My app import admob:

com.google.android.gms:play-services-ads:8.4.0

But it make my app very big, I found there are "drawable-xxxhdpi", "drawable-tvdpi" from this library with very large images, I want to delete(exclude) those from this library.

I used "**resConfigs**" in gradle to just include the density folders I needed before, 

but not sure since when the "resConfigs" for density is **not supported**, 

<https://code.google.com/p/android/issues/detail?id=179136>

The apk split in density seems not fit my requirements.

**what should I do now?**
