我正在尝试在我的应用中实现应用内结算API，但是当我运行我的应用时，它会产生异常。这是我第一次使用应用内结算API。这是我得到的异常的日志：

最后，我得到了整个工作，并没有得到这个异常“IAB助手没有设置。无法执行操作：queryInventory”或我得到的另一个“无法启动异步操作（消耗）因为另一个异步操作（消耗）正在进行中。“
您要做的第一件事是在IabHelper.java类中添加2个方法：
public boolean isAsyncInProgress(){
return mAsyncInProgress;
}
public boolean isSetupDone (){
return mSetupDone;
}
而不是你的主要活动：
public class MainActivity extends AppCompatActivity {
private IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
@Override
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
if (result.isFailure()) {
// handle error here
Toast.makeText(MainActivity.this,"error",Toast.LENGTH_LONG).show();
}
else{
// does the user have the premium upgrade?
mIsRemoveAdds = inventory.hasPurchase(SKU_REMOVE_ADDS);
if(!mIsRemoveAdds) {
Toast.makeText(MainActivity.this,"no premium",Toast.LENGTH_LONG).show();
mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
}else{
mAdView.setVisibility(View.GONE);
Toast.makeText(MainActivity.this,"premium",Toast.LENGTH_LONG).show();
}
}
}
};
private IabHelper.OnIabPurchaseFinishedListener mPurchasedFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
@Override
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
if (result.isFailure()) {
Log.d(TAG, "Error purchasing: " + result);
return;
}
else if (purchase.getSku().equals(SKU_REMOVE_ADDS)) {
// consume the gas and update the UI
mIsRemoveAdds = true;
mAdView.setVisibility(View.GONE);
Toast.makeText(MainActivity.this,"Purchase successful",Toast.LENGTH_LONG).show();
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String publicKey = s1+s2+s3+s4+s5;
mHelper = new IabHelper(this,publicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
@Override
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
//error
Log.d(TAG, "Proglem setting up in-app Billing: " + result);
}
if (result.isSuccess()) {
//Horay, IAB is fully set up!
Log.d(TAG, "Horay, IAB is fully set up!");
//queryPurchasedItems;
mHelper.queryInventoryAsync(mGotInventoryListener);
}
}
});
现在，正如Google guide建议的那样，我们必须检查用户在开始或简历方法中购买了哪些商品。在这里，我们需要在IabHelper.java类中添加两种方法。
private void queryPurchasedItems() {
//check if user has bought "remove adds"
if(mHelper.isSetupDone() && !mHelper.isAsyncInProgress()) {
mHelper.queryInventoryAsync(mGotInventoryListener);
}
}
@Override
protected void onStart() {
super.onStart();
queryPurchasedItems();
}
@Override
protected void onResume() {
super.onResume();
queryPurchasedItems();
isListEmpty();
}

您的OnIabSetupFinishedListener会检查 （！result.isSuccess（））
但是如果结果不成功，你不会返回或中止。
我认为你的mHelper.startSetup失败了，你没有处理这个失败。
