        minSdkVersion 15
        targetSdkVersion 23

Seems like Minim is not fully supported on Android. The problem might be you're using JDK 7 and Minim is using JDK 8 (just a guess). Although you can enable JDK 8 on Android , not all Java 8 features are supported yet.

I recommend you using Minim-Android instead and see if it has all the features you need in your project.
