Answer 1

ClassifierActivity.java belongs to demo app of tensorflow for Android.

Tensorflow demo examples support only API level 21 or greater. It will not work with JellyBean.

Check below official information:

The Android SDK and build tools can be downloaded separately or used as part of Android Studio. To build the TensorFlow Lite Android demo, build tools require API >= 23 (but it will run on devices with API >= 21).
