Android Facebook key hash — “remote_app_id does not match stored id”

Question

I am trying to implement Facebook log in and then allow the user to post status updates and share details to Facebook through the app. I (think) the user is not successfully able to log into Facebook. Below is the process the user goes through:

• User clicks Login button
• User logs in successfully
• Below window appears to user

• When the user hits the Share button, this error message appears: (#404) remote_app_id does not match stored id

I have gotten the Key Hashes for my debug keystore and release keystore using the below 2 command lines.

Debug Keystore

keytool -exportcert -alias androiddebugkey -keystore C:\Users\lyonsmg\.android\debug.keystore | C:\OpenSSL-Win64\bin\openssl.exe sha1 -binary | C:\OpenSSL-Win64\bin\openssl.exe base64

Release Keystore

keytool -exportcert -alias C:\Users\lyonsmg\matt\_keystores_and_passwords\BibleTriviaLite_keystore -keystore C:\Users\lyonsmg\matt\_keystores_and_passwords\BibleTriviaLite_keystore | C:\OpenSSL-Win64\bin\openssl.exe sha1 -binary | C:\OpenSSL-Win64\bin\openssl.exe

I used android as the password for the debug keystore and my private password for the release keystore. I placed both of the resulting key hashes in Developers Settings on Facebook and also in Facebook App Dashboard. Its the 2 places that the Facebook Android SDK docs tell me to put it.

I have my app_id that is found in the Facebook App Dashboard in my Android Manifest . Below is my Android Manifest and you can see the 2 spots where my app_id is found. You can find it in the code as @string/app_id .

Sorry I wrote so much but I was just trying to cover all my bases and be thorough! My question is, what am I doing wrong? Why is it telling me that my "remote_app_id" does not match my "stored id"?

Answer 1

You're using the same value="@string/app_id" for both com.google.android.gms.games.APP_ID and com.facebook.sdk.ApplicationId .

Your Facebook app ID can't possibly be the same as your Google app ID. You need to get the Facebook app ID from the Facebook App Dashboard.

Answer 2

I was facing the same problem, the hash code that i generated through openssl was wrong i then used this function and it help. Hope it help you all too.

private void printKeyHash() {
    // Add code to print out the key hash
    try {
        PackageInfo info = getPackageManager().getPackageInfo("YOUR PACKAGE 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) {
        Log.e("KeyHash:", e.toString());
    } catch (NoSuchAlgorithmException e) {
        Log.e("KeyHash:", e.toString());
    }
}

Use the hash code that is printed in logs and enjoy. Happy Coding :)
