Android check if in app purchase was bought before - android

I would like to make an in app purchase in my android app. I use for this the google sample: http://developer.android.com/training/in-app-billing/preparing-iab-app.html#GetSample
I implemented this in my android studio project. In the developer console I set the in app purchase and a gmail address as test account.
on my device (not emulator), I logged in with this test account. I start my app and klick on "Buy Premium" and can finish this process.
now I would like to show a Button (Text "Restore) where the user can restore his in app purchase, IF he / she bought the premium function before.
I have this code:
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.e("-->", "Purchase finished: " + result);
if (mHelper == null) return;
if (result.isFailure()) {
Log.e("-->","Error purchasing: " + result);
return;
}
if (!verifyDeveloperPayload(purchase)) {
Log.e("-->","Error purchasing. Authenticity verification failed.");
return;
}
SharedPreferences prefs = this.getSharedPreferences("xxx", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean("Premium", true);
editor.commit();
Log.e("-->", "Premium: " + prefs.getBoolean("Premium", false));
}
};
If I press on the "buy" button again and I had bought this before, I get this message in log cat:
-->: Purchase finished: IabResult: Unable to buy item (response: 7:Item Already Owned), purchase: null
-->: Error purchasing: IabResult: Unable to buy item (response: 7:Item Already Owned)
My Question is, how can I check if the in app purchase was bought before or not?

mIabHelper.queryInventoryAsync(true, "your_sku", mGotInventoryListener);
// Listener that's called when we finish querying the items and subscriptions we own
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d("PAY", "Query inventory finished.");
// Have we been disposed of in the meantime? If so, quit.
if (mIabHelper == null) return;
Purchase purchase = inventory.getPurchase("your_sku");
if (purchase != null) {
//purchased
}
}

Implementing In-app Billing

I am currently working on in app purchase in my application, when it launches I have always the error code -1003 querying owned items response signature verification failed when I arrive in IabHelper.QueryInventoryFinishedListener method.
I currently uses the example version of Google "Trivial Drive", I guess my signature is correct because I get to buy much when I use android.app.purchassed ...
The key seems correct to me because when I click like to buy a product that tells me that the publisher can not buy the product which is normal in itself (If I put anything I have another error saying the product does not exist). For cons, I have the same error when I put the test product "android.test.purchasse" then I should be able to test with it.
I made a purchase with android.test.purchasse there and I can not reset if you have already succeeded I'm interested.

Have you ever been concerned? I see no way out for this bug help from you will be appreciated.
thank you
You need to create a test account, and put it in the playstore admin page.

mHelper.launchPurchaseFlow start twice

For buy i have code
public void onClick(View v)
{
// FIRST CHECK IF THE USER IS ALREADY A SUBSCRIBER.
mHelper.launchPurchaseFlow(SubscribeIntroActivity.this, SUBSCRIBE_SKU, RC_REQUEST, mPurchaseFinishedListener);
}
public void onClick(View v)
{
// FIRST CHECK IF THE USER IS ALREADY A SUBSCRIBER.
mHelper.launchPurchaseFlow(SubscribeIntroActivity.this, SUBSCRIBE_SKU, RC_REQUEST, mPurchaseFinishedListener);
}
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase);
// if we were disposed of in the meantime, quit.
if (mHelper == null) return;
if (result.isFailure()) {
Log.d(TAG,"Error purchasing: " + result);
return;
}
if (!verifyDeveloperPayload(purchase)) {
Log.d(TAG,"Error purchasing. Authenticity verification failed.");
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.");
Log.d(TAG,"Thank you for upgrading to premium!");
mIsPremium = true;
isShortVersion=false;
DrawIsShortVersion();
}
}
};
Error in LOG IS
Caused by: java.lang.IllegalStateException: Can't start async operation (launchPurchaseFlow) because another async operation(launchPurchaseFlow) is in progress.
when i click button its open buyer dialog and i can buy without any problem, but if i click button dialog is opened, Push BACK hardware button on device (didnt buy) i see first activity with button BUY, push it for buy again and raise error. May be somebody know about this error? what i do wrong?
... added if (mHelper != null) mHelper.flagEndAsync(); before call launchPurchaseFlow, now no errors, but mHelper.flagEndAsync(); kill previos task ?
Can you post your Logs?
In most cases an error occours when an Async PurcaseFlow is running and yout try to run an other Purcase.
what are you doing in your Purcase Listener?
Edit: you have multiple Coices to make that:
First: create a global boolean -> mTaskIsRunning;
private void doBuyProduct(int id){
if(!mTaskIsRunning){
mHelper.launchPurchaseFlow(SubscribeIntroActivity.this, SUBSCRIBE_SKU, RC_REQUEST, mPurchaseFinishedListener);
mTaskIsRunning=true;
}
}
Then in your Listener:
....
mTaskIsRunning=false;
Or you can disable the Buttons while a Task is Running
Same Procedure :
private void doBuyProduct(int id){
disableBuyButtons();
mHelper.launchPurchaseFlow(SubscribeIntroActivity.this, SUBSCRIBE_SKU, RC_REQUEST, mPurchaseFinishedListener);
}
and in the FinishListener:
enableButtons();

Lost purchaseToken for In-App Billing Api

I was integrating Android In-App Billing api. but I lost the purchaseToken as there was a exception thrown somewhere. Now in API 3 I can't re-buy it without consuming the bought product. I can't consume it now as I don't have the purchaseToken? How to retrive it?
Or can I reset the purchase somehow??
You could get it by querying purchases.
Here is an example from Google: http://developer.android.com/google/play/billing/billing_integrate.html#billing-download
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
// Have we been disposed of in the meantime? If so, quit.
if (mHelper == null) return;
// Is it a failure?
if (result.isFailure()) {
complain("Failed to query inventory: " + result);
return;
}
Log.d(TAG, "Query inventory was successful.");
/*
* Check for items we own. Notice that for each purchase, we check
* the developer payload to see if it's correct! See
* verifyDeveloperPayload().
*/
// Do we have the premium upgrade?
Purchase premiumPurchase = inventory.getPurchase(SKU_PREMIUM);
....
//<- here you can consume your purchase
}

Implement Google in-app-billing in existing app

Since one year I develop android apps. I thought it’s time now to do the next step and implement the billing system. Before I implement this new feature in my main app I thought it’s better to test it.
Last week i developed a test app the same app (with v3 billing system) like my main app (without v3 billing system). I published it and installed on my Samsung Note via Google Play. I was being able to buy and to subscribe. And it worked well.
So I deactivated the test app, copied the whole billing methods in my main app, changed the Base64 coded public RSA key and published it.
After installation and start, the app crashed every time. And the reason is only the billing system because the recent version works without the billing system well. Of course I could replace my main app with a new app which do the same like my main app, but I would lose all my user, my statistics and comments until now.
Do you know why my app cannot install the billing system with the RSA key?
Which other reasons could be responsible for this Situation?
what happens in onCreate:
mHelper = new IabHelper(this, base64EncodedPublicKey);
// enable debug logging (for a production application, you should set this to false).
mHelper.enableDebugLogging(false);
// Start setup. This is asynchronous and the specified listener
// will be called once setup completes.
Log.d(TAG, "Starting setup.");
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);
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(mGotInventoryListener);
}
});
and what happens in line 960:
public 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.");
// Purchase premium monthly
Purchase purchase = inventory.getPurchase(Constants.PREMIUM);
if(purchase.getPurchaseState() == Purchase.PURCHASED_SUCCESSFULLY && verifyDeveloperPayload(purchase)){
isPremium = true;
}else{
isPremium = false;
updatePremium(purchase.getPurchaseState());
}
Log.d(TAG, "User " + (isPremium ? "HAS" : "DOES NOT HAVE") + " premium surebets for 32 days.");
Log.d(TAG, "Initial inventory query finished; enabling main UI.");
}
};

In app purchase not fully working

I just wrote a test application to test in app purchases, it's just a test application where you have to press a button and you purchase a "premium" membership that will make that button invisible (this is just a test app)
So after my friend pressed the button he got the payment screen, he paid, but when he got back to the app the button was still there
This is how i start the purchase
// 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);
}
and when the purchase is finished
// 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(), "Failed to purchase", 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(), "You are now premium", duration).show();
Button test = (Button) findViewById(R.id.test);
test.setVisibility(View.INVISIBLE);
// updateUi();
// setWaitScreen(false);
}
}
};
The code was taken from the sample app that was provided by google,i removed the parts i didn't need, maybe i removed something that was needed?
Indeed, you must also copy the onActivityResult method from the example activity into your activity. When you have done this, it should work.
