Question

我在市场上有一款应用低音增强效果的全球音频组合应用。不幸的是，自4.0.3以来，音频会话0的使用已被弃用，我无法找到解决方法。有没有办法扫描音频会话ID？这是我的logcat：

Answer 1

它可能已被弃用，但是对全局输出组合（会话0）应用效果应该仍然可以在ICS和JB中使用，只要您获得MODIFY_AUDIO_SETTINGS权限并且您没有＆＃39 ; t也对0以外的会话应用任何效果。

这可能会抓住一根稻草但看着你的堆栈跟踪，但我怀疑你试图应用的音频效果可能根本不受支持。

您可以尝试调用queryEffects()并遍历Descriptor个对象，检查您是否首先支持您尝试应用的音频效果类型
