ionic build android failure - Execution failed for task processDebugResources

I am using Mac Yosemite. Getting the following failure on running a build for android platform :

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':processDebugResources'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:

The build runs perfectly fine for IOS. I have installed android SDK and configured ANDROID_HOME and ANDROID_SDK_ROOT system variables.

Also tried removing the platform and adding it again, to have a clean platform folder using :

ionic platform remove android
ionic platform add android

But no good.

Android SDK build tool versions that I have installed - 19.1,20,21.1.2 and 22.0.1

AndroidManifest.xml preference :

 <uses-sdk android:minSdkVersion="16" android:targetSdkVersion="22" />
