by xiangzaixiansheng for support dual sim card ringtones @}} else {defaultRingtoneUri = Settings.System.DEFAULT_RINGTONE_URI;}
.........
}private int getSlotId(Context context, PhoneAccountHandle phoneAccountHandle) {int slotIndex = SubscriptionManager.INVALID_SIM_SLOT_INDEX;SubscriptionManager sm = SubscriptionManager.from(mContext);List<SubscriptionInfo> subInfoList = sm.getActiveSubscriptionInfoList();if (phoneAccountHandle != null && !TextUtils.isEmpty(phoneAccountHandle.getId())&& subInfoList != null) {for (SubscriptionInfo subInfo : subInfoList) {if (phoneAccountHandle.getId().startsWith(subInfo.getIccId())) {slotIndex = subInfo.getSimSlotIndex();}}}return slotIndex;}

四、Setting中的设置

这里面其实比较简单，只要模仿SIM卡1来添加就可以了

路径：/packages/apps/Settings/res/xml/sound_settings.xml

<com.android.settings.DefaultRingtonePreferenceandroid:key="ringtone2"android:title="@string/ringtone_title"android:dialogTitle="@string/ringtone_title"android:summary="@string/summary_placeholder"android:ringtoneType="ringtone_2" />

路径：/packages/apps/Settings/src/com/android/settings/notification/SoundSettings.java

 private static List<AbstractPreferenceController> buildPreferenceControllers(Context context,SoundSettings fragment, VolumeSeekBarPreference.Callback callback,Lifecycle lifecycle) {final List<AbstractPreferenceController> controllers = new ArrayList<>();controllers.add(new ZenModePreferenceController(context));controllers.add(new EmergencyBroadcastPreferenceController(context, KEY_CELL_BROADCAST_SETTINGS));controllers.add(new VibrateWhenRingPreferenceController(context));// === Volumes ===controllers.add(new AlarmVolumePreferenceController(context, callback, lifecycle));controllers.add(new MediaVolumePreferenceController(context, callback, lifecycle));controllers.add(new NotificationVolumePreferenceController(context, callback, lifecycle));controllers.add(new RingVolumePreferenceController(context, callback, lifecycle));// === Phone & notification ringtone ===controllers.add(new PhoneRingtonePreferenceController(context));//add by xiangzaixiansheng for support dual sim card ringtones  @{controllers.add(new PhoneRingtone2PreferenceController(context));//add by xiangzaixiansheng for support dual sim card ringtones  @}controllers.add(new AlarmRingtonePreferenceController(context));controllers.add(new NotificationRingtonePreferenceController(context));
......
}

路径：/packages/apps/Settings/src/com/android/settings/notification/PhoneRingtone2PreferenceController.java

package com.android.settings.notification;import android.content.Context;
import android.media.RingtoneManager;import com.android.settings.Utils;public class PhoneRingtone2PreferenceController extends RingtonePreferenceControllerBase {private static final String KEY_PHONE_RINGTONE_2 = "ringtone2";String sim2 = "";public PhoneRingtone2PreferenceController(Context context) {super(context);}@Overridepublic String getPreferenceKey() {return KEY_PHONE_RINGTONE_2;}@Overridepublic boolean isAvailable() {if(simNumberCard == 0) {return false;} else if (simNumberCard ==1 ) {return isShowSim();} else if (simNumberCard == 2) {return Utils.isVoiceCapable(mContext);}       return Utils.isVoiceCapable(mContext);}public boolean isShowSim(){sim2=getSimName(1);if(sim2 !=  null && sim2 !="" && !sim2.equals("")) {return Utils.isVoiceCapable(mContext);} else {return false;}}@Overridepublic int getRingtoneType() {return RingtoneManager.TYPE_RINGTONE_2;}
}

路径：/packages/apps/Settings/src/com/android/settings/notification/RingtonePreferenceControllerBase.java

这个里面需要配置的一些何时会显示SIM卡铃声选项显示的时机。例如我们的需求就是如果没有SIM卡2就不显示SIM卡2的铃声设置选项。这里面我们就忽略这些操作了。这里面就给出一个方法，如果获得当前卡槽的SIM卡信息。

   public  String getSimName(int phoneId) {mSubInfoList = mSubscriptionManager.getActiveSubscriptionInfoList();for (SubscriptionInfo info : mSubInfoList) {if (null != info && phoneId == info.getSimSlotIndex() &&null != info.getDisplayName() && !"".equals(info.getDisplayName())) {return info.getDisplayName().toString();}}return "";}
