In the Facebook Developers site, add the Android Key Hash to your App. See https://developers.facebook.com/docs/android/getting-started.
If needed, set the following properties in gradle.properties depending on your app's requirements. See https://github.com/greenhalolabs/facebooklogin/blob/master/gradle.properties.

In your app's AndroidManifest.xml file, add a reference to FacebookLoginActivity. See https://github.com/greenhalolabs/facebooklogin/blob/master/sample/src/main/AndroidManifest.xml.
<activity android:name="com.greenhalolabs.facebooklogin.FacebookLoginActivity" />
To launch Facebook Login, here's a sample:
String applicationId = getResources().getString(R.string.facebook_app_id);
ArrayList<String> permissions = new ArrayList<String>();
permissions.add("public_profile");
FacebookLoginActivity.launch(this, applicationId, permissions);
To get Access Token, use onActivityResult,
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == FacebookLoginActivity.FACEBOOK_LOGIN_REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK) {
String accessToken = data.getStringExtra(FacebookLoginActivity.EXTRA_FACEBOOK_ACCESS_TOKEN);
Toast.makeText(this, "Access Token: " + accessToken, Toast.LENGTH_LONG).show();
}
else {
String errorMessage = data.getStringExtra(FacebookLoginActivity.EXTRA_ERROR_MESSAGE);
Toast.makeText(this, "Error: " + errorMessage, Toast.LENGTH_LONG).show();
}
}
}
