This issue is caused by the names of a few folders in your project structure. The Android Asset Packaging Tool (aapt) omits the folders starting with "_" and their content accordingly. There is actually an issue
logged in the google issues board discussing this behavior.
The live sync implementation, on the other hand, does not omit these folders and allows you to download them from the cloud to your device. However, in order to have such folders and their contents properly installed on an Android device, I would recommend reconsidering their names.
