如何修复资源未找到异常？
How to fix Resource not found exception?
我在 Android Studio (3.1.2) 中工作，我有一个应用程序最初是在 运行 InstantApp 管理器下创建的。 我相信这就是将其分为 3 个主要目录的原因：app、base、feature。
注意：突出显示相关文件...
无论如何，问题是找不到资源。
我正在尝试自定义 SeekBar 并使用渐变形状作为背景。在 feature.res.values.style.xml:
<?xml version="1.0" encoding="utf-8"?>
<style name="alphaSliderStyle" parent="@android:style/Widget.SeekBar">
<item name="android:indeterminateOnly">false</item>
<item name="android:progressDrawable">@drawable/alpha_progress</item>
</style>
我的理解是 alpha_progress.xml 文件应该在 feature.res.drawable 下。但是，当 运行 应用程序实例化显示自定义 SeekBar 的视图时，我得到以下内容（摘录）：

相关位似乎是：
Caused by: android.content.res.Resources$NotFoundException: Drawable com.razorware.cloudcard.app:drawable/alpha_progress with resource ID #0x7f08005b
Caused by: android.content.res.Resources$NotFoundException: File res/drawable/alpha_progress.xml from drawable resource ID #0x7f08005b
...特别是它正在寻找 app.res.drawable 位置（如果我理解正确的话）。
关于它的价值，这里有另外两个相关的内容drawables：
// alpha_progress.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">

resource can not be found.
您应该在 item 部分中设置 android:drawable。
<item android:id="@android:id/background"
android:drawable="@drawable/alpha_color_sample">
</item>
我假设 <bitmap android:src 造成问题，因为 alpha_color_sample 不是有效的 位图.
修改后Clean-Rebuild-Run.
