How to generate release key hash or sha1 for Facebook in the android studio, This section of the tutorial explains you how to get Key Hashes for the Android Facebook app. Facebook SDK integration to android requires a key hash configuration.

While integrating Facebook SDK, we need to configure Facebook API console with Key Hash. If a key hash is missing you will get App mis-configured error in the Facebook dashboard.

Download the facebook-android-sdk and configured a new app. In the application, settings enable the “Native android app” and enable for Facebook login and deep linking. It asks for key hashes, and I’m stuck. After spending a generous amount of time, I have found two solutions to get the key hashes.

  • Download OpenSSL from Google code (If you have a 64-bit machine you must download OpenSSL-0.9.8e X64, not the latest version)
  • Extract it. Create a folder- OpenSSL in C: / and copy all files here
  • Find “debug.keystore” file path. Most likely it will be inside “C:Users.android” folder. However, if you still don’t find then perform a search. I am sure you are lucky enough to get it.
  • Find keytool.exe path. It will be inside your java/bin directory. In my system it is under “C:Program FilesJavajdk1.6.0_30bin”
  • Open command prompt (Run-> cmd->start) and go to java /bin folder (cd “C:Program FilesJavajdk1.6.0_30bin” command will do it for you)
  • Now you run the below command.
  • Provide password (android), as when you are prompted. You are done. It will generate you the key-hash

Sorry, what key tool?

If you want to generate a Facebook App ID/Key, go to https://developers.facebook.com/apps and create a Facebook app.

If you want the keytool that you can use to create certificates etc, that is included in the jre.

Explanation for how to deal with the keys and hash here:

Answer：

I used following steps to generate a Key Hash for my app in facebook: (I am using Mac OSX 10.8)

  1. First open a terminal (open a command prompt in windows).
  2. Navigate in the terminal to the directory where your Android debug.keystore is stored.
  3. Mostly it will located under “/Users/user_name/.android/” (In Windows will be C:Documents and Settings.android).

  4. Once you are in the “.android” directory, run the following command.

    keytool -exportcert -alias androiddebugkey -keystore debug.keystore openssl sha1 -binary openssl base64

  5. When it prompts you for a password, type android and hit Enter

  6. Copy the value printed in the terminal that ends with an “=” and
    paste it in the Key Hash field in Facebook. Then click the Save
    Changes button.

Please follow below steps to find debug.keystore and generate key hash for android development at mac.

  1. Open terminal

  2. Type cd ~/.android and hit enter to go to .android directory

  3. If you want to open .android directory in finder, type open . and hit enter. Then .android directory will be opened in finder where you can find debug.keystore. If you do not want to open .android directory and only want to generate key hash, then skip this point and follow #4.

  4. In terminal where you are already in .android directory type

    keytool -exportcert -alias alias_name -keystore sample_keystore.keystore openssl sha1 -binary openssl base64

    and hit enter.

  5. You are asked for password. Enter android as password and hit enter. Then you get key hash ending with “=”

  6. Copy key hash,enter in your facebook app setting page and save changes.

Facebook App Generate Key Hash On Mac

Never did it on Mac before, but here are some advices:

1.You need OpenSSL. Install it. In Windows I just extract zip file, then copy three file include openssl.exe in bin folder to jdk’s bin folder (where keytool is), don’t know how it work on Mac.

2.Copy file keystore what you want to get key hash to jdk’s bin folder. My keystore is debug.keystore (because I’m still in test, I don’t want to use the main keystore).

3.Using command line to go to jdk’s bin folder (In Windows, I just Run -> cmd -> type cd %JAVA_HOME%)

4.Type this command:
keytool -exportcert -alias alias_name -keystore sample_keystore.keystore openssl sha1 -binary openssl base64

Generate Hash Online

In my case (debug.keystore):
keytool -exportcert -alias androiddebugkey -keystore debug.keystore openssl sha1 -binary openssl base64
then enter password for debug.keystore: android (without password, the key hash’s still generated and the same as with password, don’t know why).

Generate Hash Code

You’ll get some string with “=” character at the end. Go to your app setting -> mobile -> fill that key hash (include “=”) to Android key hash.
