Uncaught Exception Theme in Facebook Plugin for Phonegap

Question

I am trying to implement a facebook API plugin for Phonegap using the following plugin ... https://github.com/phonegap/phonegap-facebook-plugin/issues/183

I followed the installation guide and I am using Phonegap 2.9.0. For testing, I use the example presented in the project (both a hacker and a simple one). And the application works in Android Jelly Bean 4.2.2

But whenever I tried the login with a facebook example, after clicking OK when authenticating the application, the Android application suddenly stopped.

Any suggestion where I should check?

Here is the LogCat error:

Answer 1

addition to @ umesh25, if you use cordova 2.9, this is already fixed, just comment on the logger that raises a NullPointerException

 277. Log.d(TAG, values.toString()); 

Answer 2

In ConnectPlugin.java, replace:

 try { JSONObject o = new JSONObject(this.fba.facebook.request("/me")); this.fba.userId = o.getString("id"); this.fba.success(getResponse(), this.fba.callbackId); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } 

with the following code:

 Thread t = new Thread(new Runnable() { public void run() { try { JSONObject o = new JSONObject(fba.facebook.request("/me")); fba.userId = o.getString("id"); fba.success(getResponse(), fba.callbackId); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); t.start();
