Android P版本添加雙卡鈴聲

1 添加ro.config.ringtone_sim2值作爲默認SIM2的鈴聲

方法一：
在 build/make/tools/buildinfo.sh中添加

 ro.config.ringtone_sim2=Cherry_ROCK.ogg

方法二：
在build/make/target/product/full_base.mk中添加

 # Additional settings used in all AOSP builds
 PRODUCT_PROPERTY_OVERRIDES := \
     ro.config.ringtone_sim2=Cherry_Tone_1.ogg \
     ro.config.ringtone=Cherry_Caribbean.ogg \
     ro.config.notification_sound=Cherry_Tone_1.ogg

這種添加需要額外加權限，否則在代碼中通過SystemProperties獲取不到值
在system/sepolicy/public/property_contexts中添加如下代碼

ro.config.ringtone u:object_r:exported2_config_prop:s0 exact string

2 在frameworks/base/media/java/android/media/MediaScanner.java中做如下修改

5 由於更新了Settings，需要更新frameworks/base/api/current.txt文件

public class RingtoneManager {
field public static final int TYPE_RINGTONE_SIM2 = 8; // 0x8  新增

此值可在編譯之後自行對比變動

6 framework中主要修改就是這些，再看下數據庫更新，主要涉及文件

SettingsProtoDumpUtil.java和SettingsProvider.java
SettingsProvider/src/com/android/providers/settings/SettingsProtoDumpUtil.java

private static void dumpProtoSystemSettingsLocked(

        dumpSetting(s, p,

        throw new FileNotFoundException("Direct file access no longer supported; "
                + "ringtone playback is available through android.media.Ringtone");
    }

    } else if (Settings.System.ALARM_ALERT.equals(name)) {
        cacheName = Settings.System.ALARM_ALERT_CACHE;
    }

7 在packages/services/Telecomm/src/com/android/server/telecom/RingtoneFactory.java文件中修改
