Android Facebook SDK:生成发布密钥哈希 [英] Android Facebook SDK: generate release key hash

问题描述

我正在构建一个用户可以使用 Facebook 登录的应用.

我已经创建了如下的哈希键:

尝试{包信息信息 = getPackageManager().getPackageInfo("com.app.package",PackageManager.GET_SIGNATURES);for(签名签名:info.signatures){MessageDigest md = MessageDigest.getInstance("SHA");md.update(signature.toByteArray());Log.d("KeyHash", "KeyHash:"+ Base64.encodeToString(md.digest(),Base64.DEFAULT));Toast.makeText(getApplicationContext(), Base64.encodeToString(md.digest(),Base64.DEFAULT), Toast.LENGTH_LONG).show();}} catch (NameNotFoundException e) {} catch (NoSuchAlgorithmException e) {}

在调试模式下，一切正常.

当我导出项目进行发布时，出现此错误:

无效的密钥散列.密钥散列 ****************** 不匹配任何存储的密钥散列"

我粘贴了 Facebook 开发者仪表板中打印的密钥，但应用程序仍然出现该错误.

我的活动的完整包是com.app.package.views"，我尝试在仪表板中使用这个包(作为 Google Play 包名称)，但没有任何改变.>

我该如何解决?如何生成正确的发布密钥哈希?

解决方案

您是否按照 facebook 提供的步骤创建登录应用程序?

您需要在启动发布密钥库时获得生产密钥哈希":

来自命令行:

keytool -exportcert -alias -keystore |openssl sha1 -binary |openssl base64

并在 facebook 应用页面选项中添加此密钥.

I'm building an app in which users can log in with Facebook.

I've created the hash keys like following:

try {
         PackageInfo info = getPackageManager().getPackageInfo(
         "com.app.package",
         PackageManager.GET_SIGNATURES);
         for (Signature signature : info.signatures) {
         MessageDigest md = MessageDigest.getInstance("SHA");
         md.update(signature.toByteArray());
         Log.d("KeyHash", "KeyHash:"+ Base64.encodeToString(md.digest(),
         Base64.DEFAULT));
         Toast.makeText(getApplicationContext(), Base64.encodeToString(md.digest(),
                 Base64.DEFAULT), Toast.LENGTH_LONG).show();
         }
         } catch (NameNotFoundException e) {

         } catch (NoSuchAlgorithmException e) {

         }

In debug mode, everything works well.

When I export the project for release, it gives this error:

"Invalid key hash. The key hash ****************** does not match any stored key hashes"

I paste the key printed in the Facebook Developer dashboard, but the application still gives me that error.

The complete package of my actvity is "com.app.package.views" and I tried to use this package (as Google Play Package Name) in the dashboard, but nothing changed.

How can I solve it? How can I generate the right release key hash?

解决方案

You followed the steps that facebook provides for the creation of a login application?

You need a 'Production keyhash' obtained starting your release keystore:

From comand line:

keytool -exportcert -alias <RELEASE_KEY_ALIAS> -keystore <RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64

And add this key on facebook app page options.
