[Android Setup] - Detox can't seem to connect to the test app(s)

[mackwill]

Description

So im setting up detox in our project - and everything seems to be running smoothly on iOS

On android however, i cannot seem to get the tests to run at all. I can build just fine, but when i try to run a test, this is the error that i get. (Currently on APK level 33)

HINT: 

Have you forgotten to call 'device.launchApp()' in the beginning of your test?

There have been a number of issues opened about this and i have tried all of the available solutions but have had no success in getting things to run.
I know that there isn't officially support for RN 0.72 yet, but i want to know if anyone has had any success on this version of RN, or if it really is just the version that im on that's causing the issue.

note my current folder structure is

root/
-- node_modules
--src
--ios
--android
--e2e (detox is in here)

Here's the android section of the .detoxrc file

  apps: {
    "android.dev.debug": {
      type: "android.apk",
      binaryPath: `../android/app/build/outputs/apk/dev/debug/app-dev-debug.apk`,
      testBinaryPath: `../android/app/build/outputs/apk/androidTest/dev/debug/app-dev-debug-androidTest.apk`,
      build: `cd ../android && ./gradlew app:assembleDevDebug app:assembleDevDebugAndroidTest -DtestBuildType=debug && cd ..`,
    },
  },

in my build.gradle file

allprojects {
    repositories {
        google()
        maven {
            url("$rootDir/../e2e/node_modules/detox/Detox-android")
        }
        maven { url "https://jitpack.io" }
    }
}

And at the beginning of my tests, i have the call for deviceLaunch in my beforeAll - i know that the tests themselves are fine because i run them on iOS no problem.
I can't really pinpoint where the issue is now, but as i said i've tried other solutions like adding testBinaryPath and tweaking my android/app/build.gradle file to the following like some other suggestions here

    androidTestImplementation('com.wix:detox:+') {
        exclude module: "protobuf-lite"
    }
    implementation 'androidx.appcompat:appcompat:1.1.0'

Any help here would be appreciated.

The same for me...can't figure out where the problem is

[mackwill]

yeah - seems to be a common issue but would love some support for this. Its definitely impeding rollout of testing if we can't get it up and running on android

[drajnamichal]

any news @mackwill ?

[only1chi]

I have the same problem. Does anyone have any solution? This happens on the Github runner, but I can run detox locally on my M1 machine.
