ndk 사용 중 에러. libserial_port.so has text relocations. This is wasting memory and prevents security hardening. Please fix.

Question

안녕하세요.

 

초보 안드로이드 개발자입니다.

 

안드로이드에서 ndk 사용 중 이슈가 발견되었습니다.

 

아래는 해당 소스입니다.

public NFCManager(){
      mResource = PollbookApplication.getInstance();
      mManager = (UsbManager) mResource.getSystemService(Context.USB_SERVICE);
      String dev = "/dev/ttyACM";
      for(int i=0; i<10; i++){
         File f = new File(dev+i);
         if(f.exists()){
            dev = f.getAbsolutePath();
            break;
         }
      }
//     setPermission2NFC(dev);
      mNfcHandler = new JRMHandler(new SerialPortConfig(dev, 115200, 0));
      mNfcHandler.setListener(new JRMParser(this));
//    mPermissionIntent = PendingIntent.getBroadcast(mResource, 0, new Intent(ACTION_USB_PERMISSION), 0);
//    IntentFilter filter = new IntentFilter();
//    filter.addAction(ACTION_USB_PERMISSION);
//    filter.addAction(UsbManager.ACTION_USB_DEVICE_DETACHED);
   }
