Android 21 API中的底杆充气异常

我在我的android项目中使用底部栏。我总是习惯于API 24。但是当我尝试使用API21时。我的项目有一个例外。我在网上搜索。但我什么也没找到。当我转到底部栏中的活动时，İt会给我一个例外。顺便说一句我搜索了我的项目，没有编码错误。当我从布局中删除底部栏时。例外情况已经过去了。我怎样才能修好它

我的标签：

<?xml version="1.0" encoding="utf-8"?>
<tabs>
    <tab
        id="@+id/ana"
        icon="@drawable/news"
        title="Vitrin" />
    <tab
        id="@+id/find"
        icon="@drawable/foot"
        title="Ziyaretçi" />
    <tab
        id="@+id/add"
        icon="@drawable/ic_photo_camera_black_24dp"
        title="" />
    <tab
        id="@+id/chat"
        icon="@drawable/chat"
        title="Mesajlar" />
    <tab
        id="@+id/user"
        icon="@drawable/ic_person_black_24dp"
        title="Profil" />
</tabs>

我毕业时的图书馆：

编译'com.roughike:底部栏：2.3.1'

底栏布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".bottom_bar">


    <FrameLayout
        android:id="@+id/content_id"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="horizontal"
            android:gravity="right">

        </RelativeLayout>
    </FrameLayout>


    <com.roughike.bottombar.BottomBar
        android:id="@+id/bottomBar"
        android:layout_width="match_parent"
        android:layout_height="45dp"
        android:layout_alignParentBottom="true"
        app:bb_tabXmlResource="@xml/tab" >

    </com.roughike.bottombar.BottomBar>



</LinearLayout>

如果您浏览stacktrace，您可以看到：

Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f080078       
at android.content.res.Resources.getValue(Resources.java:1233)
at android.support.v7.widget.AppCompatDrawableManager.loadDrawableFromDelegates(AppCompatDrawableManager.java:328)

所以图标有问题

您是否向资源中添加了tab.xml。。。？如果有，它会抱怨缺少一个可绘制/图标。是的。是的。我正在编辑，杜克。非常感谢。图标有问题。请回答我的问题。你的回答是对的。顺便说一句如何理解图标存在问题？
