【问题描述】：
我正在开发一个即时应用程序，它具有 base 模块和 2 个功能模块：feature1 和 feature2。当我尝试启动 feature2 活动时，我遇到了奇怪的崩溃：
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.myapp.qa/com.test.myapp.feature2.ui.activity.Feature2Activity}: android.view.InflateException: Binary XML file line #76: Binary XML file line #76: Error inflating class android.widget.ProgressBar

如果我们查看 Feature2Activity 布局文件，第 76 行，我们会看到：
<ProgressBar
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="right"
android:indeterminateDrawable="@drawable/progress" />
可绘制的progress.xml 位于feature2 资源中。如果我们将其删除，或者将其更改为 base 资源中的某个可绘制对象，则一切正常。
另外一个奇怪的地方是这一行：
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 资源中，根本不应该被引用。但是如果我们去feature2\R.java文件，寻找progress.xmldrawable，我们会发现：
public static final int progress=0x80030011;
如果您仔细观察，您会发现progress 和random_feature1_layout 的ID 相差一位：0x80030011 和0x82030011。所以我做了一个假设，feature2 出于未知原因在feature1 资源中寻找progress drawable。我试图删除 feature1 依赖并且崩溃消失了，这证实了我的假设。
我还应注意，此问题仅适用于免安装应用。已安装的应用运行良好。
我的问题是feature2 怎么可能在feature1 apk 中搜索资源？你有什么想法是什么导致了这种行为，或者提示如何调试这个问题？
【问题讨论】：
-
同一资源或同名资源是否也可用于feature1拆分？
-
@MaruAhues 不，它只是一些具有相似 id 的随机资源，它甚至不是可绘制的。
-
我遇到了一个非常相似的问题。我在这里提交了一个错误报告：issuetracker.google.com/issues/62899015
-
在这里发现了另一个跟踪器（可能是同一个问题）：issuetracker.google.com/issues/62852384
-
@gbaccetta 不，我推迟了开发，直到发布更稳定的版本。
