如何创建一个Facebook密钥散列？ [英] How to create a Facebook key hash?
问题描述
在Facebook的Android的教程中，我们被告知要使用下面的code创建一个关键的哈希值：
In the Facebook android tutorial we are told to use following code to create a key hash:
密钥工具-exportcert -alias androiddebugkey -keystore〜/ .android / debug.keystore | OpenSSL的SHA1 -binary | OpenSSL的BASE64
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
这是确切的code在所有情况下使用？例如，而不是〜/ .android / debug.keystore 要它像 C：/folderone/foldertwo/.android/debug.keystore ？
Is this the exact code to use in all situations? For example instead of ~/.android/debug.keystore should it something like C:/folderone/foldertwo/.android/debug.keystore?
正如你所看到的，我不确定引号是否需要与否，全路径是否需要与否！
As you can see I'm unsure of whether inverted commas are required or not, whether full paths are required or not!
有没有人能够提供一个真实世界的例子？
Is anyone able to provide a real world example?

推荐答案
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) {
}
在您的主要活动:-)这是它为我的作品为Android SDK 3.0
in your main Activity :-) This is the only solution it works for me for Android SDK 3.0
