Hi, I’ve problems building the android app from source.  
I’m getting an exception: “com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536”.

Has anyone manage to build the master version of habdroid without problems?

I have a fix that will allow me to build, but I’m not sure if that is a correct fix: [Step android gradle plugin version to 1.5.0 · hazzeh/openhab.android@9913fbe · GitHub](http://github.com/hazzeh/openhab.android/commit/9913fbe5d7f774f7b197f5f45a1b23349a38d4d4)  
This commit also steps the android gradle plugin version to one that is accepted by newer android studio versions.  
If it is a valid correction I can create a pull request.

BR,  
Hans

I had the same error, adding  
`multiDexEnabled true` resolve compilation problem.

We also should change extends of `org.openhab.habdroid.core.HABDroid` to `android.support.multidex.MultiDexApplication` to support older version of Android.

That looks good, it would be nice if it can be merged into master. Then I can rebase my pull requests for fixing issue #153.
