   Yes. Your way is good and don't change anything. Do you mean this ? 
   ```python
   from tvm.contrib import cc, ndk
   
   build_func = cc.cross_compiler(ndk.create_shared, options)
   
   tuning_option = {
       // ...
       'measure_option': autotvm.measure_option(
           builder=autotvm.LocalBuilder(
               build_func=build_func if use_android else 'default'),
          ...
       ),
   }
   ```
   No options needed in the builder.
