I Can't Find the Android Keytool

How to find Keytool for android app

In windows:

Navigate to you JRE folder in Windows File Explorer - to the directory
with the keytool.exe in the JDK -> bin folder. Mine is in C:\Program Files\Java\jre1.8.0_91\bin but try browsing to the Java folder and
see what version you have and change the path accordingly.
Right click on the mouse while pressing shift key on your keyboard.
Click on Open command window here.

To get the debug certificate fingerprint enter in the command window this:

keytool -exportcert -list -v -alias androiddebugkey -keystore  %USERPROFILE%\.android\debug.keystore

The keytool utility prompts you to enter a password for the keystore. The default password for the debug keystore is android (or no password, just hit enter). The keytool then prints the fingerprint to the terminal. For example:
```
Certificate fingerprint: SHA1: DA:39:A3:EE:5E:6B:4B:0D:32:55:BF:EF:95:60:18:90:AF:D8:07:09
```

I can’t find the Android keytool

keytool comes with the Java SDK. You should find it in the directory that contains javac, etc.

How can I find and run the keytool

I found a solution by myself as below quote. It works fine.

"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

not able to locate keytool on my mac to sign my apk file

Make sure you have cd'd into the android-sdk/platform-tools directory (where the keytool will [most likely] reside). The command won't be found if you aren't in the keytool-containing directory.

Keystore file doesn't exist

You said you are running the command from...

/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin

Is your keystore file in that directory as well? If not then you need to specify the path to the keystore file, e.g.

keytool -list -v -keystore ~/somefolder/mystore.keystore

The keystore used should be the one used to sign the app. For Xamarin debug builds this will be the debug keystore located at /Users/[USERNAME]/.local/share/Xamarin/Mono\ for\ Android/debug.keystore. The command on OSX for this would be...

keytool -list -v -keystore /Users/[USERNAME]/.local/share/Xamarin/Mono\ for\ Android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Or on Windows 7

keytool -list -v -keystore C:\Users\[USERNAME]\AppData\Local\Xamarin\Mono for Android\debug.keystore -alias androiddebugkey -storepass android -keypass android

ERROR:'keytool' is not recognized as an internal or external command, operable program or batch file

Check that the directory the keytool executable is in is on your %PATH% environment variable.

For example, on my Windows 7 machine, it is in
C:\Program Files (x86)\Java\jre6\bin, and my %PATH% variable looks like C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files (x86)\Java\jre6\bin;C:\WINDOWS\System32\WindowsPowerShell\v1.0\ (and many other entries)

cannot find keytool on a mac

If you are using Eclipse under Mac OS X you just need to

Select File -> Export -> select Android -> Export Android Application -> click next -> select your project -> click next -> here you just chose Create new keystore

Android - in which directory is the keytool tool

Use this to get your MD5 fingerprint :
change directory to : C:\Program Files(x86)\Java\JDK folder\bin
and then execute
keytool.exe -list -alias androiddebugkey -keystore "C:\Users\.android\debug.keystore" -storepass android -keypass android
