Android GO 版本锁屏声音无效问题

问题描述

Android go版本在设置中打开锁屏音开关，息屏灭屏还是无声音

排查

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\keyguard\KeyguardViewMediator.java

private void setupLocked() {...String soundPath = Settings.Global.getString(cr, Settings.Global.LOCK_SOUND);Log.d("TAG", "playSound soundPath = " + soundPath);if (soundPath != null) {mLockSoundId = mLockSounds.load(soundPath, 1);}if (soundPath == null || mLockSoundId == 0) {Log.w(TAG, "failed to load lock sound from " + soundPath);}soundPath = Settings.Global.getString(cr, Settings.Global.UNLOCK_SOUND);if (soundPath != null) {mUnlockSoundId = mLockSounds.load(soundPath, 1);}if (soundPath == null || mUnlockSoundId == 0) {Log.w(TAG, "failed to load unlock sound from " + soundPath);}soundPath = Settings.Global.getString(cr, Settings.Global.TRUSTED_SOUND);if (soundPath != null) {mTrustedSoundId = mLockSounds.load(soundPath, 1);}if (soundPath == null || mTrustedSoundId == 0) {Log.w(TAG, "failed to load trusted sound from " + soundPath);}...}

追踪到锁屏声音相关类，获取锁屏音资源路径处打log，发现soundPath 是空的，说明没有获取到锁屏音资源文件

相关系统音频资源通常会在编译时拷贝进product/media/audio/ui/ 目录
adb shell 进入 product/media/audio/ui/ 目录下，发现没有Lock.ogg文件，说明没有拷贝，mk文件没有执行拷贝动作

进入frameworks\base\data\sounds 路径下查看相关资源文件和mk文件
在这里插入图片描述
AudioPackageGo.mk文件是GO版本编译到的mk文件，进入查看

确实没有复制Lock.ogg 所以在这里加上

	$(LOCAL_PATH)/effects/Undock.ogg:$(TARGET_COPY_OUT_PRODUCT)/media/audio/ui/Undock.ogg \$(LOCAL_PATH)/effects/Lock.ogg:$(TARGET_COPY_OUT_PRODUCT)/media/audio/ui/Lock.ogg \
