Wrapper script to add command line options to the AVD emulator.

#
# Wrapper script to add command line options to the AVD emulator.
#
# avdmanager should support the studio.emu.params environment variable, but it doesn't handle commas well.
#
# ## Installation
#
# 1. Find your AVD home directory. It should have an `emulator` subdirectory.
# 2. Move the `emulator/emulator` file to `emulator/emulator-orig`.
# 3. Store this script as `emulator/emulator`.
# 4. After upgrades, you will have to do it all again.
#
# ## Usage
#
# Use the environment variable AVDX_EMU_PARAMS to set parameters directly.
# Or use the environment variable AVDX_EMU_PARAMS_FILE to set a file to read parameters from.
# Or add parameters directly to the params variable below.
# Do this before starting Android Studio or AVD Manager, since processes inherit environment variables from their parents.
