I've wrote an in app purchase test app to learn how to implement it in an application i've made.
I adapted the code from the TrivialDrive sample provided by google.
But it doesn't work, after my friend makes the payment the app crashes.
The code looks like this
public class MainActivity extends Activity {
String TAG = "AppPurchaseTest";
IabHelper mHelper;
boolean mIsPremium = false;
static final String SKU_PREMIUM = "premium";
static final int RC_REQUEST = 10001;
// User clicked the "Upgrade to Premium" button.
public void onUpgradeAppButtonClicked(View arg0) {
Log.d(TAG, "Upgrade button clicked; launching purchase flow for upgrade.");
// setWaitScreen(true);
mHelper.launchPurchaseFlow(this, SKU_PREMIUM, RC_REQUEST, mPurchaseFinishedListener);
}
//this is not working
// Callback for when a purchase is finished
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase);
int duration = Toast.LENGTH_SHORT;
if (result.isFailure()) {
// Oh noes!
// complain("Error purchasing: " + result);
// setWaitScreen(false);
Toast.makeText(getBaseContext(), "Fail :(", duration).show();
return;
}
Log.d(TAG, "Purchase successful.");
if (purchase.getSku().equals(SKU_PREMIUM)) {
// bought the premium upgrade!
Log.d(TAG, "Purchase is premium upgrade. Congratulating user.");
// alert("Thank you for upgrading to premium!");
mIsPremium = true;
Toast.makeText(getBaseContext(), "Successo: adesso sei premium", duration).show();
Button test = (Button) findViewById(R.id.test);
test.setVisibility(View.INVISIBLE);
// updateUi();
// setWaitScreen(false);
}
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String base64EncodedPublicKey = null;
// compute your public key and store it in base64EncodedPublicKey
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh noes, there was a problem.
Log.d(TAG, "Problem setting up In-app Billing: " + result);
}
// Hooray, IAB is fully set up!
}
});
}
#Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
if (mHelper != null) {
Log.d(TAG, "mHelper doesn't = null ");
mHelper.dispose();
mHelper = null;
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data);
// Pass on the activity result to the helper for handling
if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
// not handled, so handle it ourselves (here's where you'd
// perform any handling of activity results not related to in-app
// billing...
super.onActivityResult(requestCode, resultCode, data);
}
else {
Log.d(TAG, "onActivityResult handled by IABUtil.");
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
Can you spot something wrong? Something i forgot?
Also this tutorial https://developer.android.com/google/play/billing/billing_integrate.html
looks much simpler, but i don't understand how to implement it, is there a sample or something from which i can see how it's implemented? I just need a simple upgrade to premium purchase
It's very hard to make it work since i can't test it personally and everytime i test it i lose money :(
Took a long time to figure out on my project but you have to understand that your mPurchaseFinishedListener is called on a non rendering thread and before your application onResume() is called (just check the IabHelper code.
So if you try to do any rendering there it CAN crash because the rendering context is not restored yet.
In your case it is likely that:
Toast.makeText(getBaseContext(), "Successo: adesso sei premium", duration).show();
will crash, the same goes for
Button test = (Button) findViewById(R.id.test);
if you check the trivia example the textButton visibility is set to true, but the button itself is a class property that is assigned in the onCreate() method.
Let me know if this helps..
Per TrivialDrive You also need (this will fix it):
// We're being destroyed. It's important to dispose of the helper here!
#Override
public void onDestroy() {
super.onDestroy();
// very important:
if (mBroadcastReceiver != null) {
unregisterReceiver(mBroadcastReceiver);
}
// very important:
Log.d(TAG, "Destroying helper.");
if (mHelper != null) {
mHelper.disposeWhenFinished();
mHelper = null;
}
}

First time implementing in-app billing. i was able to complete first transaction, but second time while purchasing same item i am getting "Error response: 7:Item Already Owned" on onIabPurchaseFinished Method, how to make it re-purchase-able? any help would be appreciated.
screenshot of code structure is also attached.
Onclick purchase i am calling following method:
initilizeInAppPurchasePakages();
public void initilizeInAppPurchasePakages()
{
String base64EncodedPublicKey=getString(R.string.inAppBillingKey);
mHelper = new IabHelper(getActivity(), base64EncodedPublicKey);
mPurchaseFinishedListener
= new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase)
{
if (result.isFailure()) {
Log.d(TAG, "Error purchasing: " + result);
// Toast.makeText(getActivity(),"fail to purchase"+result, Toast.LENGTH_SHORT).show();
return;
}
else if (purchase.getSku().equals(purchaseItemId)) {
transactionId=purchase.getOrderId();
PackageFragment.isNeedToUpdate = true;
// consume the gas and update the UI
// Toast.makeText(getActivity(), "purchase successfully", Toast.LENGTH_SHORT).show();
mHelper.consumeAsync(purchase,
mConsumeFinishedListener);
}
else if (purchase.getSku().equals(purchaseItemId)) {
// give user access to premium content and update the UI
// Toast.makeText(getActivity(), "purchase successfully", Toast.LENGTH_SHORT).show();
}
}
};
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh no, there was a problem.
// Toast.makeText(getActivity(), "connection Error", Toast.LENGTH_SHORT).show();
}
else
{
// Toast.makeText(getActivity(), "connected successfully", Toast.LENGTH_SHORT).show();
Log.d(TAG, "Problem setting up In-app Billing: " + result);
mHelper.launchPurchaseFlow(getActivity(), purchaseItemId, 10001,
mPurchaseFinishedListener, "testing");
}
// Hooray, IAB is fully set up!
}
});
mConsumeFinishedListener =
new IabHelper.OnConsumeFinishedListener() {
public void onConsumeFinished(Purchase purchase, IabResult result) {
if (result.isSuccess()) {
serverUtilities.savePayment(pakageId,pakagePrice,transactionId);
// Toast.makeText(getActivity(), "consumed", Toast.LENGTH_SHORT).show();
// provision the in-app purchase to the user
// (for example, credit 50 gold coins to player's character)
}
else {
// handle error
}
}
};
}
Alright,
After spending time on reading documentation of google in app billing i found that i need to test in app billing through testing so what i did
test billing:
mHelper.launchPurchaseFlow(getActivity(), purchaseItemIdSKU, 10001,
mPurchaseFinishedListener, "testing");
Calling only first time to remove that already purchased entry record above the test billing line that i used above:
ArrayList skusToBeListed = null;
skusToBeListed = new ArrayList<String> ();
skusToBeListed.add (SKU_PREMIUM);
skusToBeListed.add (SKU_PREMIUM_ELITE);
skusToBeListed.add (SKU_PREMIUM_PLUS);
mHelper.queryInventoryAsync(true, skusToBeListed, mGotInventoryListener);
and once its done you can do many test bookings without any headache.
mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
#Override
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
if (result.isFailure()) {
//complain("Failed to query inventory: " + result);
return;
}
Purchase currentPurchase = inventory.getPurchase(purchaseItemIdSKU);
if(currentPurchase != null)
{
//Boolean mIsPremium = (currentPurchase != null && verifyDeveloperPayload(currentPurchase));
mHelper.consumeAsync(currentPurchase,mConsumeFinishedListener);
}
}
} ;
Note:
In case of test billing transaction id will not be returned so make sure how to handle that, i did tested my in app billing by hard coding it to following format: "GPA.1234-5678-9012-34567"
In short above code of mine was fine if i would i have used it on production mode, but in case of testing mode it was giving me errors that i explained and given solution how i solved it.
I have just implemented the in app billing functionality in my app.
I only have one product to unlock all premium features.
The purchase itself works, but after the purchase flow, my code obviously isn't able to recognise the success of the purchase, because there appears a complain window right after purchase saying "Articel already owned". So somehow the purchase flow is not recogniced to be successful. After i restart the app, the pro features are unlocked, because the querying of the inventory says, the pro features have been bought.
I am out of ideas, so here is my code:
// SKUs for our products: the premium upgrade (non-consumable)
String SKU_PREMIUM;
// (arbitrary) request code for the purchase flow
final int RC_REQUEST = 10001;
// The helper object
IabHelper mHelper;
// Provides purchase notification while this app is running
public IabBroadcastReceiver mBroadcastReceiver;
IabHelper.QueryInventoryFinishedListener mGotInventoryListener;

this.activity = context;
SKU_PREMIUM = skuPremium;
// Create the helper, passing it our context and the public key to verify signatures with

Btw: The code is a modified version of the **trivial drive* example.
Thanks in advance!
Although it's not the cleanest solution, just query the inventory again if you have a "already owned error". Then update the UI only according to the inventory query result
Thanks #DerAdler . I implemented it just the way you said and it worked.
I´m implementing In app Billing on my app, which let the user go to a "premium version of the app". In the premium version of the app the user will be able to click 3 buttons and use their functions. But that is not the problem.
The problem is how to check if the user has purchased the "premium version" yet and use all the app functions?
This is my code:
private void promptForUpgrade() {
AlertDialog.Builder upgradeAlert = new AlertDialog.Builder(this);
upgradeAlert.setTitle("Upgrade?");
upgradeAlert.setMessage("Do you want to upgrade to unlimited version?");
upgradeAlert.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//set progress dialog and start the in app purchase process
upgradeDialog = ProgressDialog.show(selector.this, "Please wait", "Upgrade transaction in process", true);
/* TODO: for security, generate your payload here for verification. See the comments on
* verifyDeveloperPayload() for more info. Since this is a SAMPLE, we just use
* an empty string, but on a production app you should carefully generate this. */
String payload = "developerinnovaciones#gmail.com";
try {
mHelper.launchPurchaseFlow(selector.this, SKU_PREMIUM, RC_REQUEST,
mPurchaseFinishedListener, payload);
} catch (IabHelper.IabAsyncInProgressException e) {
e.printStackTrace();
}
}
}).setNegativeButton("Nop", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
upgradeAlert.show();
}
and this is the OnIabPurchaseFinishedListener
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
= new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase)
{
// if we were disposed of in the meantime, quit.
if (mHelper == null) return;
if (result.isFailure()) {
alert("Error purchasing: " + result);
upgradeDialog.dismiss();
}
else if (purchase.getSku().equals(SKU_PREMIUM)) {
alert("Thank you for upgrade");
mIsPremium = true;
setUserStatus(true);
upgradeDialog.dismiss();
}
}
};
So basically I want to create a method which verify if the user is premium or not.
Hope you can help me :D
Within your onCreate method you should check the purchase status in your mHelper setup with an mHelper.queryInventoryAsync call.
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
Log.d(TAG, "Setup finished.");
if (!result.isSuccess()) {
// Oh noes, there was a problem.
complain("Problem setting up in-app billing: " + result);
isBillingSupported = false;
return;
}
// Hooray, IAB is fully set up. Now, let's get an inventory of stuff we own.
Log.d(TAG, "Setup successful. Querying inventory.");
mHelper.queryInventoryAsync(false, mGotInventoryListener);
isBillingSupported = true;
}
});
mGotInventory I defined like this
// Listener that's called when we finish querying the items we own
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result,
Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
if (result.isFailure()) {
complain("Failed to query inventory: " + result);
return;
}
Log.d(TAG, "Query inventory was successful.");
// Do we have the premium upgrade?
isPremium = inventory.hasPurchase(SKU_PREMIUM);
Log.d(TAG, "User is " + (isPremium ? "PREMIUM" : "NOT PREMIUM"));
updateUi();
Log.d(TAG, "Initial inventory query finished; enabling main UI.");
}
};
isPremium is a boolean flag defaulting to false.
The updateUi method enables/disables buttons depending on the isPremium state.
You will probably want to set isPremium and call updateUi on purchase completion as well to ensure the premium features are enabled immediately.
i am developing a app in android using in app subscription. i am trying to query my purchase items using IabHelper.QueryInventoryFinishedListener. but it always coming as a failure results. IabResult returns failure. i added in app products in developer console. can any one help me on this?
here is some of my code,
bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"),
mServiceConn, Context.BIND_AUTO_CREATE);
String base64EncodedPublicKey = "my key";
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.enableDebugLogging(true);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
System.out.println("Not Success");
Log.d("In APP Billing", "Problem setting up In-app Billing: " + result);
return;
} else {
System.out.println("Success");
Log.d(" In APP Billing", "Setting up In-app Billing Success: " + result);
}
List<String> additionalSkuList = new ArrayList<String>();
additionalSkuList.add(SKU_ID);
mHelper.queryInventoryAsync(true, additionalSkuList,
mQueryFinishedListener);
}
});
IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
#Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
// TODO Auto-generated method stub
if (result.isFailure()) {
// handle error
System.out.println("mQueryFinishedListener is Failure"); // i am always getting this
return;
}
System.out.println("mQueryFinishedListener is Success");
Boolean hasPur = inv.hasPurchase(SKU_ID);
if (hasPur) {
System.out.println("Query - - subscribed ");
isSubscribed = true;
} else {
System.out.println("Query - not subscribed ");
isSubscribed = false;
}
System.out.println("Purchase panic:"+inv.getPurchase(SKU_ID));
}
};
any idea why its not working? thanks in advance.
To work with in app subscription i think you will gave to call "launchSubscriptionPurchaseFlow()" method on IabHelper instance you create.
mHelper.launchSubscriptionPurchaseFlow(Activity act, String sku, int requestCode,
OnIabPurchaseFinishedListener listener, String extraData);
OR
mHelper.launchPurchaseFlow(Activity act, String sku, String itemType, int requestCode,
OnIabPurchaseFinishedListener listener, String extraData);
Where itemType = IabHelper.ITEM_TYPE_SUBS
I have a situation where I tested on a test device with the item id: android.test.purchased
And things worked. Then once I changed that string with the real item id, I started getting Item Not Found error when I pressed the buy button.
Also the buy item is a subscription and not a 1-time purchase. Does that make a difference?
I was not sure which part of the code may be at fault, or what may be missing so here is the class for this:
public class SubscribeIntroActivity extends BaseActivity
{
IabHelper mHelper;
// Does the user have the premium upgrade?
boolean isSubscriber = false;
// (arbitrary) request code for the purchase flow

// Subscribe SKU
static final String SUBSCRIBE_SKU = "11";
// Subscribe SKU
static final String TAG = "BILLING";
/** Called when the activity is first created. */

Since this is a subscription I believe you must replace this line:
mHelper.launchPurchaseFlow(SubscribeIntroActivity.this, SUBSCRIBE_SKU, RC_REQUEST, mPurchaseFinishedListener);
with this one:
mHelper.launchSubscriptionPurchaseFlow(SubscribeIntroActivity.this, SUBSCRIBE_SKU, RC_REQUEST, mPurchaseFinishedListener);
At least this is what I use in my code and I have successfully tested it.
I don't think the new in-app billing version 3 currently supports subscriptions. I could be wrong, but I haven't seen any mention of subscriptions in the sample code or documentation, so that could be why you're receiving the the "Item not found" error.
In general, to test purchasing a real item, you need to upload a version of your app to the developer console (but you don't need to publish it), and you have to be using the same (signed) version to test with. It also takes Google Play some time to process/propagate newly added items...so sometimes you unfortunately just need to wait. Check out developer.android.com/training/in-app-billing/test-iab-app.html if you haven't already.
One more thing to know. Purchases doesn't appear immediately. You can test them after 2-3 hours from moment, when you publish it.
Sorry for my English =)
There's a limit of 20 items per request.
Even if you split them in groups of 20 items, it still does
skuList.addAll(inv.getAllOwnedSkus(itemType));
which guarantees an error if number_of_owned_items + number_of_queried_items is greater than 20, in particular, if number_of_owned_items is 21.
Now I understand why someone suggested rewriting the code from scratch from the very beginning.
