-A GitHub Action for installing, configuring and running Android Emulators on macOS virtual machines.
+A GitHub Action for installing, configuring and running hardware-accelerated Android Emulators on macOS virtual machines.

 The old ARM-based emulators were slow and are no longer supported by Google. The modern Intel Atom (x86 and x86_64) emulators require hardware acceleration (HAXM on Mac & Windows, QEMU on Linux) from the host to run fast. This presents a challenge on CI as to be able to run hardware accelerated emulators within a docker container, **KVM** must be supported by the host VM which isn't the case for cloud-based CI providers due to infrastructural limits. If you want to learn more about this, here's an article I wrote: [Running Android Instrumented Tests on CI](https://dev.to/ychescale9/running-android-emulators-on-ci-from-bitrise-io-to-github-actions-3j76).

+| `api-level` | Required | N/A | API level of the platform system image - e.g. 23 for Android Marshmallow, 29 for Android 10. **Minimum API level supported is 15**. |
 | `target` | Optional | `default` | Target of the system image - `default` or `google_apis`. |
-| `arch` | Optional | `x86` | CPU architecture of the system image - `x86` or `x86_64`. |
+| `arch` | Optional | `x86` | CPU architecture of the system image - `x86` or `x86_64`. Note that `x86_64` image is only available for API 21+. |
 | `profile` | Optional | N/A | Hardware profile used for creating the AVD - e.g. `Nexus 6`. For a list of all profiles available, run `$ANDROID_HOME/tools/bin/avdmanager list` and refer to the results under "Available Android Virtual Devices". |
+| `avd-name` | Optional | `test` | Custom AVD name used for creating the Android Virtual Device. |
 | `emulator-options` | Optional | See below | Command-line options used when launching the emulator (replacing all default options) - e.g. `-no-window -no-snapshot -camera-back emulated`. |
 | `disable-animations` | Optional | `true` | Whether to disable animations - `true` or `false`. |
 | `emulator-build` | Optional | N/A | Build number of a specific version of the emulator binary to use e.g. `6061023` for emulator v29.3.0.0. |
 | `working-directory` | Optional | `./` | A custom working directory - e.g. `./android` if your root Gradle project is under the `./android` sub-directory within your repository. |
+| `ndk` | Optional | N/A | Version of NDK to install - e.g. `21.0.6113669` |
+| `cmake` | Optional | N/A | Version of CMake to install - e.g. `3.10.2.4988404` |
 | `script` | Required | N/A | Custom script to run - e.g. to run Android instrumented tests on the emulator: `./gradlew connectedCheck` |

 Default `emulator-options`: `-no-window -gpu swiftshader_indirect -no-snapshot -noaudio -no-boot-anim`.

+## Can I use this action on Linux VMs?
+
+The short answer is yes but it's expected to be a much worse experience (on some newer API levels it might not work at all) than running it on macOS.

+For a longer answer please refer to [this issue](https://github.com/ReactiveCircus/android-emulator-runner/issues/46).

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.log(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# security
+
+Previous versions had a prototype pollution bug that could cause privilege
+escalation in some circumstances when handling untrusted user input.
+
+Please use version 1.2.3 or later: https://snyk.io/vuln/SNYK-JS-MINIMIST-559764
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+
+  ```
+  > require('./')('one two three -- four five --six'.split(' '), { '--': true })
+  { _: [ 'one', 'two', 'three' ],
+    '--': [ 'four', 'five', '--six' ] }
+  ```
+
+  Note that with `opts['--']` set, parsing for arguments still stops after the
+  `--`.
+
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
