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?

Answer 1

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

Answer 2

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

Answer 3

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.
