How do I Build without Eclipse?

• Solution
  • Check the Android Guide

How do I Add a Like Button?

• Problem

  • I am trying to implement like button functionality in my app. Whenever user likes my facebook page, user will get rewards. So i have tried to implement this like button functionality as described here: https://developers.facebook.com/docs/plugins/like-button

• Solution

  • It won't work for native apps because: https://developers.facebook.com/docs/ios/like-button/ is not supported yet. HOWEVER; it can be done with the graph API http://stackoverflow.com/questions/11915269/built-in-like-button-facebook-sdk-3-0 Things you have to take care of are :

  1. Your like button must not be the same (graphically) as the Facebook like button

  2. When you display your page / button you have to call the getLoginStatus method first to know if the current user is connected to its Facebook account. If he is connected then call GET https://graph.facebook.com/me/og.likes?access_token=FB_ACCESS_TOKEN&object=URL_TO_LIKE with the Facebook Access Token returned by the g3. etAccessToken method (if this returns data then style your like button with a red heart for example, a grey heart if the call returns an empty array).

  3. To create a like (when your user clicks on your like button and your like button is a grey heart) do a POST on https://graph.facebook.com/me/og.likes?access_token=FB_ACCESS_TOKEN&object=URL_TO_LIKE

  4. To remove a like (when your user clicks on your like button and your like button is a red heart) do a DELETE on https://graph.facebook.com/LIKE_IDENTIFIER?access_token=FB_ACCESS_TOKEN. The LIKE_IDENTIFIER is returned from steps 2 or 3.

The better way to understand this little "workflow" is to manipulate the Graph API on the og.likes endpoint using the Facebook Graph Explorer tool.

Where is the init API?

• Problem

  • I was using FB.init() and now it's not working.

• Solution

  • You are using an out-dated API. Please check the new API with sample code and sample projects in platforms/ios and platforms/android.

Android

No Reply From Login?

• Problem

  • facebookConnectPlugin.login doesn't call neither success nor faillure methods. - When I'm disconnected from Facebook and don't have the native app, the iframe fallback is blank. Checking on chrome inspector, the elements are set to display: none.

• Solution

  • Copy and paste the following code to print your hash. Add the hash to your Facebook Developer Dashboard.

try {
  PackageInfo info =
  cordova.getActivity().getPackageManager().getPackageInfo("com.goapes.golearn", 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) {

}

Facebook error: Session was closed and was not closed normally

• Problem

  • Receiving the above error and no return from login.

• Solution

  • Your hash is wrong or not updated see No Reply From Login?

My Hash Does Not Work, I am Using Windows

• Problem

  • Windows users have to be careful about openssl-for-windows http://code.google.com/p/openssl-for-windows/downloads/list, the latest version, at least on plataform 64bit, does not generate the correct hash that Facebook needs for android apps.

• Solution

  • Use one of these versions when creating your hash: openssl-0.9.8e_X64.zip or openssl-0.9.8d_X64.rar

You should not use the openssl-0.9.8k_X64.zip.

Jar mismatch! Fix your dependencies

• Problem
  • I get this error:

BUILD FAILED
/usr/local/opt/android-sdk/tools/ant/build.xml:577: Jar mismatch! Fix your dependencies

• Solution
  • You may have duplicate android-support-v4.jar files. Remove android-support-v4.jar from the /libs folder of your project.

Open Fullscreen Dialog in Landscape Orientation

• Problem:

  • In landscape orientation the dialog is too small to use keyboard input

• Solution:

  • One can force the dialog to be displayed fullscreen, providing additional screen space for the dialog

Add this import to facebookConnectPlugin.java

import android.content.res.Configuration;

Change the feed dialog from:

WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(me.cordova.getActivity(), Session.getActiveSession(), paramBundle)).setOnCompleteListener(dialogCallback).build();
feedDialog.show();

to

WebDialog.FeedDialogBuilder feedDialog = (new WebDialog.FeedDialogBuilder(me.cordova.getActivity(), Session.getActiveSession(), paramBundle)).setOnCompleteListener(dialogCallback);
if (cordova.getActivity().getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
	feedDialog.setTheme(android.R.style.Theme_Wallpaper_NoTitleBar_Fullscreen);
}
feedDialog.build().show();

Change the feed dialog from:

WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(me.cordova.getActivity(), Session.getActiveSession(), paramBundle)).setOnCompleteListener(dialogCallback)
	.build();
requestsDialog.show();

to

WebDialog.RequestsDialogBuilder requestsDialog = (new WebDialog.RequestsDialogBuilder(me.cordova.getActivity(), Session.getActiveSession(), paramBundle)).setOnCompleteListener(dialogCallback);
if (cordova.getActivity().getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
	requestsDialog.setTheme(android.R.style.Theme_Wallpaper_NoTitleBar_Fullscreen);
}
requestsDialog.build().show();

iOS

Missing FacebookConnectPlugin

• Problem:
  • CDVPlugin class FacebookConnectPlugin (pluginName: facebookconnectplugin) does not exist.
• Solution:
  1. Open up Xcode
  2. Go to "Build Phases"
  3. Ensure that the following file is added under "Compile Sources":
     • FacebookConnectPlugin.m
  4. Ensure that the following is added under "Link Binary With Libraris":
     • FacebookSDK.framework
     • libsqlite3.dylib
     • Social.framework
     • Accounts.framework
     • Security.framework

Cordova and plugman seems to have some problems adding frameworks etc. when re-installing/upgrading plugins.

Login Always Opens Web Dialog Even Though Native App is Installed

• Problem:
  • Calling the login function always opens the web dialog even though the native app is installed on the device.
• Solution:
  • Switch "deep linking" to ON in the Facebook developer website settings for your application

Login fails with devices running iOS 10

• problem:
  • even if login works properly with older iOS versions, on iOS 10+, error callback is always called
• Solution:
  • Give the iOS application access to the Keychain Sharing capability before building it as instructed in http://stackoverflow.com/questions/38689631/how-to-use-facebook-ios-sdk-on-ios-10.
