정말 자괴감에 빠집니다… 으으으으………….
JNI라는 걸 좀 해보려고 javah 라는 header 파일 생성기를 좀 써보려고 노력중이었습니다.
근데 아무리 쓰여진데로
javah -classpath ../../android.jar;../bin/classes; org.apache.NativeAdd
를 쳐도 안되는 겁니다.
1. 경로명이 잘못됐나?
2. 경로명을 따옴표로 묶어주어야 하나?
2. 클래스 파일을 잘못 만들었나?
3. android.jar하고 뭔가 관련이 있나?
4. access 할 수 없다니.. 권한 문제인가..
5. 파일을 왜 못찾는다지?
……
결국 원인은 무엇인고 하니..
javah의 -verbose 옵션을 켰더니 다음과 같이 나오는군요.
dasomoli@dasomoli-ubuntu804:~/CallNative/src$ javah -classpath “../../android.jar;../bin/classes;” -verbose org.apache.NativeAdd
error: cannot access org.apache.NativeAdd

Error: No classes were specified on the command line. Try -help.
아시겠습니까?
네.. 그렇습니다. ‘;’ 대신 ‘:’를 써주어야 하는 겁니다.
이렇게 해주어야 되는 것이었습니다.
javah -classpath ../../android.jar:../bin/classes: org.apache.NativeAdd
그래서 결과는 다음과 같이 나옵니다.
dasomoli@dasomoli-ubuntu804:~/CallNative/src$ javah -classpath “../../android.jar:../bin/classes:” -verbose org.apache.NativeAdd
