Android Eclipse errors on launch

Question

I am developing an android app using Eclipse. All has been going well until I tried to deploy it to my device last night. When I clicked Run, I was presented with the following:

[2012-04-26 09:00:52 - Unicyclist] Android Launch!
[2012-04-26 09:00:52 - Unicyclist] adb is running normally.
[2012-04-26 09:00:52 - Unicyclist] Performing com.unicycle.UnicyclistActivity activity launch
[2012-04-26 09:00:52 - Unicyclist] Automatic Target Mode: Unable to detect device compatibility. Please select a target device.
[2012-04-26 09:01:05 - Unicyclist] Uploading Unicyclist.apk onto device 'SH0AZR805746'
[2012-04-26 09:01:05 - Unicyclist] Failed to install Unicyclist.apk on device 'SH0AZR805746': No such file or directory
[2012-04-26 09:01:05 - Unicyclist] com.android.ddmlib.SyncException: No such file or directory
[2012-04-26 09:01:05 - Unicyclist] Launch canceled!

It sounds like the directory it is attempting to install to on the phone is missing. Or perhaps it's a directory on my computer? I can't find anything on this by searching, and I'm not sure how to debug this.

• This is a phone, not a virtual device.

• The phone is running cyanogenmod, not stock.

• A bunch of apps updated last night (related?) I re-imaged the phone from a backup, and the app deployed correctly. Then I updated the apps that had changed since last backup, and left it overnight. This morning, it won't deploy again (same problem)

• The app launches fine on another tablet, and fine in a virtual device

• My dev environment is in a dropbox folder, if that makes any difference. I switch between developing on a windows and 2 linux computers.

• Same problem occurs on both linux computers with this phone (haven't tried windows yet)

Answer 1

The problem is that Eclipse is not capable of finding your apk file. Just try build clean. Here is another similar question.
