Project 'XYZ' is missing required source folder 'gen'

December 17, 2012 - 10:29am #1

Hello,

 

I have tried building both the ImageTargets and Dominoes sample apps according to the instructions given, but I come across two errors.  The first is the title of this post.  The second is: "unable to resolve target 'android-16'".

 

I have tried finding anything about the 'gen' folder, and I don't know what to do.  I really can't find a folder marked 'gen' and every response to this error I've seen on the Internet already has said folder.  They just delete it and it repairs itself.

 

I haven't seen anything helpful on the forums about my second error either.

 

Any help would be appreciated.

Project 'XYZ' is missing required source folder 'gen'

Hi!

I had the same problem a month long but with this:

 

"alternatively, you can open and edit the project.properties file and set the "target" to a lower API value (for instance to "android-8" or "android-10", etc. , depending on which API level you have installed)"

 

It works for me.

 

Thanks a lot.

Hi ramortis,

Eclipse shows that error message when it fails to build the project (probably due to some other errors); check the list of errors in your Problems panels at the bottom and try to see what needs to be fixed; for example, one possibility is that you may need to upgrade your android SDK version.

Hi, the error "unable to

Hi, the error "unable to resolve target 'android-16'" is usually due to the fact that you have not installed the Android API level 16;

you can fix that by using the SDK Manager in Eclipse and install that API level (which corresponds to Android 4.1);

alternatively, you can open and edit the project.properties file and set the "target" to a lower API value (for instance to "android-8" or "android-10", etc. , depending on which API level you have installed) 

If you fix this, then the other issue you mention might get fixed automatically by Eclipse;

if not, then you can go to project -> properties -> Java Build Path -> go tp the  "Source" tab,  click on the "/gen" folder and Remove it, so to force Eclipse to regenerate it.

IHTH.
