Question

我在Linux上使用android studio 3.1.2，使用以下设置：

compileSdkVersion 27
buildToolsVersion '27.0.3'
minSdkVersion 16
targetSdkVersion 19
Gradle version: 4.4
Android plugin version: 3.1.2

我的项目使用以下依赖项：

implementation 'com.google.android.exoplayer:exoplayer-core:2.8.0'
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.google.firebase:firebase-core:15.0.2'
implementation 'com.google.firebase:firebase-crash:15.0.2'
implementation 'com.google.firebase:firebase-messaging:15.0.2'
implementation 'com.google.android.gms:play-services-plus:15.0.1'
implementation 'com.android.support:palette-v7:27.1.1'
implementation 'com.google.code.gson:gson:2.8.0'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'

在棒棒糖前设备上 - SDK＆lt; 21，我得到以下例外：

我已经遵循了其他建议并取而代之：

android:src至app:srcCompat，
在 build.gradle 和

vectorDrawables.useSupportLibrary = true

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true) 在公共类中，HomeScreen扩展了AppCompatActivity {

但这并没有解决我的问题。

从第68行开始，查看来自homescreen_layout.xml的摘录

 <View
    android:layout_width="14dp"
    android:layout_height="14dp"
    android:layout_marginBottom="6dp"
    android:layout_marginEnd="5dp"
    android:layout_marginRight="5dp"
    android:background="@drawable/ic_share_black_24dp"
    app:layout_constraintBottom_toBottomOf="@+id/music_image"
    app:layout_constraintRight_toRightOf="@+id/music_image" />

这是ic_share_black_24dp.xml文件的内容：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:width="14dp"

我在这里做错了什么？任何帮助表示赞赏。

谢谢！

Answer 1

从Logcat

中可以看出2个错误

 1. Caused by: android.content.res.Resources$NotFoundException: File res/drawable/ic_share_black_24dp.xml from drawable resource ID #0x7f08009b
 2. Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #1: invalid drawable tag vector

如果升级后也遇到同样的错误，那么

逐一尝试，不管有效。

确保您的命名匹配，因为它无法找到它，我建议您：

一个。 Invalidate Caches/Restart，

湾如果没有，删除 .idea＆amp;来自项目位置的.gradle

℃。如果没有，删除资源，清除项目，重新创建资源
确保您的ic_share_black_24dp未在项目的其他任何位置使用，即左侧抽屉面板（导航菜单）＆amp;右侧面板（导航菜单），如果是，则重命名其中一个资源

此外，请尝试使用此矢量资源

<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="#FF000000"
        android:pathData="M18,16.08c-0.76,0 -1.44,0.3 -1.96,0.77L8.91,12.7c0.05,-0.23 0.09,-0.46 0.09,-0.7s-0.04,-0.47 -0.09,-0.7l7.05,-4.11c0.54,0.5 1.25,0.81 2.04,0.81 1.66,0 3,-1.34 3,-3s-1.34,-3 -3,-3 -3,1.34 -3,3c0,0.24 0.04,0.47 0.09,0.7L8.04,9.81C7.5,9.31 6.79,9 6,9c-1.66,0 -3,1.34 -3,3s1.34,3 3,3c0.79,0 1.5,-0.31 2.04,-0.81l7.12,4.16c-0.05,0.21 -0.08,0.43 -0.08,0.65 0,1.61 1.31,2.92 2.92,2.92 1.61,0 2.92,-1.31 2.92,-2.92s-1.31,-2.92 -2.92,-2.92z"/>
</vector>

修改：在您的View标记中，请更改此内容：

android:background="@drawable/ic_share_black_24dp"

到此：

app:srcCompat="@drawable/ic_share_black_24dp"

使用可绘制矢量SDK＆lt; 21：二进制XML文件行＃68：错误导致类<unknown>无效的可绘制标记向量
