Copy database from actual device to VM for testing

copy-database-to-vm.sh

# Ensure all AVDs are closed, and your Android device is connected.
# To make a backup of the ca.mattcudmore.day2day app:
~/Library/Android/sdk/platform-tools/adb backup -f backup.ab ca.mattcudmore.day2day

# Convert the backup file to TAR:
dd if=backup.ab bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" > backup.tar
# Extract the TAR to access files.
tar -xvf backup.tar

# Now disconnect Android device and launch AVD where files will be copied to.
# For copying a database file from the extracted TAR into place, for example:
~/Library/Android/sdk/platform-tools/adb push example.db /data/data/ca.mattcudmore.day2day/databases/example.db
