AudioRecord uninitialized Error
来源：互联网 发布：python中的iteritems 编辑：程序博客网 时间：2024/05/16 19:39
andorid 录音时发现了一个诡异的问题:
Error code -20 when initializing native AudioRecord object.
IllegalStateException:"startRecording() called on an uninitialized AudioRecord."
是AudioRecord JNI层抛上来的错误.在2.3.6的三星S5830上出现.
查遍网络得不到解决方案.最后在
http://stackoverflow.com/questions/4342482/cannot-access-audiorecorder 得到解决方案.
:重启你的手机!
原因是,可能之前某次录音过程中你的程序崩溃了,java层没来得及调用
recordInstance.release(); 释放JNI层的资源,导致下次初始化AudioRecord的时候失败.
无论你重新打开应用,或是卸载再安装你的应用都不好使,好使的办法:重启手机.
不知道安卓底层做了什么.... 高版本的安卓手机还没发现这个问题.
