Why is BUILD FAILED?

Question

I am trying to run simplest Qt application on android device. There are AVD and real phone with android. For both of them I get error:

BUILD FAILED

I had the same problem. Adding these lines to build.xml file solved it:

<property name="aidl" location="${sdk.dir}/build-tools/22.0.1/aidl${exe}" />
<property name="aapt" location="${sdk.dir}/build-tools/22.0.1/aapt${exe}" />
<property name="dx" location="${sdk.dir}/build-tools/22.0.1/dx${exe}" />
<property name="zipalign" location="${sdk.dir}/build-tools/22.0.1/zipalign${exe}" />

Answer 2

It seems some Android SDK version (22, for instance) are missing several tools in the ant build.xml. So lines described above in mastertoster's answer should be added to <sdk root>/tools/ant/build.xml file.
