How to create a Facebook key hash?
提问by Mel
In the Facebook android tutorial we are told to use following code to create a key hash:
在 Facebook android 教程中，我们被告知使用以下代码来创建密钥哈希：
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
Is this the exact code to use in all situations? For example instead of ~/.android/debug.keystoreshould it something like C:/folderone/foldertwo/.android/debug.keystore?
这是在所有情况下使用的确切代码吗？例如，而不是 ~/.android/debug.keystore应该像C:/folderone/foldertwo/.android/debug.keystore?
As you can see I'm unsure of whether inverted commas are required or not, whether full paths are required or not!
如您所见，我不确定是否需要引号，是否需要完整路径！
Is anyone able to provide a real world example?
有没有人能够提供一个真实世界的例子？

try
尝试
try {
PackageInfo info = getPackageManager().getPackageInfo("com.eatapp", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.e("MY KEY HASH:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
in your main Activity :-) This is the only solution it works for me for Android SDK 3.0
在您的主要活动中 :-) 这是适用于我的 Android SDK 3.0 的唯一解决方案

You can create this way
你可以这样创建
keytool -exportcert -alias androiddebugkey -keystore c:\Users\<your windows default user>\.android\debug.keystore | openssl sha1 -binary | openssl base64
Enter keystore password: android
输入密钥库密码：android

public static String printHashKey(Context ctx) {
// Add code to print out the key hash
try {

In eclipse, window-> preferences-> Android-> build-> default debug keystore, copy the path to replace the ~/.android/debug.keystore
在eclipse中，window-> preferences-> Android-> build-> defaultdebugkeystore，复制路径替换~/.android/debug.keystore

When having the error in the log, when trying to login to Facebook, look for something that looks like:
当日志中出现错误时，在尝试登录 Facebook 时，查找如下所示的内容：
Invalid key hash. The key hash *** does not match any stored key hashes. Configure your app key hashes at http://developers.facebook.com/apps/565561836797777
where "***" is the key that you need to use.
其中“***”是您需要使用的密钥。

I had the same problem, I spend a couple of hours to find a solution, but actually the Facebook SDK provides the solution by itself.
我遇到了同样的问题，我花了几个小时来寻找解决方案，但实际上 Facebook SDK 自己提供了解决方案。
in the DialogListener class I modified the onFacebookError method:
在 DialogListener 类中，我修改了 onFacebookError 方法：
@Override
public void onFacebookError(FacebookError error) {
Log.d("myTag",error.getmessage);
}
Execute the app (which was sign with the same key i use for the market), and on LogCat will be a message under this tag with the correct key.
执行应用程序（使用我在市场上使用的相同密钥进行签名），LogCat 上将在此标签下显示一条带有正确密钥的消息。
We had also created a simple project which does all the work, and returns the correct key on an alert-box and on LogCat. You can find it on our blog.
我们还创建了一个简单的项目来完成所有工作，并在警报框和 LogCat 上返回正确的密钥。您可以在我们的博客上找到它。

One brute force option is to just go ahead and try to share something from your app. My app then displays a Facebook page with the key it is trying to match. Then you can just copy this key and put it in your Facebook 'Settings' page on your developer Facebook account.
一种蛮力选择是继续尝试从您的应用程序中分享一些内容。然后，我的应用程序会显示一个 Facebook 页面，其中包含它试图匹配的密钥。然后，您只需复制此密钥并将其放入开发者 Facebook 帐户的 Facebook“设置”页面中即可。
Not ideal, but in a pinch it may be helpful.
不理想，但在紧要关头它可能会有所帮助。

keytool -exportcert -alias androiddebugkey -keystore "debug.keystore path" | openssl sha1 -binary | openssl base64
keytool -exportcert -alias androiddebugkey -keystore "debug.keystore 路径" | openssl sha1 -binary | openssl base64
if you haven't setup environment variables for open ssl and java sdk than put jdk's bin folder path in place of keytool and your openssl path in place of openssl and not to forget to put double quotes for your path
如果您还没有为 open ssl 和 java sdk 设置环境变量，那么将 jdk 的 bin 文件夹路径代替 keytool 并将您的 openssl 路径代替 openssl 并且不要忘记为您的路径加上双引号
ex-"C:\Program Files\Java\jdk1.5.0_11\bin" -exportcert -alias androiddebugkey -keystore "C:\Users\amin.android\debug.keystore" | "F:\openssl\binsha1\openssl.exe" -binary | "F:\openssl\binsha1\openssl.exe" base64
ex-"C:\Program Files\Java\jdk1.5.0_11\bin" -exportcert -alias androiddebugkey -keystore "C:\Users\amin.android\debug.keystore" | "F:\openssl\binsha1\openssl.exe" -binary | "F:\openssl\binsha1\openssl.exe" base64
