Question

I am using this simple code from here:

https://developers.facebook.com/docs/mobile/android/build/#sig

public class MainActivity extends Activity {

    Facebook facebook = new Facebook("xxxxxxxxxxxxxx");
    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
    private SharedPreferences mPrefs;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mPrefs = getPreferences(MODE_PRIVATE);
        String access_token = mPrefs.getString("access_token", null);
        long expires = mPrefs.getLong("access_expires", 0);
        if (access_token != null) {
            facebook.setAccessToken(access_token);
        }
        if (expires != 0) {
            facebook.setAccessExpires(expires);
        }

        if (!facebook.isSessionValid()) {
            facebook.authorize(this, new String[] {}, new DialogListener() {
                @Override
                public void onComplete(Bundle values) {
                    SharedPreferences.Editor editor = mPrefs.edit();
                    editor.putString("access_token", facebook.getAccessToken());
                    editor.putLong("access_expires",
                            facebook.getAccessExpires());
                    editor.commit();
                }

                @Override
                public void onFacebookError(FacebookError error) {
                }

                @Override
                public void onError(DialogError e) {
                }

                @Override
                public void onCancel() {
                }
            });
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        facebook.authorizeCallback(requestCode, resultCode, data);
        try {
            JSONObject json = Util.parseJson(facebook.request("me"));
            String facebookID = json.getString("id");
            String firstName = json.getString("first_name");
            String lastName = json.getString("last_name");
            String email = json.getString("email");
            String gender = json.getString("gender");

        } catch (Exception e) {

            //If i click Okay i get Exception saying You need an Active access token to get the current user details
        }

    }
}

got Hash key using this:

which asks for a password (“android”)

and gives me a code like this:

xLYMxxxxxx/0enePexxf4DORUfR8=

and in facebook application my configurations are:

But i get this Error:

and if i press Okay i get the Exception saying You need an Active access token to get the current user details.

I tried all possible solutions given on SOF. But of no use. Please help

Thank You

Answer 1

It seems like you didn’t get your hash key correctly from the terminal.

Try this instead

1. Enable logging by going to the Facebook SDK source Util.java and set ENABLE_LOG to true.
2. Try logging into your app again and you should still see the red error message. Press OK.
3. Go to your logcat and find an entry that looks something like this:

D/Facebook-authorize(24739): Login failed: invalid_key:Android key mismatch. Your key “uk3udeH7vrOGNFH2FJjdJbdWJWI” does not match the allowed keys specified in your application settings. Check your application settings at http://www.facebook.com/developers

Copy and paste that key into your dashboard and try again.
