This seems to pop up randomly. I build with grunt/bower and this has happened a couple times where I go to make a change, then re-run the emulator, I get this error. I have tried restarting the XDK, also tried removing the project from XDK and reloading it, but then I get a "Intel XDK failed to locate the scratch directory..." error. I have found if I completely remove the project from the directory and put it back, it seems to work again. Haven't tried a system restart yet, but I'll see if that works.
The bug with emulator not finding app - 404: Intel XDK can't find your app - has been identified and being fixed and will be available soon, meanwhile the workaround is you can remove the project completely and move it back or you can switch to another project from the project list and come back to your project.
I am having the same issue. It worked fine on the previous version of Intel XDK, but the new 1878 version I get the "404 Intel could not find your app" error. It also ask me if I have an index.html in my source directory which I have. I can test the app on my phone using the Debug option.
Still having an issue. It seems to definitely happen every time I search throughout the file system. I even tried loading the project through "Start a new project" and then "Import Your HTML5 Code Base" and it still gave me issues. Hopefully there is a fix soon.

I am having the same issue, from time to time. It seems to occurs when you save a file and quickly click on Emulate. When it occurs, I return to developer, wait a few seconds and try again. Normally it solve the problem.
404 - can't find index.html and "The Intel XDK can't stop the app because the connection to the device is flaky. Please swipe out the app manually, and click 'Continue'. To prevent this issue from happening again, please re-connect your test device."
Are you seeing this message in the emulator or on the device?? with a built app or with debug tab? Please provide details of your issue. Your OS, which platform are you trying on? Provide some screenshots of the error.
The recent emulator error is due to recent change in Cordova container. Please see this sticky post for details and workaround : https://software.intel.com/en-us/forums/intel-xdk/topic/623584
