Support applicationId prefixed with "fb"

[nodrock]

It would be great to have opportunity to force applicationId to be string. Otherwise if you specify applicationId directly through Android manifest (not through constant in strings.xml file) it will overflow to 32-bit int instead of string. I suggest to support also applicationIds with prefix "fb" which will ensure that it will be parsed to string correctly. It will be also similar to CFBundleURLSchemes in iOS version of SDK which is also prefixed by "fb".

Hi nodrock thanks for your pull request and for bringing to light the issue with the integer overflow for app ids. Currently our recommended method, and Google's, for dealing with longs in the config is to place the long in a string resource file like we do for our samples.
https://github.com/facebook/facebook-android-sdk/blob/master/samples/Scrumptious/AndroidManifest.xml#L60

But I like your idea of the fb though to match our iOS SDK.

Do you also want to remove the attempt to parse the ID as an Integer since its unlikely that AppIds will fit in a 32 bit int?

Yes I read the recommended method, but I cannot apply it in my project, because I don't have access to resource files only to part of manifest file. I work on open source project to provide Facebook SDK for Adobe Air applications as native extension and I would like to provide easy way to set ApplicationId in manifest file not only through code.

Anyway, I agree there is no sense in leaving there code for 32bit ints so I will change the request to:

...
if (applicationId == null) {
  applicationId = ai.metaData.getString(APPLICATION_ID_PROPERTY);
  if(applicationId != null && applicationId.startsWith("fb")){
    applicationId = applicationId.substring(2);
  }
}
