Android in app purchase: Signature verification failed

Question

I have tried for several days to solve this problem, using the Dungeons demo code that comes with the SDK. I\'ve tried to Google for an answer but can\'t find one.

For Cordova and Hybrid apps you need to use this.iap.subscribe(this.productId) method to subscription InAppPurchase.

Following are the code working fine for me:

 getProdutIAP() {
        this.navCtrl.push('subscribeDialogPage');
        this.iap
            .getProducts(['productID1']).then((products: any) => {
                this.buy(products);
            })
            .catch((err) => {
                console.log(JSON.stringify(err));
                alert('Finished Purchase' + JSON.stringify(err));
                console.log(err);
            });
    }

    buy(products: any) {
        // this.getProdutIAP();
        // alert(products[0].productId);
        this.iap.subscribe(products[0].productId).then((buydata: any) => {
            alert('buy Purchase' + JSON.stringify(buydata));
            // this.sub();
        }).catch((err) => {
            // this.navCtrl.push('subscribeDialogPage');
            alert('buyError' + JSON.stringify(err));
        });
    }

    sub() {
        this.platform.ready().then(() => {
            this.iap
                .subscribe(this.productId)
                .then((data) => {
                    console.log('subscribe Purchase' + JSON.stringify(data));
                    alert('subscribe Purchase' + JSON.stringify(data));
                    this.getReceipt();
                }).catch((err) => {
                    this.getReceipt();
                    alert('subscribeError' + JSON.stringify(err));
                    console.log(err);
                });
        })
    }
