Question

我在264和163两个文件中有错误，但在编辑器中看起来很好

第264行：

if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {

第163行：

mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {

我无法找到为什么我的活动无法启动 logcat的：

似乎是IabHelper的一个问题。方法queryIntentServices返回null，而不是空列表。

尝试更新此代码：

Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {
    // service available to handle that Intent
    mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
}
else {
    // no service available to handle that Intent
    if (listener != null) {
        listener.onIabSetupFinished(
                new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,
                "Billing service unavailable on device.")); 
    }
}

到此：

Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
List<ResolveInfo> intentServices = mContext.getPackageManager().queryIntentServices(serviceIntent, 0);

if (intentServices != null && intentServices.isEmpty() == false) {
    // service available to handle that Intent
    mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
}
else {
    // no service available to handle that Intent
    if (listener != null) {
        listener.onIabSetupFinished(
                new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,
                "Billing service unavailable on device.")); 
    }
}
