A generic OAuth Provider for Android
This project uses the excellent Signpost library for OAuth 1.0a authentication.
##Notes The project is in its very early stages and requires a lot of work.
This project aims to provide a generic, lightweight OAuth solution which you can use in your projects to authenticate yourself with multiple services using OAuth authentication. The library supports both OAuth 1.0a and OAuth 2.0.
The library has default settings for common services(Facebook and Twitter as of now, more coming later).
It is assumed that the user is already familiar with the OAuth flow.
You can either add this as a library project or copy the source code directly into your own project. Remember to copy the Signpost libs from the /libs directory and add them to the build path in case of the latter.
OAuthFactory facebookFactory = new OAuthFactory(MainActivity.this, "MY_CLIENT_ID", null, Provider.FACEBOOK, null, "MY_CALLBACK_URL");
facebookFactory.getOAuthConfig().customOAuthParams = new String[] { "scope=read_stream,publish_actions" };
facebookFactory.authorize(REQUEST_CODE);This will open up a WebActivity in which you will be redirected to the Facebook OAuth Dialog and you can sign in. In order to retrieve the access token, override onActivityResult() as follows
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode) {
case REQUEST_CODE: {
if(resultCode == FactoryConstants.SUCCESS) {
try {
AccessToken token = facebookFactory.authorizeCallback(data.getExtras());
Log.d("Tag", "Token:" + token.getToken() /*+ " Secret:" + token.getTokenSecret()*/);
} catch (OAuthMessageSignerException e) {
e.printStackTrace();
} catch (OAuthNotAuthorizedException e) {
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
e.printStackTrace();
} catch (OAuthCommunicationException e) {
e.printStackTrace();
}
}
else if(resultCode == FactoryConstants.FAILURE) {
Log.d("Tag", "Failure");
}
break;
}
}
super.onActivityResult(requestCode, resultCode, data);
} OAuthFactory twitterFactory = new OAuthFactory(MainActivity.this, "MY_CONSUMER_KEY", "MY_CONSUMER_SECRET", Provider.TWITTER, null, "MY_CALLBACK_URL");
twitterFactory.authorize(REQUEST_CODE);Retrieving the access token is done in exactly the same way as for Facebook. After connecting to Twiiter, you can use the same twitterFactory instance to sign any HttpRequests as follows:
HttpGet get = new HttpGet("SOME_URL_THAT_NEEDS_SIGNING");
twitterFactory.signHttpRequest(get);Coming Soon!
