Android Key Hash for Facebook with Cordova

Question

I'm developing a hybrid app with Meteor and Cordova. I'm trying to configure Facebook Connect and got it working on iOS but I'm stuck on android. I cannot seem to find the correct key hash. I always get the message:

Invalid key hash. The key hash ... does not match any stored key hashes.

I already tried to find the correct key hash via the following command:

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

and the standard password "android". I added the resulting key to Facebook but it didn't help. I also tried the tool in the following post. It gave me another key which also did not work. Any ideas?

Meteor uses its own debug keystore when creating an android app via meteor run android-device. The keystore can be found at ~/.meteor/android_bundle/.android/debug.keystore.

Use the following code and the keystore password android for creating your keyhash:

keytool -exportcert -alias androiddebugkey -keystore \
~/.meteor/android_bundle/.android/debug.keystore | openssl sha1 -binary | openssl base64

I went through the same problem and simply had to put the key which was on the error message on FB settings. It worked.

It's not easy to tell apart some characters in that message, such as `L / I, O / 0.` It's not an option to try all combinations. – Luís Brito Jun 21 '17 at 01:35
There is no way to copy/paste from within the native flow. That's the reason for this question in the first place. – Luís Brito Jun 27 '17 at 23:34
I don't get what you mean. In the windows cmd line or linux you get the error and you just haev to copy paste the key – Pierrick Martellière Jul 27 '17 at 00:08

Facebook keyhash works with your application's package name and keystore.

Get your apk signed with a production keystore and use below code to get the facbook keyhash

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

} catch (NoSuchAlgorithmException e) {

}

The facebook Keyhash wil start with '=' equals to sign. For testing purpose you can have both keyhash from debug keystore as well as production keystore.

I'm creating a cordova app like I said, so I wouldn't really know where to put your proposed Java code. There has to be a solution without using custom code? – Ravest Mar 09 '15 at 22:55
The post clearly states that it's a Cordova question, downvoted for not explaining how to put this in a Cordova project, although the code snippet actually worked. – Luís Brito Jun 21 '17 at 01:34
