keytool是jdk的一部分，它应该是$JAVA_HOME/bin/keytool

KeyTool是JDK的一部分。假设您使用默认设置安装了JDK，您将在$JAVA_HOME/bin中找到它

我自己找到了一个解决方案，如下所示。它工作得很好。

"C:\Program Files\Java\jdk1.6.0_26\bin\keytool.exe" -exportcert -alias
> sociallisting -keystore "D:\keystore\SocialListing"  |
> "C:\cygwin\bin\openssl.exe" sha1 -binary | "C:\cygwin\bin\openssl.exe"
> base64

Few observations while I was getting the same problem (Windows). 1. Shell pipe is important. 2. If you are using OpenSSL or Cygwin, definitely you have to install it. 3. keytool comes with JDK so either you have to point to it in the command or you have cd to the JDK/bin folder (where the exe resides) 4. The debug keystore is typically located at ~/.android/debug.keystore 5. password is "android" whether you -keypass it or type it when prompted. 6. For the alias name, you can open (DO NOT SAVE, just open and close) the keystore file with any editor and read it. 7. MOST IMPORTANT - There is a difference is specifying the keystore path within quotes and without. I got it working by using the keystore path within the double quotes. As remix090378 said and as per the instruction, this command indeed worked - cd C:\Program Files\Java\jdk1.7.0_09\bin

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\userName.android\debug. keystore "密钥存储库" -list -v

考虑添加PATH作为环境变量，并通过cmd访问它。

PATH作为值，C:\Program Files\Java\ jre1.8.0_331\bin作为变量，并通过keytool访问它…

如果你安装了带有Xamarin/移动开发支持的visual studio，你将在这里安装java C:\Program Files\Android\jdk\ microsoft_dist_openjdk_{version}\bin\，就像我的情况一样。
