Key hash not getting verified to login with facebook sdk

Question

I want to use facebook sdk. I have created an app in fb developers console, also created a hash key using

 C:\Program Files (x86)\Java\jre1.8.0_131\bin>keytool -exportcert -alias androiddebugkey -keystore C:\Users\siddhi jambhale\.android\debug.keystore | "C:\Program Files (x86)\openssl-0.9.8k_X64\bin\openssl.exe" sha1 -binary | "C:\Program Files (x86)\openssl-0.9.8k_X64\bin\openssl.exe" base64



Illegal option:  jambhale\.android\debug.keystore

keytool -exportcert [OPTION]...

Exports certificate

Options:

 -rfc                            output in RFC style
 -alias <alias>                  alias name of the entry to process
 -file <filename>                output file name
 -keystore <keystore>            keystore name
 -storepass <arg>                keystore password
 -storetype <storetype>          keystore type
 -providername <providername>    provider name
 -providerclass <providerclass>  provider class name
 -providerarg <arg>              provider argument
 -providerpath <pathlist>        provider classpath
 -v                              verbose output
 -protected                      password through protected mechanism

Use "keytool -help" for all available commands

Above its showing illegal option but got the key, tried to use this key but not working.

As showing illegal option I tried to cut down space between username ie siddhijambhale. And tried the key I got. But this is also not working.

C:\Program Files (x86)\Java\jre1.8.0_131\bin>keytool -exportcert -alias androiddebugkey -keystore C:\Users\siddhijambhale\.android\debug.keystore | "C:\Program Files (x86)\openssl-0.9.8k_X64\bin\openssl.exe" sha1 -binary | "C:\Program Files (x86)\openssl-0.9.8k_X64\bin\openssl.exe" base64

I get this error, and the key shown in the error is different than the key I have got from cmd and which is stored in the fb developers console.

What to do for this?

Please help. Thank you..

run this code in your one of activity...

try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    "YOUR_PACAKGE_NAME", 
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

it will give you keyHash and Add that keyhash in your Facebook A/C.
