cpp jni报错 -fpermissive

unsigned char *buf = jenv-> GetPrimitiveArrayCritical(outbuf,JNI_FALSE);这句话报错

错误： error: invalid conversion from 'void*' to 'unsigned char*' [-fpermissive]

解决办法：在.mk文件中加上LOCAL_CPPFLAGS := -fpermissive

编译时就不会报错了，但是会报warning: invalid conversion from 'void*' to 'unsigned char*' [-fpermissive]

这样我就满足了，毕竟可以编译成功。
