我得到这个错误,而我正在构建APK。

试图使缓存无效并重新启动android工作室。重建项目,但没有一个为我工作。
当你试图构建一个使用VectorDrawable作为自适应图标的应用程序时,你可能会遇到这样的错误。和你的XML文件包含"android:fillColor"与<梯度>块:
res - drawable icon_with_gradient xml。
<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:aapt="http://schemas.android.com/aapt"
android:width="96dp"
android:height="96dp"
android:viewportHeight="100"
android:viewportWidth="100">
<path
android:pathData="M1,1 H99 V99 H1Z"
android:strokeColor="?android:attr/colorAccent"
android:strokeWidth="2">
<aapt:attr name="android:fillColor">
<gradient
android:endColor="#156a12"
android:endX="50"
android:endY="99"
android:startColor="#1e9618"
android:startX="50"
android:startY="1"
android:type="linear" />
</aapt:attr>
</path>
</vector>
渐变填充颜色通常用于自适应图标,例如在教程中这里,这里和这里。
即使布局预览工作正常,当你构建应用程序时,你会看到这样的错误:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:mergeDebugResources'.

解决方案是将文件icon_with_gradient.xml移动到drawable-v24/icon_with_gradient.xml或drawable-v26/icon_with_gradient.xml。这是因为梯度填充只在API 24 (Android 7)及以上版本中支持。VectorDrawable:无效的可绘制标签梯度
解决方案:
Caused by 4: com.android.builder.internal.aapt.AaptException: Dependent features configured but no package ID was set.
所有特性模块都必须应用库插件,而不是应用程序插件。
构建。gradle (androidApp: feature_A)
apply plugin: 'com.android.library'
这完全取决于每个组件的堆栈跟踪。原因1 WorkExecutionException可能是其他原因导致的。因此,我建议从最后一个原因到第一个原因读取完整的堆栈跟踪。因此,如果我们解决了最后一个原因,很可能我们就已经固定了从最后一个原因到第一个原因的链条。
我附上我的堆栈跟踪的一个例子,原始或具体的问题是在最后的原因:
