Android в -исключение для выставления счетов за приложение -при нажатии кнопки «Купить» и последующем нажатии «Назад» с экрана покупки
Когда пользователь нажимает кнопку покупки, он попадает на экран воспроизведения Android, чтобы купить элемент приложения -. Но когда они нажимают назад, они получают это исключение о том, что не могут запустить службу выставления счетов :

at com.problemio.ExtraHelpActivity.access$4(ExtraHelpActivity.java:565)

в строке 561 у меня есть этот код:
private void prependLogEntry(CharSequence cs) {
SpannableStringBuilder contents = new SpannableStringBuilder(cs);
contents.append('\n');
contents.append(mLogTextView.getText()); // Line 561
mLogTextView.setText(contents);
}
в строке 569 у меня есть этот код:
private void logProductActivity(String product, String activity) {
SpannableStringBuilder contents = new SpannableStringBuilder();
contents.append(Html.fromHtml("<b>" + product + "</b>: "));
contents.append(activity);
prependLogEntry(contents); // Line 569
}
Кстати, что это за журнал? Это действительно необходимо? Может стоит закомментировать эти методы?
В любом слючае,другая строка, на которую указывает ошибка, - 187, и вот код для этого:
@Override
public void onRequestPurchaseResponse(RequestPurchase request,
ResponseCode responseCode) {
if (Consts.DEBUG) {
Log.d(TAG, request.mProductId + ": " + responseCode);
}
if (responseCode == ResponseCode.RESULT_OK) {
if (Consts.DEBUG) {
Log.i(TAG, "purchase was successfully sent to server");
}
logProductActivity(request.mProductId, "sending purchase request");
} else if (responseCode == ResponseCode.RESULT_USER_CANCELED) {
if (Consts.DEBUG) {
Log.i(TAG, "user canceled purchase");
}
logProductActivity(request.mProductId, "dismissed purchase dialog");
// This is line 187 right above this comment.
} else {
if (Consts.DEBUG) {
Log.i(TAG, "purchase failed");
}
logProductActivity(request.mProductId, "request purchase returned " + responseCode);
}
}
Итак, вы видите, у него продолжают возникать проблемы с регистрацией. Что это за журнал? Где я могу это увидеть? Как исправить, чтобы ошибок не было?
Я не уверен, но, возможно, большая проблема в том, что запрос недействителен. Почему запрос может быть нулевым здесь?
