I have this strange error when installing apk on device, from Eclipse. The console gives error message: Failed to install, but in fact the file is installed.
Also, the application doesn't start after the installation, I have to do it manually.
I have done the this same procedure over and over again, without problems, but now the error occurs.
Thanks!
I've found that sometimes a device gets stuck in a strange state, and no matter what you do will give odd errors on install. Turning the device itself on and off again usually cures the problem.
