Android应用在旧版手机上崩溃

Question

我最近在Play商店发布了我的第一款名为“Freaky Fingers”的安卓游戏。实际上，我使用名为“home_button”的文件中的自定义按钮形状为我的按钮提供外边框。

<Button
        android:id="@+id/button_newgame"
        android:layout_width="200dp"
        android:layout_height="70dp"
        android:layout_below="@id/image_home"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="5dp"
        android:background="@drawable/home_button"
        android:text="New Game"
        android:textAppearance="@style/TextAppearance.AppCompat.Large"
        android:textColor="#FFFFFF"
        android:textStyle="bold"

        />

此应用程序适用于Android 4+的新手机，但它在Gingerbread 2.3上崩溃。 崩溃的LogCat给出： -
