jstring jni_wallet_testJNI(JNIEnv env, jobject thiz, jstring fromJavaString)
{
char *a = NULL;
jstringTostr(env, fromJavaString, &a);
LOGI("Line %d", LINE);
char b[] = "这里是C层，接收来自java的数据：";
LOGI("char b : %s Line %d", b,__LINE__);
// strcat(b,a);//加上这句就崩了
LOGI("char b : %s Line %d",b, LINE);
jstring jstr;
LOGI("Line %d", LINE);
strToJString(env, (const int8u) b, &jstr);
LOGI("Line %d", LINE);
return jstr;
}
jstringTostr(env, fromJavaString, &a);jstring转string的操作是不是有问题，为什么把指向指针a的地址传进去，函数形参是不是char* &类型的，是不是只传a进去就可以了，再后面打印下a试试
jni的函数名要按规则来。
