我正在尝试使用NexGo SDK通过NexGo p200打印收据，但是当我运行应用程序时，我得到了下图所示的错误。
该守则是：
public void print() {
try {
deviceEngine =APIProxy.getDeviceEngine(MainActivity.this);
Log.e("device",deviceEngine.toString());
}catch (RuntimeException e){
e.printStackTrace();
}
printer = deviceEngine.getPrinter();
printer.setTypeface(Typeface.DEFAULT);
printer.initPrinter();
printer.setTypeface(Typeface.DEFAULT);
printer.setLetterSpacing(5);
printer.appendPrnStr(getString(R.string.print_merchantname), 24, AlignEnum.LEFT, false);
printer.appendPrnStr(getString(R.string.print_merchantno), 24, AlignEnum.LEFT, false);

printer.appendPrnStr("---------------------------", 24, AlignEnum.LEFT, false);
printer.appendPrnStr(getString(R.string.print_merchant_dan), 24, AlignEnum.RIGHT, false);
printer.startPrint(false, new OnPrintListener() {
@Override
public void onPrintResult(final int retCode) {
runOnUiThread(new Runnable() {
@Override

}
});
}

这可能与java.library.path系统属性不正确有关。您可以尝试通过传递-Djava.library.path=<your-directory-containing-the-so-file>参数来修复它。
