  • .Call funcation getAppKeyHash from your oncreate methode if you want signed hash then make signed build install signed build and run you will get hash key in dialog then just note it and update it on facebook dev account and comment that function and make another signed APK.
  • Jan 18, 2018  I make a test: put this 'new' key hash in facebook developers key hashes too and tried again and I was able to login successfully. The problem is that key hash is not my key hash generated and saved in the facebook developers app configurations. @saimonventura Does you continues do use this hash key in your facebook developer as production?
  • Trying to create an android app with Facebook integration, I've gotten to the part in the docs where you have to generate a key hash file, it specifies to run the following code keytool -exportcert.

Facebook uses the key hash to authenticate interactions between your app and the Facebook app. If you run apps that use Facebook Login, you need to add your Android development key hash to your Facebook developer profile.

Hash Key Example

This article share the process of generating a key hash for Facebook integration with android using openssl

  1. Download openssl from Google code (If you have a 64 bit machine you must download openssl-0.9.8e X64 not the latest version)
  2. Extract it. create a folder- OpenSSL in C:/ and copy the extracted code here.
  3. Detect debug.keystore file path. If u didn’t find, then do a search in C:/ and use the Path in the command in next step.
  4. Find the keytool path which is in Jre directory. (C:Program FilesJavajre7bin)
  5. Detect your keytool.exe path and go to that dir/ in command prompt and run this command in 1 line

    keytool -exportcert -alias androiddebugkey -keystore “C:Documents and SettingsAdministrator.androiddebug.keystore” – “C:OpenSSLbinopenssl” sha1 -binary ”C:OpenSSLbinopenssl” base64

* that’s all. u will get a key-hash

If you are receiving errors regarding an incorrect key hash when attempting to configure your PhoneGap application for use with the native Facebook Connect plugin (com.phonegap.plugins.facebookconnect) then we hope this guide will help you. Although aimed at PhoneGap applications in particular, the use of keystores and key hashes extends outward to all applications, whether written natively or not.

Any line breaks within the following commands should be ignored and are included for presentation purposes only.

Prerequisites

  • OpenSSL (download here for Windows) (pre-packaged with OS X) – if you are running a 64-bit machine, make sure to grab the 64-bit binaries (x64).
  • keytool – this is packaged as part of Java (download here)
  • PhoneGap Facebook Connect plugin is configured correctly within your app’s codebase. This includes: adding the plugin to your local plugins repository, configuring the plugin with the necessary App ID and App Name values within config.xml, invoking somewhere the Facebook Login prompt from within your app by calling facebookConnectPlugin#login, and declaring the facebookConnectPlugin.js file as a script within index.html.

Generating a Keystore

Where:

<KEYSTORE_NAME> = the name of the keystore file to be generated
<ALIAS_NAME> = the alias of the keystore file

Autocad lt 2010 the key generator 64 bit windows 10. Prompts:

  1. Enter a password for the keystore.
  2. You will be asked for details such as your first and last name, the name of your organisation, etc. These details are not mandatory and can be left as ‘Unknown’, the default value assigned on pressing enter without input.
  3. Enter a password with which to protect the key. Press enter without input to assign the password used for the keystore.

The keystore file <KEYSTORE_NAME> will be saved to the local directory unless you explicitly specified a different location.

Retrieving Key Hash from a Keystore

This command will yield a 28 character hash. Use this in your Facebook app’s Settings page, as seen below:

Submitting Key Hash to a Facebook App

Copy and paste the hash that was generated from the last command and place it within the Key Hashes input:

  • Give the key a title (this can be anything)
  • Input the alias of the keystore as defined by the <ALIAS_NAME> parameter in the above commands
  • Choose the file from your filesystem and press ‘submit key’

Add a Keystore to an App

Generate Hash For File

To connect a keystore to a particular PhoneGap app follow these steps:

Firstly, ‘unlock’ the keystore you want to use:

  • Go to build.phonegap.com/people/edit
  • Click on the Signing Keys tab
  • On the right of the keystore press the yellow padlock
  • Enter the certificate password
  • Enter the keystore password
  • Press ‘submit key

Secondly, add this key to the app:

  • Go to build.phonegap.com/apps and select an app by clicking its name
  • Select a keystore from the dropdown menu next the Android icon (as in the image below)
  • Press Rebuild to compile your app using the new keystore
