Saya memiliki layanan penagihan dalam aplikasi yang menyiapkan dua barang habis pakai dan satu tidak habis pakai.
Untuk yang tidak habis pakai, saya memeriksa daftar pembelian dan jika barang tersebut sudah dimiliki, saya ingin pengguna menahan diri untuk tidak membeli lagi dan malah menyediakan manfaatnya. Saya memiliki dua kelas: Guess.java (file Peluncur) dan Pembelian.java (file pengaturan penagihan dalam aplikasi)
Di dalam Guess.java
Intent intent = new Intent(Guess.this,Purchase.class);
intent.putExtra("buy_2x", "buy_2x");
startActivity(intent);
Buy_2x adalah non-consumable (pilihan beli ada 2 pada kode di bawah ini sedangkan consumable disebut pilihan beli 0 dan 1) yang saya maksud. Di dalam Pembelian.java kodenya adalah sebagai berikut
public class Purchase extends Activity {
IInAppBillingService mService;
private Bundle extras;
private int add=0;//add coins to the kitty
private int buying_choice;
private String ITEM_SKU_SELECTION;
private static final String TAG = "com.apps.guess.inappbilling";
IabHelper mHelper;
private ServiceConnection mServiceConn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String base64EncodedPublicKey = "<64-char> long";
Intent intent = getIntent();
String buy2x_recd =intent.getExtras().getString("buy_2x");
//this is a class that contains static variables and I am using choices
//0,1,2...choice 2 is for the non-consumable buy_2x
if(UserData.getBuying_choice()!=2) ITEM_SKU_SELECTION = selectbuyingChoice(UserData.getBuying_choice());
//callService() method referred below
if(buy2x_recd.equalsIgnoreCase("buy_2x"))callService();
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new
IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result)
{
if (!result.isSuccess()) {
Toast.makeText(getApplicationContext(), "In-app Billing setup failed: = ", Toast.LENGTH_LONG).show();
Log.d(TAG, "In-app Billing setup failed: ");
} else {
Log.d(TAG, "In-app Billing is set up OK");
mHelper.launchPurchaseFlow(Purchase.this, ITEM_SKU_SELECTION, 10001,mPurchaseFinishedListener, "");
mHelper.enableDebugLogging(true, TAG);
}
}
});
}//onCreate() ends
public void callService(){
mServiceConn = new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName name,
IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
Log.d("TEST", "mService ready to go!");
checkownedItems();
}
@Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}
};
bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);
}
private void checkownedItems()
{
try {
Bundle ownedItems = mService.getPurchases(3, getPackageName(), "inapp", null);
int response = ownedItems.getInt("RESPONSE_CODE");
if (response == 0) {

for (int i = 0; i < purchaseDataList.size(); ++i) {
String purchaseData = purchaseDataList.get(i);
String signature = signatureList.get(i);
String sku = ownedSkus.get(i);
if(sku.equalsIgnoreCase("buy_2x"))
{

Saya mendapat peringatan berikut:
Implicit intents with startService are not safe: Intent { act=com.android.vending.billing.InAppBillingService.BIND } android.content.ContextWrapper.bindService:517 Purchase.callService:107 Purchase.onCreate:68
Kesalahannya adalah sebagai berikut:
IabHelper(25782): In-app billing error: Unable to buy item, Error response: 5:Developer Error
UserData.java menyimpan beberapa nilai dan menulis data dalam file teks. Mereka tidak punya masalah.
Masalah apa ini? Tolong bantu. Terima kasih
