At first I had only ANDROID_HOME set, but once I've added $ANDROID_HOME/platform-tools to the path I could get rid of this error.

I am having a similar error while Detox is trying to install the APK on the emulator

ChildProcessError: Command failed: /Users/user/Library/Android/sdk/platform-tools/adb -s emulator-5556 install -r -g /Users/user/workspace/mobileTech/android/app/build/outputs/apk/debug/app-debug.apk adb: failed to install /Users/user/workspace/mobileTech/android/app/build/outputs/apk/debug/app-debug.apk: Failure [INSTALL_FAILED_TEST_ONLY: installPackageLI] ``/Users/user/Library/Android/sdk/platform-tools/adb -s emulator-5556 install -r -g /Users/user/workspace/mobileTech/android/app/build/outputs/apk/debug/app-debug.apk (exited with error code 1)

I have tried adding platform-tools to the path to no avail. Perhaps I am not doing it properly. If this is truly the solution I would appreciate a guide for doing this. Thanks.

@ararog anymore details on what you did?
I have this?
export PATH="$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools:$PATH"

[ararog]

@evanjmg this line was more than enough to get detox started working for me.

I have this and it's sourced with my zshrc and it still cannot find my avd and it's still using the wrong path - version detox 6.0.4, gradle 2.4.1, react native 0.52.1. Detox build runs fine, but detox test errors

     ChildProcessError: Command failed: /usr/local/opt/android-sdk/tools/emulator -list-avds --verbose
/bin/sh: /usr/local/opt/android-sdk/tools/emulator: No such file or directory
 `/usr/local/opt/android-sdk/tools/emulator -list-avds --verbose` (exited with error code 127)
