Tensorflow Object Detection Api Index Out Of Bounds

Upon running the Android TF Detect Demo and using my retrained 3 class ssd_mobilenet_v1_coco model my TF detect Demo crashes giving an IndexOutOfBoundException which is 12-26 17:5

Solution 1:

Solved by Adding a "???" string inside my Label file, it seems that the App follows the pbtxt format of having the first ID which is 1.
