Example : Find your view by id with view
EditText testttET = view.findViewById(R.id.testtt);
String text = testttET.getText().toString();
check if your text is not empty
if(!text.equals("")){
double value = Double.parseDouble(text);

The root cause of your crash is this bit:
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.Resources$Theme android.content.Context.getTheme()' on a null object reference
at android.app.AlertDialog.resolveDialogTheme(AlertDialog.java:224)
at android.app.AlertDialog$Builder.<init>(AlertDialog.java:454)
at com.example.vaidish.myapplication.Background.<init>(Background.java:25)
This says that you're passing null to the AlertDialog.Builder constructor. You could be doing that explicitly, like:
new AlertDialog.Builder(null)
or you could be doing it unintentionally, like:
new AlertDialog.Builder(mContext)
Check line 25 of your Background class, and make sure you're passing a non-null Context instance to the builder.

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.
