如何创建一个Facebook密钥哈希？ [英] How to create a Facebook key hash?

问题描述

keytool -exportcert -alias androiddebugkey - keystore〜/ .android / debug.keystore | openssl sha1 -binary | openssl base64

这是在所有情况下使用的确切代码？例如，而不是〜/ .android / debug.keystore 应该像 C：/folderone/foldertwo/.android/debug.keystore ？

您可以看到我不确定是否需要反转逗号，是否需要完整的路径！

有人能提供真实的例子吗？

解决方案

尝试

  try {
 PackageInfo info = getPackageManager ）.getPackageInfo（com.eatapp，PackageManager.GET_SIGNATURES）; 
（签名签名：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）{
 
} 
  

在你的主要活动:-)这是唯一的解决方案，它适用于Android SDK 3.0

In the Facebook android tutorial we are told to use following code to create a key hash:

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.keystore should it something like 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!

Is anyone able to provide a real world example?

解决方案

try

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
