Beispielprojekt/Tutorial zur Demonstration verschiedener Merkmale von SocialLibs in Android

Question

Über SocialLib:

http://www.androidlibs.com/sociallib.html

http://code.google.com/p/sociallib/wiki/advancedguide

http://code.google.com/p/sociallib/wiki/sociallibguide

SocialLib zielt darauf ab, die Entwicklung sozialer Apps zu erleichtern. Derzeit bietet Social LIB Zugang zu den folgenden sozialen Netzwerken:

• Facebook
• Twitter
• Google
• Summen
• LinkedIn

Jetzt mein Szenario:

Ich habe Apps in Twitter, Facebook erstellt und API- und Geheimtasten generiert.

Ich habe versucht, dem Leitfaden auf der Wiki -Seite von SocialLibs zu folgen.

Aber leider stecke ich fest. Ich brauche jemanden, der auf eine Arbeitsquelle der Verbindung hinweist und auf Facebook, Twitter ... usw. veröffentlicht wird

Hier ist der Code, den ich ausprobiert habe. Kann mich jemand korrigieren, wenn es einige Fehler gibt.
Java -Code:

Answer 1

Es scheint, dass eine OAuth -Bibliothek fehlt. Ist es möglich, dass Sie einbeziehen müssen? OAuth-Signpost?
