Check Google In app purchase inventory

I am new to the coding and i mostly copy and paste from the google in app billing
Can anyone guide me in what is wrong in the code. Refer this
Android check if in app purchase was bought before
Here is my purchaseActivity
public class PurchaseActivity extends CustomMenu {
tk.myessentialoils.ideasapp.util.IabHelper mHelper;
Button buyButton;
String product1SKU;
Boolean VIP=false;
//String product1SKU = "vip_member";//getResources().getString(R.string.product1SKU);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_purchase);
buyButton = findViewById(R.id.buyButton);
product1SKU = getString(R.string.product1SKU);
mHelper = new tk.myessentialoils.ideasapp.util.IabHelper(this, getString(R.string.billing64basecode));
mHelper.startSetup(new tk.myessentialoils.ideasapp.util.IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(tk.myessentialoils.ideasapp.util.IabResult result) {
if (!result.isSuccess()) {
// Oh no, there was a problem.
Log.d("TAG", "Problem setting up In-app Billing: " + result);
}
// Hooray, IAB is fully set up!
}
});
/*
try {
mHelper.queryInventoryAsync(mGotInventoryListener);
} catch (IabHelper.IabAsyncInProgressException e) {
Log.d("TAG","Error querying inventory. Another async operation in progress.");
}
SharedPreferences.Editor editor = this.getSharedPreferences("Name", MODE_PRIVATE).edit();
Log.d("TAG", "checkVIPStatus: " +VIP);
editor.putBoolean("VIP",VIP);
editor.apply();
*/
}
#Override
public void onDestroy() {
super.onDestroy();
if (mHelper != null) try {
mHelper.dispose();
} catch (tk.myessentialoils.ideasapp.util.IabHelper.IabAsyncInProgressException e) {
e.printStackTrace();
}
mHelper = null;
}
public void buyClick(View view) {
try {
mHelper.launchPurchaseFlow(this, product1SKU, 10001,
mPurchaseFinishedListener, "mypurchasetoken");
} catch (tk.myessentialoils.ideasapp.util.IabHelper.IabAsyncInProgressException e) {
e.printStackTrace();
Toast.makeText(this, "Please set up your google account", Toast.LENGTH_SHORT).show();
}
}
#Override

{
if (!mHelper.handleActivityResult(requestCode,
resultCode, data)) {
super.onActivityResult(requestCode, resultCode, data);
}
}
tk.myessentialoils.ideasapp.util.IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
= new tk.myessentialoils.ideasapp.util.IabHelper.OnIabPurchaseFinishedListener() {

}
else if (purchase.getSku().equals(product1SKU)) {

storeVIP();
}
}
};

SharedPreferences.Editor editor = getSharedPreferences("Name", MODE_PRIVATE).edit();
Log.d("TAG", "checkVIPStatus: " +VIP);
editor.putBoolean("VIP",VIP);
editor.apply();
}
}
Question 1
My purchase activity crashed when I enable the commented code.
mHelper.queryInventoryAsync(mGotInventoryListener);
With the error IAB is not set up.
Can anyone show me what is wrong with this?
Question 2
Should I use queryInventoryAsync or use the method as described in here?
Android: in-app: check if an item has been purchased
Which method is easier or more efficient?

Question 1 answer
Place inside the IAB
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_purchase);
buyButton = findViewById(R.id.buyButton);
product1SKU = getString(R.string.product1SKU);
mHelper = new tk.myessentialoils.ideasapp.util.IabHelper(this, getString(R.string.billing64basecode));
mHelper.startSetup(new tk.myessentialoils.ideasapp.util.IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(tk.myessentialoils.ideasapp.util.IabResult result) {
if (result.isSuccess()) {
Log.d("TAG", "onIabSetupFinished: ");
// Hooray, IAB is fully set up!
try {
mHelper.queryInventoryAsync(mGotInventoryListener);
} catch (IabHelper.IabAsyncInProgressException e) {
Log.d("TAG","Error querying inventory. Another async operation in progress.");
}
}
else {
// Oh no, there was a problem.
Log.d("TAG", "Problem setting up In-app Billing: " + result);
}
}
});
}
Question 2 answer
It depend of type of item we are selling.
For one time transactions, and the item cannot be bought further, i used queryInventoryAsync.

Restore purchases after uninstall

I could manage in my code to perform an in-app-billing. However, if I install the app, and redo the purchase, it does purchase again.
Where is the problem?
Here is the code:
case R.id.action_disable_ads:
try {
mHelper.launchPurchaseFlow(this, ITEM_SKU, 10001,
mPurchaseFinishedListener);
} catch (IabHelper.IabAsyncInProgressException e) {
//e.printStackTrace();
}
return true;
}
return super.onOptionsItemSelected(item);
}
//functions special for in App Billing
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data)
{
if (!mHelper.handleActivityResult(requestCode,
resultCode, data)) {
super.onActivityResult(requestCode, resultCode, data);
}
}
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
= new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result,
Purchase purchase)
{
if (result.isFailure()) {
// Handle error
return;
}
else if (purchase.getSku().equals(ITEM_SKU)) {
consumeItem();
//buyButton.setEnabled(false);
}
}
};
public void consumeItem() {
try {
mHelper.queryInventoryAsync(mReceivedInventoryListener);
} catch (IabHelper.IabAsyncInProgressException e) {
//e.printStackTrace();
}
}
IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener
= new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result,
Inventory inventory) {
if (result.isFailure()) {
// Handle failure
} else {
try {
mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU),
mConsumeFinishedListener);
} catch (IabHelper.IabAsyncInProgressException e) {
//e.printStackTrace();
}
}
}
};
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =
new IabHelper.OnConsumeFinishedListener() {
public void onConsumeFinished(Purchase purchase,
IabResult result) {
if (result.isSuccess()) {
//first save purchase state
SharedPreferences settings = getPreferences(0);
SharedPreferences.Editor settingsEditor = settings.edit();
settingsEditor.putString("adfree", "purchased");
settingsEditor.apply();
//then, hide the disable ads button
MenuItem disableAds = mainMenu.findItem(R.id.action_disable_ads);
disableAds.setVisible(false);
//then display a message that the transaction is successful
Toast.makeText(getApplicationContext(), "AdFree bundle purchased successfully!", Toast.LENGTH_SHORT).show();
//then change the state of ad-free bundle for current session:
adFreeBundle = "purchased";
//then disable ads
interstitialAd = null;
mAdView.setVisibility(View.GONE);
} else {
//display an error message that the transaction was not successful
AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
builder.setTitle("TRANSACTION FAILED!");
builder.setMessage("Unfortunately, the transaction was unsuccessful!");
builder.setPositiveButton("CLOSE", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do nothing but close the dialog
dialog.dismiss();
}
});
final AlertDialog alert = builder.create();
alert.setOnShowListener(new DialogInterface.OnShowListener() {
#Override
public void onShow(DialogInterface arg0) {
alert.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.parseColor("#000000"));
}
});
alert.show();
}
}
};
#Override
public void onDestroy() {
super.onDestroy();
if (mHelper != null) try {
mHelper.dispose();
} catch (IabHelper.IabAsyncInProgressException e) {
//e.printStackTrace();
}
mHelper = null;
}
The process of in-app-billing functioned just fine. However, I would be happy to try to get the purchased item upon reinstalling the app.

This is because you are consuming the purchase, and setting a flag in sharedPreferences.
Don't do this anyone can change the sharedPreferences using the right tools.
When you uninstall your app your sharedPreferences will reset and you will lose your 'purchase'.
Because you consume the item, in the 2nd try your inventory won't have the right SKU available, this is why you are prompt to buy again.
If you make the buy button always visible you will be asked to pay every click.
To fix this
Don't consume the item, and the most important thing don't set any flag in sharedPreferences. this also apply's to sql databases.
Consuming is not meant to be used in a non-consumable item, this is your case since you are charging the user to remove the ads, if you try to consume this your users won't be very happy
When your app starts check your inventory if your inventory has the right SKU then give the user the product.
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
#Override
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
return;
}
// Have we been disposed of in the meantime? If so, quit.
if (mHelper == null) return;
// IAB is fully set up. Now, let's get an inventory of stuff we own.
Log.d(TAG, "Setup successful. Querying inventory.");
try {
mHelper.queryInventoryAsync(new IabHelper.QueryInventoryFinishedListener() {
#Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
handleInventory(result, inv);
}
});
} catch (IabHelper.IabAsyncInProgressException e) {
complain("Error querying inventory. Another async operation in progress.");
e.printStackTrace();
}
}
});
public void handleInventory(IabResult result, Inventory inventory) {
if (mHelper == null) return;
// Is it a failure?
if (result.isFailure()) {
return;
}
Log.d(TAG, "Query inventory was successful.");
Purchase premiumPurchase = inventory.getPurchase(YOUR SKU);
//verify Developer Payload here, it's recommended but not mandatory.
//mIsPremium = (premiumPurchase != null && verifyDeveloperPayload(premiumPurchase));
mIsPremium = premiumPurchase != null;
if (mIsPremium) {
//Enable feature
}else{
//Disable feature
}

Android: Consume a product after purchase (in-app billing)

I have some problems with in app billing, I wanted to create an product inside the app that can be bought several times. But google made the in app billing in a way that a product first must be consumed before you can buy it again. I tried it with the following code:
public class HomeFragment extends Fragment {
private WebView homesite;
private String homeTabUrl;
private ProgressBar pBar;
private Bundle webViewBundle;
private Boolean buddyProfile = false;
private Boolean buddyProfile2 = false;

IabResult: Error refreshing inventory (querying owned items)

I am setting up the Inn-App billing from Google play in my LibGDX based Android app.
Scenario : I have bought the test product "android.test.purchased" successfully and I have not Consumed it. I have not consumed it because it can be bought only once and I have disabled the buy button for that test product. Till this everything is fine.
Issue : Now when I re open the again for 2nd time. I got an alert saying that "Failed to query inventory: IabResult: Error refreshing inventory (querying owned items). (response: -1003:Purchase signature verification failed".
Question :
I expect my product can be bought only once and hence I have not consumed it. Will that be a problem while querying for the inventory in onCreate().
mHelper.queryInventoryAsync(mGotInventoryListener);
Code
private void iabSetup() {
// load game data

Android In app Billing V3 doesn't work

I'm going to implement the Android In-App Billing V3 using IabHelper (trivialdrivesample).
I made the game with cocos2d-x.
In the google developer console there are already ten in-app products.
They almost work well, But some of the items don't work. There is no shown the In-App bundle activity.
I don't know why some work well, some don't work.
It is very strange.
Here is some my code block.
