我正在开发一个 Instant App，它有 base 模块和 2 个功能模块:feature1 和 feature2。当我尝试启动 feature2 Activity 时出现奇怪的崩溃:

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" />
Drawable progress.xml 位于 feature2 资源中。如果我们删除它，或将其更改为 base 资源中的某个可绘制对象，一切正常。
另一件奇怪的事情是这一行:
Caused by: android.content.res.Resources$NotFoundException: Drawable com.test.myapp.qa:layout/random_feature1_layout with resource ID #0x82030011
Layout random_feature1_layout 位于 feature1 资源中，根本不应被引用。但是，如果我们转到 feature2\R.java 文件，并查找 progress.xml 可绘制对象，我们会发现:
public static final int progress=0x80030011;
如果你仔细观察，你会注意到 progress 和 random_feature1_layout 的 id 有一个数字的不同: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 可绘制对象。我尝试删除 feature1 依赖项，崩溃消失了，这证实了我的假设。
我还应注意，此问题仅在 Instant 应用中出现。安装的应用程序运行良好。
我的问题是 feature2 怎么可能在 feature1 apk 中搜索资源？您是否知道导致此行为的原因或可能提示如何调试此问题？
最佳答案
引用 Google issue tracker , 它已通过 Android SDK Built-Tools 修复到 27.0.2
请将您的 Android SDK Built-Tools 更新到 27.0.2
并确保您使用的是 Android Studio 3.0.1 或更新版本。
如果任何问题仍然存在，请报告 at Google issue tracker他们将重新打开检查。谢谢!
