How to play IMA ads on Chromecast from sender app ( Android )

Hi everyone just wondering if anyone knew what we need to do to play IMA ads on chrome cast from a sender app,
From what I understand reading the docs the only way to play it is to send a message to the chromecast receiver with the pubads URL:
private void loadMedia(MediaInfo mediaInfo, Boolean autoplay) {
try {
Log.d(TAG, "loading media");
mRemoteMediaPlayer.load(sApiClient, mediaInfo, autoplay)
.setResultCallback(new ResultCallback<RemoteMediaPlayer.MediaChannelResult>() {
#Override
public void onResult(RemoteMediaPlayer.MediaChannelResult result) {
if (result.getStatus().isSuccess()) {
boolean adStarted = mVideoPlayerController.hasAdStarted();
if (mVideoFragment.isVmap() || !adStarted) {
sendMessage("requestAd," + mAdTagUrl + ","
+ mVideoPlayerController.getCurrentContentTime());
} else {
sendMessage("seek,"
+ mVideoPlayerController.getCurrentContentTime());
}
} else {
Log.e(TAG, "Error loading Media : "
+ result.getStatus().getStatusCode());
}
FYI : the mAdTagUrl is the 'pubads' link
Ex pubs link :
https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/single_ad_samples&ciu_szs=300x250&impl=s&gdfp_req=1&env=vp&output=vast&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ct%3Dskippablelinear&correlator=

Incase anyone was looking for the answer :
it's actually in the AdBreak Clip Info Builder -> setVastAdsRequest() Method.
Pass in the 'pubads' link to this method , and you're good to go.

Know when a suscription was cancelled - Play Billing 1.0

I'm using this tuto to integrate Play Billing Library to my app: http://www.androidrey.com/implement-play-billing-library-in-android-application/ and all works good ... well, not at all. I have problems to know when a suscription was cancelled, I tested all the methods to find a resultCode or something to know this state, but have a method that I could not implement. Could be this the problem?
class: BillingManager.java
public void queryPurchases() {
Runnable queryToExecute = new Runnable() {
#Override
public void run() {
long time = System.currentTimeMillis();
Purchase.PurchasesResult purchasesResult = billingClient.queryPurchases(BillingClient.SkuType.INAPP);
if (areSubscriptionsSupported()) {
Purchase.PurchasesResult subscriptionResult
= billingClient.queryPurchases(BillingClient.SkuType.SUBS);
System.out.println("QUERY 0");
if (subscriptionResult.getResponseCode() == BillingClient.BillingResponse.OK) {
purchasesResult.getPurchasesList().addAll(
subscriptionResult.getPurchasesList());
System.out.println("QUERY 1");
} else {
// Handle any error response codes.
}
} else if (purchasesResult.getResponseCode() == BillingClient.BillingResponse.OK) {
// Skip subscription purchases query as they are not supported.
System.out.println("QUERY 2");
} else {
// Handle any other error response codes.
System.out.println("QUERY 3");
}
onQueryPurchasesFinished(purchasesResult);
System.out.println("QUERY RESULT "+ purchasesResult);
}
};
executeServiceRequest(queryToExecute);
}
private void onQueryPurchasesFinished(Purchase.PurchasesResult result) {
// Have we been disposed of in the meantime? If so, or bad result code, then quit
if (billingClient == null || result.getResponseCode() != BillingClient.BillingResponse.OK) {
Log.w(TAG, "Billing client was null or result code (" + result.getResponseCode()
+ ") was bad – quitting");
return;
}
Log.d(TAG, "Query inventory was successful.");
// Update the UI and purchases inventory with new list of purchases
// mPurchases.clear();
onPurchasesUpdated(BillingClient.BillingResponse.OK, result.getPurchasesList());
}
public boolean areSubscriptionsSupported() {
int responseCode = billingClient.isFeatureSupported(BillingClient.FeatureType.SUBSCRIPTIONS);
if (responseCode != BillingClient.BillingResponse.OK) {
Log.w(TAG, "areSubscriptionsSupported() got an error response: " + responseCode);
}
return responseCode == BillingClient.BillingResponse.OK;
}
It is supposed to be called here: MyBillingUpdateListener.java
public class MyBillingUpdateListener implements BillingManager.BillingUpdatesListener {
//final BillingManager billingManager = new BillingManager(,this );
#Override
public void onBillingClientSetupFinished() {
//billingManager.queryPurchases(); THIS IS WHAT I COULD NOT IMPLEMENT
}
Any help is welcome, thanks!.

Play Billing 1.0 does not have the concept of purchase states (anymore), so there currently is no way to get this information using the Play Billing library.
My understanding is that queryPurchases is supposed to return actual valid purchases only. However, it gets the information from a long living cache and you have no way of updating it manually.
onBillingClientSetupFinished is completely unrelated.
Here is an active discussion on the subject: https://github.com/googlesamples/android-play-billing/issues/122

Provoke conflict when using Android Snapshots (Game Play Services)

I have implemented functions to save and load snapshots using the Game API from Google Play Services. The next step I am working on is to handle conflicts when there is more then one snapshot. And here comes the problem.
In my understanding a conflict should occure when doing the following:
Save a snapshot after making game progress
Sign out (Google Play Services)
Delete all app data
Start game again and make some progress
Sign in (Google Play Services)
Save a new snapshop
Load snapshop
Unfortunately in my case no conflict occures. Instead the current game progress is being saved (step 6) and loading (step 7) just returns this snapshop. There is no indicator that snapshot (step 1) was overwritten - resulting in loosing game progress.
Code for saving:
private void executeSave() {
AsyncTask.execute(new Runnable() {
#Override
public void run() {
GoogleApiClient googleApiClient = App.getGoogleApiHelper().getmGoogleApiClient();
Snapshots.OpenSnapshotResult openResult = Games.Snapshots.open(googleApiClient, getSavegameFilename(), true).await();
Status resultStatus = openResult.getStatus();
Log.d(TAG, "openstatus is: " + resultStatus.getStatusMessage());
if(resultStatus.isSuccess()) {
byte[] localSavegame = getPersistingManager().readBytes();
if(localSavegame != null) {
Log.d(TAG, "Going to save:" + getPersistingManager().read());
createSnapshot(openResult.getSnapshot(), localSavegame).await();
}
}
}
});
}
private PendingResult<Snapshots.CommitSnapshotResult> createSnapshot(Snapshot snapshot, byte[] data) {
GoogleApiClient googleApiClient = App.getGoogleApiHelper().getmGoogleApiClient();
snapshot.getSnapshotContents().writeBytes(data);
SnapshotMetadataChange metadataChange = new SnapshotMetadataChange.Builder().build();
return Games.Snapshots.commitAndClose(googleApiClient, snapshot, metadataChange);
}
Code for loading:
private void executeLoad() {
AsyncTask.execute(new Runnable() {
#Override
public void run() {
GoogleApiClient googleApiClient = App.getGoogleApiHelper().getmGoogleApiClient();
Snapshots.OpenSnapshotResult result = Games.Snapshots.open(googleApiClient, getSavegameFilename(), true).await();
processResult(result, 0);
}
});
}
private void processResult(Snapshots.OpenSnapshotResult result, int retryCount) {
Status resultStatus = result.getStatus();
retryCount++;
if(resultStatus.isSuccess()) {
Log.d(TAG, "No conflict, thats great!");
handleSuccess(result);
} else if (resultStatus.getStatusCode() == GamesStatusCodes.STATUS_SNAPSHOT_CONFLICT) {
Log.d(TAG, "Aww... a conflict!");
handleConflict(result, retryCount);
} else {
Log.e(TAG, "Error while getting savegame, status message: " + resultStatus.getStatusMessage());
}
}
When performing the steps from above this is happening:
1) Save a snapshot after making game progress
absRemotePersistMgmt: openstatus is: STATUS_OK
absRemotePersistMgmt: Going to save:{"solvedQuestions":{"1":[],"2":[1]}}
6) Save a new snapshot
absRemotePersistMgmt: openstatus is: STATUS_OK
absRemotePersistMgmt: Going to save:{"solvedQuestions":{"1":[1,2],"2":[]}}
7) Load snapshop
absRemotePersistMgmt: No conflict, thats great!

Error You Already Own This Item

I have a new android app in which I am adding in-app billing and I am tearing my hair out with frustration.
I have uploaded a signed APK and published to alpha. I created a set of in-app products and activated them all. I have created a new gmail account and defined them as a tester for the app on the app apk page.
I have factory reset my android phone and initialised it with the new gmail account. I have entered the /apps/testing link in to chrome and signed up as a tester. I then downloaded and installed my app. Inside my app I asked for the in app products that were available and was shown the set i created above. I selected one to buy and went through the following purchase process.
1. Screen shows product to be purchased and price and requests press continue which i do
2. Screen shows payment methods and I select redeem code
3. Screen shows redeem your code and I enter one of the promotion codes I set up in the developer console earlier (not mentioned above - sorry) and press redeem
4. Screen shows product again, this time with price crossed out and offers option to add item which I select (very strange being asked to add again buy hey ho)
5. Screen shows item added
6. After a fews seconds screen shows Error you already own this item.
How can this be, this user did not exist before ten minutes ago and has only used this app once as described above.
I have seen many questions in stack overflow and elsewhere similar to this and tried everything, clearing google play store cache, clearing google play store data etc. This sequence described above is my latest attempt with a completely clean user on a completely clean phone.
I could upload my app code used but that misses the point, which is how can this gmail account already own an item when this gmail account have never purchased anything before from anyone. Surely this is a bug.
All clues very welcome as to how to proceed. Code now added, note this is a hybrid android app, with the user purchase decisions code in javascript/html and the in app actions in the wrapper code below
private void processCommand(JSONObject commandJSON) throws JSONException
{
String command = commandJSON.getString("method");
if ("GetInAppProducts".equals(command))
{
Log.d(TAG, "Querying Inventory");
InAppPurchaseSkuString = null ; // clear the purchased sku. Note this is tested in mConsumeFinishedListener
mHelper.queryInventoryAsync(true, itemSkus, new IabHelper.QueryInventoryFinishedListener()
{
#Override
public void onQueryInventoryFinished(IabResult iabResult, Inventory inventory)
{
InventoryRecord = inventory ;
if (iabResult.isFailure())
{
Log.d(TAG, "Query inventory failed");

}
else

Log.d(TAG, "Query inventory was successful.");
InventoryCheckCount = 0 ; // seems that we cannot just fire off a whole lot of these checks at the same time, so do them in sequence
if (itemSkus.size()>0) { CheckForOwnedItems (); } else { SendEndItemsToApp (); }
}
}
});
}
else if ("BuyInAppProduct".equals(command))
{
JSONArray params = commandJSON.getJSONArray("parameters");
InAppPurchaseSkuString = params.getString(0);
Log.d(TAG, "User decision to purchase " + InAppPurchaseSkuString);
mHelper.launchPurchaseFlow( MainActivity.this, InAppPurchaseSkuString, InAppPurchaseActivityCode, mPurchaseFinishedListener, "mypurchasetoken"); // consider putting the user email address in the last field - need to get from app
};
}//end of ProcessCommand
public void CheckForOwnedItems ()
{
Log.d(TAG, "Pre Purchase Inventory Processing Started");

public void SendItemToApp ()
{
String sku = itemSkus.get(InventoryCheckCount);
String priceString = InventoryRecord.getSkuDetails(sku).getPrice().replaceAll("[^\\d.]+", ""); // RegExp removes all characters except digits and periods
String infoString = "InAppProductDetails('" + sku + "','" + "dummy" + "','" + priceString + "');"; // dummy is a placeholder for product description which is not (yet?) used in the app
Log.d(TAG, infoString);
mWebView.evaluateJavascript (infoString, new ValueCallback<String>()
{
#Override

}
}
);
}

Log.d(TAG, endString);
mWebView.evaluateJavascript(endString, new ValueCallback<String>()
{
#Override

{
//Log.d(TAG,"Returned from InAppProductsEnd:");
}
}
);
}
public void consumeItem()
{
Log.d(TAG,"Pre Purchase Inventory Query Started");
String sku = itemSkus.get(InventoryCheckCount);
mHelper.consumeAsync(InventoryRecord.getPurchase(sku), mConsumeFinishedListener);
}
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener()
{
public void onConsumeFinished (Purchase purchase, IabResult result)
{
if (result.isSuccess())
{
Log.d(TAG, "Pre Purchase Consume Item Completed");
SendItemToApp ();
InventoryCheckCount++;
if (InventoryCheckCount < itemSkus.size()) { CheckForOwnedItems (); } else { SendEndItemsToApp (); }
}
else
{
Log.d(TAG,"Pre Purchase Consume Item Failed");
}
}
};
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener()
{
public void onIabPurchaseFinished (IabResult result, Purchase purchase)
{
if (result.isFailure())
{
Log.d(TAG,"Purchase Scenario Failed");
}
else if (purchase.getSku().equals(InAppPurchaseSkuString))
{
Log.d(TAG,"Purchase Scenario Completed");
String evalString = "InAppProductPurchased('" + InAppPurchaseSkuString + "');";
Log.d(TAG, evalString);
mWebView.evaluateJavascript (evalString, new ValueCallback<String>()
{
#Override
public void onReceiveValue(String s)
{
Log.d(TAG, "Returned from InAppProductPurchased:");
}
}
);
}
}
};

I have found that this error does not occur when using paypal (i.e. real money) to make the purchase, so I believe that this "Error you already own this item" message is in some way connected to using a promotion code for the test. And (so far) my paypal account has not been charged (as I am a resgistered tester for the app).

How to debug in-app billing on Android 4.1 and 4.2?

New to Android dev and I have this very annoying, and familiar problem.
Short version: how can I test my app on multiple physical devices w/o buying them? Specifically, I'm trying to test on 4.1 and 4.2 running devices. I can't use an emulator because this involves in-app billing.
Long version:
Today, I got a crash report from a user (android version = 4.2, on device = A1-811 (mango)).
The issue is: IAB helper is not set up. Can't perform operation: queryInventory . I tested the app on 4.3, 5.0, 5.1 and it's fine.
I KNOW that the actual crash happened because I wasn't quitting when I was checking for (!result.isSuccess()) in mhelper.startSetup().
My question is, how do I solve the underlying issue of IabHelper not being set up?! I don't have access to Android 4.2 device...
MY CODE:
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener () {
public void onIabPurchaseFinished (IabResult result, Purchase purchase) {
if (mHelper == null)
return;
if (result.isFailure ()) {
Log.d (PURCHASE_TAG, "Google's response is a failure.");
} else {
Log.d (PURCHASE_TAG, "Response is successful. purchase.getSKU = " + purchase.getSku ());
premium = true;
}
}
};
IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener () {
public void onQueryInventoryFinished (IabResult result, Inventory inventory) {
Log.d (PURCHASE_TAG, "Processing Google's response.");
// Check if user has existing purchase.
if (result.isFailure ()) {
Log.d (PURCHASE_TAG, "Google's response is a failure. Response = ");
} else {
Log.d (PURCHASE_TAG, "Google's response is success! getPurchase() = " + inventory.getPurchase (THE_SKU));
if (inventory.getPurchase (THE_SKU) == null) {
premium = false;
} else {
premium = inventory.getPurchase (THE_SKU).getSku ().equals (THE_SKU);
}
}
// Show price if user is not premium, thank you note if the user is premium
if (premium == true) {
Log.d (PURCHASE_TAG, "3 premium = " + premium);
priceView.setText ("Thank you for the purchase!");
} else {
if (inventory != null) {
String pro_price = inventory.getSkuDetails (THE_SKU).getPrice ();
priceView.setText ("" + pro_price);
}
}
}
};
private void startPurchaseQuery () {
String base64EncodedPublicKey = "the key is generated ...";
mHelper = new IabHelper (this, base64EncodedPublicKey);
Log.d (PURCHASE_TAG, "Purchase query started.");
mHelper.startSetup (new IabHelper.OnIabSetupFinishedListener () {
public void onIabSetupFinished (IabResult result) {
Log.d (PURCHASE_TAG, "IabHelper Setup successful. Querying inventory.");
if (!result.isSuccess ()) {
Log.d (PURCHASE_TAG, "Error with IabHelper setup.");
return;
}
if (mHelper == null) return;
// IAB is fully set up. Now, let's get an inventory of stuff we own.
// Build the SKU list
List<String> additionalSkuList;
additionalSkuList = new ArrayList<String> ();
additionalSkuList.add (THE_SKU);
// Make the query
mHelper.queryInventoryAsync (true, additionalSkuList, mQueryFinishedListener);
Log.d (PURCHASE_TAG, "Query finished. Premium status = " + premium);
}
});
}
#Override
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
Log.d (PURCHASE_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 (PURCHASE_TAG, "onActivityResult handled by IABUtil.");
}
}
#Override
public void onDestroy () {
super.onDestroy ();
if (mHelper != null) mHelper.dispose ();
mHelper = null;
}

Answer from comments above
It's better to catch the error and patch own code first. Trying to reproduce exact issue why was IAB not set up may not be possible, because of all kinds of modifications user can do on his device (could be bug with specific version of distro user is running, which is almost impossible to find out, or similar). As you suggested, using Analytics to find out how many users have this issue is good approach.
To answer original question, you can create Alpha or Beta versions in Developer Console and invite users with specific versions of Android you'd like to target into testing group. This was you could test issues and crashes directly from Dev. Console even when not directly being owner of the device.
