how to correctly use AccessGrant to connect to an android socialauth provider

Question

My android app is storing the android socialauth AccessGrant object from a successful socialauth authorization. I'm persisting it in sqlite and am attempting to used that stored AccessGrant object to allow a Service with an AsycTask connect to a provider (facebook, googleplus, etc.) without displaying login screens to the user. Here's the segment of code from within the AsyncTask of the Service...

AccessGrant currentAccessGrant = new AccessGrant(cn.getKey(),cn.getSecret());

currentAccessGrant.setProviderId(cn.getProviderId());
currentAccessGrant.setAttributes(cn.getAttributes());

manager = new SocialAuthManager();

try {                        
  //manager.getSocialAuthConfig().load("C:\\Users\\Blair\\Documents\\GitHub\\App3\\app3\\src\\main\\assets\\oauth_consumer.properties");
  //manager.getSocialAuthConfig().load();
  manager.getSocialAuthConfig();

} catch(Exception e) {
  Log.e(DEBUG_TAG, "SocialAuthConfig.load Exception", e);
}

if (cn.getProviderId().equals("googleplus")) {
  Log.d(DEBUG_TAG, "Setting googleplus");
  //currentAdapter.addProvider(SocialAuthAdapter.Provider.GOOGLEPLUS, R.drawable.googleplus);

  try {
    //provider = AuthProviderFactory.getInstance(currentAccessGrant.getProviderId(), oauth_consumer.properties);
    //provider = AuthProviderFactory.getInstance(currentAccessGrant.getProviderId());
    //provider = AuthProviderFactory.getInstance("googleplus");

    provider = manager.connect(currentAccessGrant);

    //currentAdapter.getCurrentProvider().setAccessGrant(currentAccessGrant);

  } catch(Exception e) {
    Log.e(DEBUG_TAG, "Social AuthProviderFactory Exception",e);
  }
}

This code gave me a "oauth_consumer.properties file is not found in your class path" error...then I added oauth_consumer.properties to the build.gradle file

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile files('libs/socialauth-android-3.0.jar')
    compile files('libs/socialauth-4.3.jar')
    compile files ('src/main/assets/oauth_consumer.properties')
}

This now just produces a NullPointerException no matter which way I attempt to use the AuthManager or AuthProviderFactory.

If there are any android socialauth experts out there, can you please tell me:
- where am I implementing this incorrectly?
- should I be looking for another way of achieving this?
- why the oauth_consumer.properties file isn't found when I try to use the AuthManager or AuthProviderFactory directly, but it is found when using the AuthAdapter in an Activity (as per the socialauth andriod example projects)?

Thanks!

Solved! It definitely was my fault.

For some reason the properties file was not being found, so here's my solution for others who get stuck in the same place:

onStartCommand....

config = SocialAuthConfig.getDefault();

try {
    config.load("assets/oauth_consumer.properties");
} catch(Exception e) {
    Log.e(DEBUG_TAG, "SocialAuthConfig.load 1 Exception", e);
}


manager = new SocialAuthManager();

try {
    manager.setSocialAuthConfig(config);
} catch(Exception e) {
    Log.e(DEBUG_TAG, "SocialAuthManager.setSocialAuthConfig 1 Exception", e);
}

then down in the AsyncTask....

                provider = manager.connect(currentAccessGrant);

                provider.registerPlugins();

                try {
                    contacts = provider.getContactList();
                } catch (Exception e) {
                    Log.e(DEBUG_TAG, "Possible expired token?/n", e);
                }
