To use: 19# 20# 1. sudo apt-get install lcov 21# 2. Build application/library with coverage information. 22# 3. Push the new binaries to the device. 23# 4. Run tests with the additional environment variables: 24# * GCOV_PREFIX=/data/local/tmp/gcov 25# * GCOV_PREFIX_STRIP=`echo $(ANDROID_BUILD_TOP) | grep -o / | wc -l` 26# 5.
