Re: ERROR:org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException...
Below is the full stack trace.
Could it possibly be because of empty columns/rows?

Unable to start activity ComponentInfo{com.viralandroid.test/com.paypal.android.sdk.payments.PaymentActivity}:

How could I solve the problem below? I searched a lot but I didn't figure out.
I am using a fragment instead of an activity to call PaymentActivity.
Thanks in advance.
There is a piece of code below.
public void executarPagtoPayPal()
{
SearchResultsAdapter searchResultsAdapter = new SearchResultsAdapter(getActivity(), new ArrayList<Produto>());
PayPalPayment coisasAComprar = searchResultsAdapter.prepararCarrinhoFinal();
Intent i = new Intent(getActivity(), PaymentActivity.class);
i.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, payPalConfiguration);
i.putExtra(PaymentActivity.EXTRA_PAYMENT, coisasAComprar);
startActivityForResult(i,CODIGO_PAGTO);
}

It looks like the contents of the PayPalPayment that you are putting in the Intent are not correct. Please validate that this object has all the correct data.
