Android应用内结算购买活动正在崩溃应用。
我有一个应用内结算活动，购买订阅以删除广告1个月。
但是当我点击调用结算活动的删除广告按钮时，该应用程序正在崩溃。
这是我的logcat输出：

这是我的订阅按钮活动：
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();
}
});
}
这是setbilling函数：
private void setInAppBilling() {
mHelper = new IabHelper(mContext, bill_key);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (mHelper == null)
return;
if (!result.isSuccess()) {
Log.d("billing", "probelem in setting billing" + result);
billing_error = "" + result;
}
if (result.isSuccess()) {
Log.d("billing", "In app billing is set up");
mHelper.queryInventoryAsync(new IabHelper.QueryInventoryFinishedListener() {
@Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
if (inv.getPurchase(SKU_SUBSCRIPTION) == null) {
edit.putBoolean("subscription", false);
edit.commit();
} else {
edit.putBoolean("subscription", true);
edit.commit();
bsubscribe.setVisibility(View.GONE);
}
}
});
}
}
});
}
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase info) {
if (result.isFailure()) {
Toast.makeText(mContext, getResources().getString(R.string.error_subs), Toast.LENGTH_SHORT).show();
return;
}
if (info.getSku().equals(SKU_SUBSCRIPTION)) {
Toast.makeText(mContext, getResources().getString(R.string.success_subs), Toast.LENGTH_SHORT).show();
edit.putBoolean("subscription", true);
edit.commit();
}
}
};
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
很难准确地说明所提供的代码但是看起来getParent()的调用在你的onClick方法中返回null。然后在IabHelper.java的第431行，你在一个空对象上调用startIntentSenderForResult。
