我认为标题是不言自明的...... 这是在java中调用函数
...
char[] path = stringPath.toCharArray();
char[] result = new char[256];
Log.e("ndk", "starting native method");
pcmEncoder.encodePCM(path, result);
...
这是我认为可能错误的C代码：
JNIEXPORT jint JNICALL Java_cz_hundredspires_que_SignalProcessor_encodePCM (JNIEnv *env, jobject obj, jcharArray jcha1, jcharArray jcha2)
{
char *FileName = (*env)->GetCharArrayElements(env, jcha1, NULL);
char *BestOutput = (*env)->GetCharArrayElements(env, jcha2, NULL);
...
(*env)->ReleaseCharArrayElements(env, FileName, jcha1, 0);
(*env)->ReleaseCharArrayElements(env, BestOutput, jcha2, 0);
return 1;
}
jcha1是文件路径，jcha2是用于写入孔函数结果的数组，我以后应该可以在java代码中读取它。
我无法解决它。有人可以帮我吗？ 感谢
