我在Android方面不是很有经验，而且我已经接管了其他人的工作，并被要求在第3号帐单中实施。
我已经调试了代码，并在此处找到了问题
//IF THE BUTTON IS VISIBLE, AND CLICKED, PURCHASE CALCULATOR
public void unlockCalculators(View v) {
String payload = "";
mHelper.launchPurchaseFlow(this, SKU_riskCalc, RC_REQUEST,
mPurchaseFinishedListener, payload); <---- LINE 250
Log.d("BP_EXPERT", "PURCHASE RISK CALC");
}
这是定义mPurchasedListener的地方
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener()
{
@Override
public void onIabPurchaseFinished(IabResult result, Purchase purchase)
{
Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase);
if (result.isFailure()) {
complain("Error purchasing: " + result);
}
if (!verifyDeveloperPayload(purchase)) {
complain("Error purchasing. Authenticity verification failed.");
return;
}
else if (purchase.getSku().equals(SKU_riskCalc)){
//UPDATE SHARED PREFERENCES HERE...
SharedPreferences prefs = getSharedPreferences("BloodPressure",MODE_PRIVATE);
SharedPreferences.Editor edit = prefs.edit();
edit.putBoolean("purchased_calcs", true);
edit.commit();
Log.d("BP_EXPERT", "PURCHASING RISK CALC");
//SELECT CORRECT LAYOUT AFTER PURCHASE
createStuff();
}
else if (purchase.getSku().equals(SKU_all)){
//UPDATE SHARED PREFERENCES HERE...
SharedPreferences prefs = getSharedPreferences("BloodPressure",MODE_PRIVATE);
SharedPreferences.Editor edit = prefs.edit();
edit.putBoolean("purchased_all", true);
edit.commit();
Log.d("BP_EXPERT", "PURCHASING ALL CONTENT");
//SELECT CORRECT LAYOUT AFTER PURCHASE
createStuff();
}
Log.d(TAG, "Purchase successful.");
}
};
当应用程序进入启动购买流程时，它被强制关闭。如果有人对可能出现的问题有任何想法，我会非常感激。 我遇到过这个问题，我不太确定是什么导致它，当我点击按钮时我在logcat中得到以下内容

我确信下面的一行会尝试显示一个对话框
mHelper.launchPurchaseFlow(this, SKU_riskCalc, RC_REQUEST,
mPurchaseFinishedListener, payload);
但某个地方你的活动被破坏了，因此对话框无法显示，应用程序崩溃。
修改 在您的类中声明一个Activity
类型的变量private Activity mActivityContext = null;
初始化变量
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mActivityContext = this;
// Your Rest of the code
}
然后在调用launchPurchaseFlow时使用变量而不是“ this ”
mHelper.launchPurchaseFlow(mActivityContext, SKU_riskCalc, RC_REQUEST,
mPurchaseFinishedListener, payload);
