fix-android-emulator-audio

The goal of the script is to fix common Bluetooth issue when running Android Emulator on macOS. Script modifies emulator configs in batch, so you don't have to do it manually, one by one.

Installation

There're a few options to get and run the script.

1. git clone

git clone git@github.com:mrmike/fix-android-emulator-audio.git
# and call ./fix-android-emulator-audio inside repo directory

2. Homebrew

brew tap mrmike/homebrew-fix-android-emulator-audio
brew install fix-android-emulator-audio
# and call fix-android-emulator-audio from any location 

3. curl - you can use curl to get and run the script

curl -s https://raw.githubusercontent.com/mrmike/fix-android-emulator-audio/main/fix-android-emulator-audio | bash /dev/stdin

Usage

Before calling the script make sure that emulator is closed.

 fix-android-emulator-audio

# Sample output
🔊 Processing emulators from: /Users/<USERNAME>/.android/avd
🔊 Processing - Pixel_5_API_31.avd
✅ Done - Pixel_5_API_31.avd
🔊 Processing - 4.7_WXGA_API_27.avd
✅ Done - 4.7_WXGA_API_27.avd

By default script will look on emulators located at ~/.android/avd. Script accepts argument with custom avd directory localization

fix-android-emulator-audio path/to/your/avd/directory

Optionally you can pass --wipe option to wipe emulator's data so you don't have to do it manually via Android Studio. Script removes following files and directories:

* snapshots/
* userdata.img
* userdata-qemu.img

When running emulator for the first time after applying the fix make sure that data is wiped and emulator is started with Cold Boot option.

How does it works
