问题描述
我正在开发一个Instant App，它具有base模块和2个功能模块:feature1和feature2.尝试启动feature2活动时，我遇到了奇怪的崩溃:
I'm developing an Instant App, that has base module and 2 feature modules: feature1 and feature2. I'm getting strange crash when I'm trying to launch feature2 activity:

如果我们查看Feature2Activity布局文件，则在第76行中将看到:
If we look at Feature2Activity layout file, line 76 we'll see:
<ProgressBar
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="right"
android:indeterminateDrawable="@drawable/progress" />
Drawable progress.xml位于feature2资源中.如果我们将其删除，或将其更改为base资源中的某些可绘制对象，则一切正常.
Drawable progress.xml is located in feature2 resources. If we remove it, or change it to some drawable from base resources, everything works fine.
这行是另一个奇怪的事情:
Another strange thing is this line:
Caused by: android.content.res.Resources$NotFoundException: Drawable com.test.myapp.qa:layout/random_feature1_layout with resource ID #0x82030011
布局random_feature1_layout位于feature1资源处，完全不应被引用.但是，如果我们转到feature2\R.java文件，并查找progress.xml drawable，则会发现:
Layout random_feature1_layout is located at feature1 resources, and shouldn't be referenced at all. But if we go to feature2\R.java file, and look for progress.xml drawable we'll find:
public static final int progress=0x80030011;
如果仔细看，您会发现progress和random_feature1_layout的ID相差一个数字:0x80030011和0x82030011.因此，我做出了一个假设，即feature2由于未知原因而在feature1资源中寻找progress可绘制对象.我试图删除feature1依赖关系，然后崩溃消失了，这证实了我的假设.
And if you look closer you'll notice that progress's and random_feature1_layout's ids are differ by one digit: 0x80030011 and 0x82030011. So I made an assumption, that feature2 for unknown reasons looks for progress drawable in feature1 resources. I tried to remove feature1 dependency and crash disappeared, that confirms my assumption.
我还应该注意，仅Instant应用程序会出现此问题.已安装的应用程序运行正常.
I should also note that this issue is observed only for Instant app. Installed app works fine.
我的问题是feature2如何在feature1 apk中搜索资源?您是否知道导致此行为的原因，或者暗示如何调试此问题?
My question is how is it possible that feature2 searches for resources in feature1 apk? Do you have any ideas what caused this behaviour or maybe hints how to debug this issue?
