        android:textSize="28sp"
        android:textStyle="bold"/>

</LinearLayout>

问题原因与解决方案 #

• 问题根源：第二个TextView中设置了空字符串的android:fontFamily=""，系统尝试加载该字体时触发NullPointerException，进而引发InvocationTargetException。
• 解决步骤：
  1. 直接移除布局中第二个TextView的android:fontFamily=""属性；
  2. 若需要指定字体，替换为有效的字体名称（如sans-serif、自定义字体资源引用等）。

修改后的第二个TextView代码示例：

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="28dp"
    android:text="@string/verify_your_number"
    android:textColor="@color/teal_200"
    android:textSize="28sp"
    android:textStyle="bold"/>
