#1

hello
Can anyone tell me how can i get signature（google play）,when i use SDKBOX IAP for our owen Verification.

#2

What do you mean by signature? do you mean the receipt for the purchase?

#3 
public void onActivityResult(int requestCode, int resultCode, Intent data) {
		Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + ","
				+ data);
		if (mHelper == null)
			return;

		 purchaseData = data.getStringExtra(IabHelper.RESPONSE_INAPP_PURCHASE_DATA);  
	     dataSignature = data.getStringExtra(IabHelper.RESPONSE_INAPP_SIGNATURE); 
}

like this code in my native googleplay sdk，i can get RESPONSE_INAPP_SIGNATURE，where is RESPONSE_INAPP_SIGNATURE in SDK IAP

This is actually a bother to not have available.

As per google documentation: https://developer.android.com/google/play/billing/billing_integrate.html , together with the response code and data (this is provided by SDKBOX), a signature is also sent in onActivityResult.

A number of libraries used for verifying purchases server-side (such as https://github.com/voltrue2/in-app-purchase) also require the signature from the purchase. It is possible to avoid this by manually using Google’s product api (https://developers.google.com/android-publisher/api-ref/purchases/products/get) which does not require the signature but this is extra development effort for some.

I worked around the issue by using the Product API but I think it’d be very useful to reconsider exposing the signature through SDKBOX’s apis to help others too
