android audio模块接口

回答: Android的audio模块提供了一系列接口，包括Mediaplayer，Audiotrack，AudioService，AudioManager，AudioRecord和MediaRecorder等。这些接口位于Android的audio framework层，用于向上层提供音频功能的支持。\[1\]如果要实现Android的硬件抽象层，需要实现AudioHardwareInterface、AudioStreamOut和AudioStreamIn三个类，并将代码编译成动态库libaudio.so。AudioFlinger会连接这个动态库，并调用其中的createAudioHardware()函数来获取接口。\[2\]在Android的Audio系统中，相关的类位于android.media包中，Java部分的代码路径为frameworks/base/media/java/android/media。\[3\]
