我正试图让应用账单3工作，不知道我做错了什么。我正在关注一个教程而且我被困住了。如果有人能帮助我开展工作，我将非常感激。
我只是想让最简单的静态测试工作。我可以通过手机获取，我正确导入了android.vending.billing和inappbillingservice.aidl。
我在NullPointerException获得SkuDetails = mservice.getSkuDetails(3, getPackageName(), "inapp", querySkus)。
我可能还有其他错误，但就我现在所做的那样。
public class MainActivity extends ActionBarActivity {
IInAppBillingService mservice;
ServiceConnection connection;
String inappid= "android.test.purchased";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
System.out.println("oncreabte!!!!!!!!");
ServiceConnection connection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
// TODO Auto-generated method stub
mservice = IInAppBillingService.Stub.asInterface(service);
System.out.println("it conncekcted!!!!!!!!");
}
@Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
System.out.println("it disconncected!!!!!!!!!!");
}
};
bindService (new Intent(
"com.android.vending.billing.InAppBillService.BIND"),
connection, Context.BIND_AUTO_CREATE);
Button purchaseBtn = (Button)findViewById(R.id.purchase);
System.out.println("bind!!!!!!!!!!");
purchaseBtn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
System.out.println("onclccccick");
ArrayList skuList = new ArrayList();
skuList.add(inappid);
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST",skuList);
// Bundle SkuDetails;
System.out.println("right befor try!!!");
Bundle SkuDetails;
try{
System.out.println("right "+ skuList.get(0));
System.out.println( "mine! "+querySkus);
SkuDetails = mservice.getSkuDetails(3,
getPackageName(), "inapp", querySkus);
int responce = SkuDetails.getInt("RESPONCE_CODE");
System.out.println("Endddd!!!" + responce);
if(responce ==0){
System.out.println("Endddd!!!");
ArrayList<String> responceList = SkuDetails.getStringArrayList("DETAILS_LIST");
for (String thisResponse : responceList){
JSONObject object = new JSONObject(thisResponse);
String sku = object.getString("productId");
String price = object.getString("price");
if (sku.equals("inappid")){
System.out.println("price" + price);

我得到了它的工作，我知道这远远不是最好的例子，但对于这个问题，我找不到一个有效的例子，所以希望这会对某人有所帮助。我打算写一个关于源文件外观的图像，这让我有点困惑，但没有足够的代表来添加img。我的例子来自，https://www.youtube.com/watch?v=-h2ESH71hAI感谢他。
