Question

我已实施IAP结算。但我得到的问题是在购买产品后，应用程序崩溃了。说错误无效的密钥规范。但付款是成功的。当我浏览网页时，我发现密钥有问题。这是我通过注销跟踪出现错误的代码。

这里我提供了我从市场页面获得的 base64EncodedPublicKey（MIIBI **************等）

   PublicKey key = BillingSecurity.generatePublicKey(base64EncodedPublicKey);
        verified = BillingSecurity.verify(key, signedData, signature);
        if (!verified) {
            Log.w(TAG, "signature does not match data.");
            return null;
        }




 try {
        byte[] decodedKey = Base64.decode(encodedPublicKey);
        KeyFactory keyFactory = KeyFactory.getInstance(KEY_FACTORY_ALGORITHM);
        return keyFactory.generatePublic(new X509EncodedKeySpec(decodedKey));
    } catch (NoSuchAlgorithmException e) {
        throw new RuntimeException(e);
    } catch (InvalidKeySpecException e) {
        Log.e(TAG, "Invalid key specification.");
        throw new IllegalArgumentException(e);
    } catch (Base64DecoderException e) {
        Log.e(TAG, "Base64DecoderException.", e);
        return null;
    } catch (Exception g)
    {
        Log.e(TAG, "Exception generate Public key.", g);
        return null;
    }

注意：我能够收到产品购买详情和应用程序崩溃后。

请在这里帮助我。提前致谢。
