신호 11 (SIGSEGV), 안드로이드

Question

내가 안드로이드에서 실행하려고, 안드로이드를위한 C의 \의 C++ 네이티브 응용 프로그램을 구축하고있는 고장 요지의 deadbaad 얻기 그러나 나는 다음과 같은 오류 얻을 :

나는 노력을 1.6, 2.1, 2.2 안드로이드 : 나는 결과

/usr/local/google/home/digit/android/main/cupcake/android/bionic/libc/unistd/brk.c:45 

내가 모든 플랫폼이 무엇입니까 다음 있어보다 주소 0001072a와 arm-eabi-addr2line을 사용할 수 있습니다.

내 프로그램이 JNI 측에서 채워지는 버퍼에서 값을 검색하려고 할 때 충돌이 발생합니다.

다음은 JNI가 채워진 버퍼에서 값을 가져 오는 데 사용하는 코드입니다.

for(int j = 0; j < count; j++) 
{ 
    len = outBuf.getInt(); 
    CharBuffer cbuf = outBuf.asCharBuffer(); 
    CharSequence cS = cbuf.subSequence(0, len); 
    wordsPage[j] = cS.toString(); 
    outBuf.position(outBuf.position()+ (len*2)); 
} 

그리고 당신은 자바와 JNI 사이의 메모리를 공유하는 나에게 어떤 완전한 증거 메커니즘을 알려 주시기 바랍니다 수 있습니다.

Answer 1

크기는 wordsPage입니다. 범위 밖의 모든 색인에 문제가 있습니까? dalvik.vm.checkjni=true을 사용하도록 설정하고 더 많은 정보를 참조하십시오.
