IBM Watson speech to text for Android: NoClassDefFoundError

Question

Has anyone seen this error? Know how to fix it? Please help me.

I am using the IBM Watson speech to text library, and trying to make it record the voice when button pressed, and stop record when button released.

I have read the code sample given, but I get this error:

java.lang.NoClassDefFoundError: com.ibm.watson.developer_cloud.android.library.audio.opus.JNAOpus
