jtwitter-yamba.jarを含むプロジェクトが失敗しました

Question

"Androidの学習"ブックからプロジェクトをビルドしています。 thirdparty jtwitter-yamba.jarファイルを含めると、ビルド時にプロジェクトが失敗します。

そして私はそれを削除して実際にその罪人を検証しようとしました。

回避策はありますか？私はtheresがすでにいくつかのtwitter APIがどこかに隠れていると思う。

Answer 1

jarファイルを自分のプロジェクトルートに投げ込み、プロジェクトプロパティで手動でインポートしました。ファイルを右クリックして、パスにインクルードを選択すると間違ってしまうでしょう。
