Answer 1

You can use the test SKU's to do testing, as explained here. These are:

• android.test.purchased
• android.test.canceled
• android.test.refunded
• android.test.item_unavailable

These purchases will be successful (at least the android.test.purchased) even in test and debug scenario's, without the need to cancel the purchase.

In the verifyPurchase I changed return false to:

    Log.e(TAG, "Purchase verification failed: missing data.");
    if (BuildConfig.DEBUG) {
            return true;
    }
    return false;           

but you should be aware to use this only in test scenario's.

This will return true, if you have a debug build, and the signature data is missing. Since the BuildConfig.DEBUG will be false in a production build this should be OK. But better is to remove this code after everything is debugged.
