Problems running application in the emulator and on the mobile device.

Hello! I'm having trouble running the emulator and also on my mobile device. What is below is what I get after being in construction mode, I have no idea who might be. I am new to this. Thank you.

At line 284 in build.xml (assuming that you are running the same version of the SDK tools that I am), we have the following ant definition that locates dex:

<dex executable="${dx}"
        output="${intermediate.dex.file}"
        dexedlibs="${out.dexed.absolute.dir}"
        nolocals="@{nolocals}"
        forceJumbo="${dex.force.jumbo}"
        disableDexMerger="${dex.disable.merger}"
        verbose="${verbose}">
    <path path="${out.dex.input.absolute.dir}"/>
    <path refid="out.dex.jar.input.ref" />
    <external-libs />
</dex>

dex should be located in .../sdk/platform-tools/lib/, named dx.jar.

I'm surprised that you got such an ambiguous error message. The most likely culprit is that your Android SDK and / or your Android ADT isn't installed correctly. More details could lead to a better solution. This problem has been experienced on these forums before.
