アプリに Facebook を統合し、いくつかのコンテンツを共有しようとしています。FaceBookMain () を呼び出すと、次のようなエラーが表示されます。このエラーは、ブラウザ (Webview) で Facebook にログインした後に発生する場合があります。それ以外の場合は、共有ボタンをクリックした直後に発生します。
ここで最も重要なことは、シミュレーターでこの問題に直面していないことです。Facebook との共有は、シミュレーターでは正しく機能していますが、デバイスでは機能していません。
それにいくつかのクラスファイルを追加しています：
FacebookMain.java クラスは次のとおりです。
