When I decode and encode using JSONIC on Android app, I get an Exception error.

I produce Android apps on Android Studio.
When you use JSONIC to do the following, JSON.encode(hm); displays an Exception error and a message indicating that printStackTrace cannot find the library of jsonic.

If there are no Exception errors and you know how to encode and decode using JSONIC, could you please let me know?

try{
    HashMap<String,Object>hm=new HashMap<>();

    hm.put("001", "Strawberry");
    hm.put("002", "Nikan");
    hm.put("003", "Tangerine");

    String json = JSON.encode(hm);
}catch(Exceptione){
    e.printStackTrace();
    return;
}

e.printStackTrace(); Output on the

W/dalvikvm:Exception Ljava/lang/NoClassDefFoundError;thrown while
