# This script generates test code coverage for Android.
# The prerequistes:
#     1. The Onnxruntime build with coverage option to compile/link the source files using --coverage optoin
#     2. The tests are run on the target emulator and *.gcda files are available on the emulator
#     3. The emulator which ran tests must be running. Otherwise this script will fail
