    hi
    I have a program working in the Android Emulator. Every now and again I have been creating a signed .apk and exporting it to my HTC Desire to test. It has all been fine.

    On my latest exported .apk I get the error message 'App not installed' when I try to install the .apk. It runs fine on the emulators.

    As I have mainly been testing on the emulators and only every now and again exporting to a real phone I am not sure when this happened. What is the likely cause of it not installing on a physical phone but running fine in the emulators?

    I have tried rebooting the phone & removing the existing .apk, does not fix the fault.
