[BUG] Improvements for apps/Android/ImageClassification/build_apk.py

Describe the bug

There is an issue with build_apk.py: when only the qnnsdk and model_path are input, the model selection menu should not be printed using printmenu(), because the model will invariably be assigned the value of 'classification.tflite'.

I have modified the decision rule: the model selection menu will only be printed if neither model_name nor model_path has been provided.
It is suggested that line 45 be changed to:
if not args.model_name and not args.model_path:
