是不是你的什么控件没有初始化啊
04-13 23:39:21.113: W/System(18150): ClassLoader referenced unknown path: /data/app/com.example.newrecorder-1/lib/arm64
感觉这句话比较关键，你可以看一下提到的那个路径，是不是什么jar包没有add to path之类的
第一句（04-13 23:39:21.103）就说明你取到了 Null 值，没有考虑过对 Null 的处理吧，导致一路错下去最后闪退了。

setAudioSource failed
网上看到说是权限的问题，你可以参考试试

ClassLoader referenced unknown path: /data/app/com.example.newrecorder-1/lib/arm64 是不是用了SO包 然后没有导入对应arm64平台的
你的问题是setAudioSource failed.应该是有些控件没有被初始化
你确定输入的地址是正确或者是可用的嘛？
