我試圖讓應用程序結算3工作，不知道我做錯了什麼。我正在跟着一個教程，我被卡住了。如果有人能夠幫助我實現這個目標，我會非常感激。在應用程序結算中，getskudetails零點異常？
我只是想獲得最簡單的靜態測試工作。我可以在手機上獲得，我正確導入了android.vending.billing和inappbillingservice.aidl。
我收到NullPointerException在SkuDetails = mservice.getSkuDetails(3, getPackageName(), "inapp", querySkus)。
我可能還有其他錯誤，但這就像我現在做的那樣。
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);
Bundle buyIntentBundle = mservice.getBuyIntent(3, getPackageName(),
sku, "inapp", "bGoa+V7g/yqDXvKRqq+JTFn4uQZbPiQJo4pf9RzJ");
PendingIntent pendingIntent = buyIntentBundle.getParcelable("BUY_INTENT");
startIntentSenderForResult(pendingIntent.getIntentSender(),
1001, new Intent(), Integer.valueOf(0), Integer.valueOf(0),
Integer.valueOf(0));
}
}
}
}
catch (RemoteException e) {
System.out.println("RemoteE");
e.printStackTrace();
}
catch (JSONException e) {
System.out.println("Remotejso");
e.printStackTrace();
}
catch (SendIntentException e) {
System.out.println("Remotein");
e.printStackTrace();
}
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == 1001) {
String purchaseData = data.getStringExtra("INAPP_PURCHASE_DATA");
if (resultCode == RESULT_OK) {
System.out.println("resuuut goood");
try{
JSONObject jo = new JSONObject(purchaseData);
String sku = jo.getString(inappid);
Toast.makeText(MainActivity.this,
"u have bought"+ sku,
Toast.LENGTH_LONG).show();
}
catch(JSONException e){
System.out.println("didnt work");
e.printStackTrace();
}
}
}
}
//end
public void onDestroy(){
super.onDestroy();
if(connection != null){
unbindService(connection);
}
}
}

此代碼是不是真的正確，它會工作，然後我得到「RESPONSE_CODE」 == 7這是BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNED我想FIGUR如何使用它，好像我在startIntentSenderForResult遇到了問題，並且當它工作時，不要認爲它是在onActivityResult上做的，不要回想起敬酒。當然別人可以更好地回答這個問題，我會很樂意回答這個問題，因爲我認爲它有效，可以幫助某人。 – user3705179 2014-10-12 19:59:50
