tl;dr: I'm running into an issue with the Crosswalk webview project that, I think, means we have to abandon our custom ant-build and ant-gen directories.
Some time ago, we put in some override rules into cordova-android's Ant build config. This was done because the defaults, "bin" and "gen", are also used by Eclipse, and if you ran Eclipse and the command line tools on the same project, they would step all over each others' build artifacts. The only solution at the time was to do a full clean before each build, making incremental (fast) builds impossible. There's a problem, though -- it turns out that when the Android AAPT packager tool collects all of the resources from the /res/ directories, it is *hard coded* to put its artifacts in /bin/. (Here's a fun line of code: https://android.googlesource.com/platform/tools/base/+/master/legacy/ant-tasks/src/main/java/com/android/ant/ComputeDependencyTask.java#203 ) The result of this is that the project compiles, but without all of the resources needed for a XWalk WebView. The app runs, but fails at run-time to construct the view, and falls back to the system WebView. This would also be a problem for any other library projects that use /res/ folders. Turning off our custom build rules fixes this, but now we're back to the old situation. I don't see another way to handle this, though. I think I'm going to have to revert the commit that changed the build directories, on the 4.0.x branch at least. I'll add an issue for supporting Gradle as well; it shouldn't have this particular issue; and then at some point in the future we can go back to supporting fast builds again. Ian
