当我尝试获取订阅时，出现以下错误：

签名认证失败。签名与数据不匹配。应用内计费警告：购买签名验证失败。不添加项目。

我的代码是：

String base64EncodedPublicKey = MY_KEY;

        // compute your public key and store it in base64EncodedPublicKey
        mHelper = new IabHelper(this, base64EncodedPublicKey);

        mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
            public void onIabSetupFinished(IabResult result) {
                if (!result.isSuccess()) {
                    // Oh noes, there was a problem.
                    MyDialogFragment alertDialog_generalError = MyDialogFragment.newInstance(getString(R.string.dialog_alert),getString(R.string.error_general));
                    alertDialog_generalError.show(getSupportFragmentManager(), DIALOG_GENERALERROR);
                } //End if   
                mHelper.queryInventoryAsync(mGotInventoryListener);
            }
        });

            // handle error
            MyDialogFragment alertDialog_generalError = MyDialogFragment.newInstance(getString(R.string.dialog_alert),getString(R.string.error_general));
            alertDialog_generalError.show(getSupportFragmentManager(), DIALOG_GENERALERROR);
            return;
        }//End if
        String premiumPrice = inventory.getSkuDetails(SKU_PREMIUM).getPrice();
        btnPrice.setText(getResources().getString(R.string.btn_suscription) + " " + premiumPrice);

    }else{

    }//End if-else
}

我从控制台开发人员那里获得了 base64EncodedPublicKey，并使用导出向导签署了我的项目。

如果您曾经使用其中一个测试 SKU ( android.test.purchased...) 完成购买流程，则可能会发生此错误。这些购买不是真实的，因此它们没有签名，但它们是您尝试对 IAB 执行任何操作（例如查询库存）时返回的结果的一部分。不幸的是，一旦结果中的某些内容无法验证这些虚假购买会做什么，IAB 就会退出。

有两种方法可以解决这个问题。首先，让验证在测试中总是通过。最安全的方法是更改​​为仅verifyPurchase在IABUtils>Security调试版本时返回 true。

public static boolean verifyPurchase(String base64PublicKey, String signedData, String signature) {
    if (BuildConfig.DEBUG) {
        return true;
    }
    if (TextUtils.isEmpty(signedData) || TextUtils.isEmpty(base64PublicKey) ||
            TextUtils.isEmpty(signature)) {
        Log.e(TAG, "Purchase verification failed: missing data.");
        return false;
    }

    PublicKey key = Security.generatePublicKey(base64PublicKey);
    return Security.verify(key, signedData, signature);
}

解决此问题的第二种方法是不对这些虚假购买进行验证。更好的是：也只能在调试版本上执行此操作。一种方法是更改​​签名verifyPurchase以接受 SKU 并将其用作检查的一部分。然后，您必须更改 IabHelper 以使用此额外参数。

public static boolean verifyPurchase(String base64PublicKey, String signedData, String signature, String sku) {
    if (BuildConfig.DEBUG) {
        if (skuMatchesTestingSku(sku)) {
            return true;
        }
    }

    ...
}

private static boolean skuMatchesTestingSku(String sku) {
    return sku.equals("android.test.purchased") ||
            sku.equals("android.test.canceled") ||
            sku.equals("android.test.refunded") ||
            sku.equals("android.test.item_unavailable");
}

这是非常混乱的，但由于应用内计费的实施方式，我们能做的不多。

就我而言，这base64EncodedPublicKey是错误的。

将返回值设置为 true 

public static boolean verifyPurchase(String base64PublicKey, String signedData, String signature) {
    return true;
}

测试后撤消更改
