Enable automatic download of missing Android SDK packages in Gradle

[simonppg]

Based on this stackoverflow question setting android.builder.sdkDownload=true and android.sdk.channel=2 on gradle.properties file, will auto download the Android SDK. I got a waning about android.sdk.channel=2 being a experimental feature. so I set classpath "com.android.tools.build:gradle-experimental:0.7.0-alpha4" on gradle.build file. This remove the warning but another an error shows that the ANDROID_SDK_ROOT variable was not set. Setting sdk.dir=/path/to/Android/Sdk on local.properties was the solution. But another error show up saying the SDK will not start downloading because the license was not accepted but so far I can't find a way to accept it.
