I believe this is JAVA related. I see solutions elsewhere advising going into src> my project > main.java and then checking the code within there. Problem is I don't see any 'main.java' folder in BT source code. I believe the problem started when I saved a couple of images in using a underscore (_) or a space in the file name. Images are in the res>drawable>drawable-hdpi folder. In my 'Problems' screen under 'Path' it refers to '...BT_activity_root_src...' I went from a running app to 413 errors with that mistake. Suggestions &/or fixes? tia, John

Have you removed underscores/spaces from image names? If so, save project and try a Project > Clean

raveyd, That worked - and was SO simple! I also noticed I had used a Capitol letter in another pic - another no-no. I'm back in business. THX!

hehe! not much is simple in eclipse! It's some tough software to get playing nicely. Glad it worked.

You get that error also if your project API isn't set to Google 2.2.

Hi Susan, I've had my share of Google API 2.2 issues - but I don't think that was the case here (but as a 'almost born yesterday rookie' I could be wrong). Thx for the feedback - I'll keep in my list of errors & fixes. John

I know this is an old thread, but I spent several hours trying to figure this one out, so hopefully someone will benefit from this answer. For me (I'm on Windows 7 by the way), I went into the Android SDK manager (If your in Eclipse you go to Windows/Android SDK Manager)and installed the "Android SDK Platform-tools." I'm brand new at this (just started yesterday) so I don't know why this fixed my problem, but it did. Hope this helps. -Ammon

Android SDK platform-tools an absolute necessity, strange it didn't get installed when you installed the sdk? Make sure everything in the sdk manager is up to date, it's a fast moving environment. I'm updating as we speak, it's been going for over an hour, yet it was fully up to date just a few weeks ago.
