android.view.InflateException:バイナリXMLファイルの行#2:クラス<unknown>の拡張エラー

シンプルなアプリを開発しています。ホーム画面が完成しました。方向が2回を超えて変化する場合、エラーがスローされ、アプリケーションは強制的に閉じられます。

私の活動コード:

public class PasswordActivity extends Activity implements OnClickListener {
Button login;  
Button forgot;
Button register;  

private static final String PREFERENCES = "prefs";
private static final String PREFERENCES_NAME = "pref_name"; 
SharedPreferences settings;
private Cursor c;

@Override 
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main); 
    login=(Button)findViewById(R.id.login_login);
    login.setOnClickListener(this);
    register=(Button)findViewById(R.id.login_register);
    register.setOnClickListener(this);

}
public void onClick(View v) {
}

}

画像のサイズは約5kbです。

実行時に、Android必要に応じて(画面のサイズと解像度に基づいて)画像のサイズを変更します。内部的にサイズ変更を行うためにビットマップを使用します。このような問題を修正する簡単な方法の1つは、すべての描画可能ファイルをdrawable-ldpi、mdpi、hdpiフォルダーにコピーすることです。この方法Androidはこれらのフォルダーからファイルを取得するサイズを変更しません。

そのランダムな種類の例外、修正する本当の痛み。
