GPS 를 얻어주는 클래스에 생성자나 set 메소드로 caller Activity를 파라미터로 전달하심 될 것 같은데요.
그리고, getSystemService는 Activity가 아닌 Context에서 얻는건데요?? caller에서 보낼때 Context를 보내주는게 맞을 것 같습니다.

아마 위에서 나온 오류는 GPS 좌표를 얻어주는 클래스가 extends Activity를 안해서 생기는 문제로 보이는데, 굳이 extends Activity를 하지 않아도 되는 클래스니 앞에 설명드린대로 Context를 주입해서 하심 됩니다.

답변 갑사드립니다. 그런데 오류 메세지는

이런 오류입니다.
그리고 caller가 Activity가 아닙니다. JNI테스트 중인데요 C++에서 안드로이드 GPS정보를 사용하려는것인데...테스트 방법이 없어서
아래 소스 같이 구성해서 테스트하려합니다.
-----TestActivity.java -----
