    The system cannot find the path specified.
    This sort of says it all. I presume you're using Qt Creator. Make sure you have the Android kit properly configured by following the steps here exactly. Do as they say at the bottom of the "Getting Started" page - build one of the Qt Examples using the Android kit. It is easier to do that and verify a correct install than it is to start with a brand new project and figure out what's wrong.

    I found that I had to disable the "make install" step in the Android build. It doesn't work for whatever reason, but the deployment step that follows works just fine.

    My guess in your case is that Windows can't find one of the executables it needs for the toolchain - either qmake, mingw32-make, or g++. Check the kit configuration.
