Question

Android应用内结算购买活动正在崩溃该应用。

我有一个应用内结算活动，购买了1个月内删除广告的订阅。

但是当我点击调用结算活动的删除广告按钮时，应用程序正在崩溃。

这是我的logcat输出：

.content
{
  padding-top: 1em;
  padding-bottom: 1em;
  background-color: #fec321;
  text-align: center;
  overflow: hidden;
}

.content .photo
{
  position: relative;
  border: solid .75em #ffffff;
  -webkit-box-shadow: 2px 2px 2px 0px rgba(0,0,0,0.75);
  -moz-box-shadow: 2px 2px 2px 0px rgba(0,0,0,0.75);
  box-shadow: 2px 2px 2px 0px rgba(0,0,0,0.75);
  display: inline-block;
}

.content picture, .content img, .content .description span
{
  position: relative;
  width: 14em;
  height: 14em;
  display: block;
}

.content .description
{
  position: relative;
  border: solid .75em #ffffff;
  -webkit-box-shadow: 2px 2px 2px 0px rgba(0,0,0,0.75);
  -moz-box-shadow: 2px 2px 2px 0px rgba(0,0,0,0.75);
  box-shadow: 2px 2px 2px 0px rgba(0,0,0,0.75);
  display: inline-block;
}

这是我的订阅按钮活动：

这是setbilling函数：

    bsubscribe.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        if (billing_error == "") {
            if (!isSubscribed)
                mHelper.launchPurchaseFlow(getParent(), SKU_SUBSCRIPTION, 9999, mPurchaseFinishedListener,"");
            else
                Toast.makeText(mContext, getResources().getString(R.string.already_subs), Toast.LENGTH_SHORT).show();
        } else
            Toast.makeText(mContext, "There's some error in billing : " + billing_error, Toast.LENGTH_LONG).show();
    }
});

}

从活动的OnCreate调用设置结算。

当我点击删除广告按钮（bsubscribe）

时，应用程序崩溃了

Answer 1

很难准确地说明所提供的代码，但看起来getParent()的调用在onClick方法中返回null。然后在IabHelper.java的第431行，您在空对象上调用startIntentSenderForResult。
