tensorflow: Android Demo - Bug - Exception in TF Detect activity

System information

• Have I written custom code (as opposed to using a stock example script provided in TensorFlow): At build.gradle (Module: android) def nativeBuildSystem = ‘none’ At CameraActivity.java: useCamera2API = true; Suggested by @andrewharp at #12431
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows version: 10 Pro Android version: 6.0.1 Demo version: commit 18e4590
• TensorFlow installed from (source or binary): x
• TensorFlow version (use command below): x
• Python version: x
• Bazel version (if compiling from source): x
• CUDA/cuDNN version: x
• GPU model and memory: x
• Exact command to reproduce: x

Describe the problem

Running the activity TF Detect after installing the project with Android Studio results in an IllegalArgumentException being thrown.

The problem has been noticed before with other configurations at issue #12431 and pull request #10771 and tested recently by @ArtsiomCh using CMake and Ubuntu.
