Robby Pond的回答可以概括为使用JAVA_HOME环境变量，并补偿路径中可能出现的任何空白(如Program Files):

"%JAVA_HOME%\bin\keytool" -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

除了加雷思的

上面的答案，下面的对我有用

只需在Windows命令提示符中输入这些。

确保终端以管理员身份运行

cd C:\Program Files\Android\Android Studio\jre\bin keytool -list -v -keystore "C:\Users\admin.android\debug。Keystore " -alias androiddebugkey -storepass android -keypass android

N:B:这应该在第一次构建后完成，因为密钥只在第一次构建后生成

KEYTOOL在JAVAC SDK中，所以你必须在包含jns JAVAC的目录中找到它

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。

在Windows上

如果你使用Jetbrain的工具箱来管理Android Studio更新，路径是这样的

C:\Users\{USERNAME}\AppData\Local\JetBrains\Toolbox\apps\AndroidStudio\ch-0\202.7486908\jre\bin 

更新后，我必须手动更新/设置此路径为JAVA_HOME (jre文件夹)

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
