我正在开发一款具有base模块和2个功能模块的即时应用：feature1和feature2。当我尝试启动feature2活动时，我遇到了奇怪的崩溃：

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个资源中。如果我们将其删除，或将其更改为base资源中的某些可绘制内容，则一切正常。
另一个奇怪的是这一行：
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，根本不应该被引用。但是，如果我们转到feature2\R.java文件，并查找progress.xml drawable，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有一位数不同：0x80030011和{ {1}}。所以我做了一个假设，0x82030011由于未知原因在feature2资源中查找progress drawable。我试图删除feature1依赖关系并且崩溃消失了，这证实了我的假设。
我还应该注意，只有Instant App会出现此问题。已安装的应用程序运行正常。
我的问题是feature1如何搜索feature2 apk中的资源？您是否有任何想法导致此行为或可能提示如何调试此问题？
答案 0 :(得分：1)
参考 Google issue tracker，已将Android SDK内置工具修复为27.0.2
请将您的 Android SDK内置工具更新为27.0.2
并确保您使用 Android Studio 3.0.1或更高版本。
