在我正在Android（4.2.2）上开发的应用程序中，我一直收到致命信号11错误。我不知道为什么，它只是从NDK调用的简单方法。我是新来的，所以如果你看到我不能做的事情，请感激不尽。
背后的故事：我需要实施NDK AES（例如：http://en.wikipedia.org/wiki/AES_implementations），因为在Android中这很慢。
由于
这是我的java代码：
package sk.anext.ecukrovka.ws;
public class AESCrypt {
private static final String TAG = "AESCrypt";
static {
System.loadLibrary("aes256");
}
public class aes256_context {
public byte[] key = new byte[32];
public byte[] enckey = new byte[32];
public byte[] deckey = new byte[32];
}
public native void aes256test(aes256_context ctx);
public AESCrypt(AESKey key) throws GeneralSecurityException {
Log.d(TAG, "This is just simple test of NDK");
aes256_context ctx = new aes256_context();
aes256test(ctx); //Fatal signal 11 (SIGSEGV)
Log.d(TAG, "Never reached code..");
}
}
这是C代码..
