Question

我在textview的左侧drawable中使用了一个矢量文件：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
    android:viewportHeight="24.0">
    <path
         android:fillColor="#FFFFFFFF"
         android:pathData="M7,10l5,5 5,-5z"/>
</vector>

这导致Android版本强制关闭低于5.0（此FC）。

 Caused by: android.content.res.Resources$NotFoundException: File res/drawable-nodpi-v4/ic_arrow_drop_down.xml from drawable resource ID #0x7f0200ac
 Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #1: invalid drawable tag vector

Android版5.0正常运行。

致命的例外：主要

根据这个blog post，解决这个bug的方法是创建一个引用向量的可绘制资源文件：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_chat_black_24dp" />
</selector>

，它解决了我的问题。另见：Using android vector Drawables on pre Lollipop crash。

在TextView中使用矢量图像左侧可绘制导致力关闭？
