我已经在我的应用程序中实现了应用程序购买，我使用了“TrivialDrive”示例作为应用程序内计费的第3版，我已经通过使用静态响应对应用程序进行了测试，所有工作均符合预期。
但是，当我从市场上下载应用程序时，成功购买后应用程序会崩溃，
我的代码已成功购买
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase);
if (result.isFailure()) {
complain("Error purchasing: " + result);
}
if (purchase != null) {
if (purchase.getSku().equals(Constants.IN_APP_PURCHASE_PRODUCT_ID)) {
// bought the premium upgrade!
String message = getResources().getString(R.string.app_purchase_successful_msg);
mIsPremium = true;
updateUi(mIsPremium);
successAlert(message);
}
}
}
};
我已经在成功购买时设置了消息，但是当我从中成功购买时，我看不到此消息(表示那些亚麻布未执行)，成功付款后应用程序崩溃了。
重新启动应用程序并尝试购买已购买的商品时。
我从开发人员控制台收到崩溃报告。

它在此行的onActivityResult()方法中引发的Null指针异常
if (!mHelper.handleActivityResult(requestCode, resultCode, data))
方法是这样的
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data);
// Pass on the activity result to the helper for handling
if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
// not handled, so handle it ourselves (here's where you'd
// perform any handling of activity results not related to in-app
// billing...
super.onActivityResult(requestCode, resultCode, data);
} else {
Log.d(TAG, "onActivityResult handled by IABUtil.");
}
}
它在静态响应上工作得很好，但是在我从市场上购买时会崩溃。
最佳答案
我通过简单地通过使我的IabHelper成员变量(mHelper)静态来解决了此问题
