Detox build fails on Android: Error while dexing

Question

I can't get past detox build on a brand new Expokit project. The build fails on these tasks:

> Transform full.jar (project :unimodules-core) with DexingTransform
AGPBI: {"kind":"error","text":"Default interface methods are only supported starting with Android N (--min-api 24): java.util.List org.unimodules.core.interfaces.Package.createExportedModules(android.content.Context)","sources":[{}],"tool":"D8"}

Here's my config (works fine on iOS):

"detox": {
  "configurations": {
    "ios.sim.debug": {
      "binaryPath": "/Users/clementdebellefroid/Library/Developer/Xcode/DerivedData/detox-test-bdznjcaewoobdcfdwtdisdwidhjo/Build/Products/Debug-iphonesimulator/detox-test.app",
      "build": "xcodebuild -workspace ios/detox-test.xcworkspace -scheme detox-test -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
      "type": "ios.simulator",
      "name": "iPhone SE"
    },
    "android.device.debug": {
      "binaryPath": "android/app/build/outputs/apk/debug/app-debug.apk",
      "build": "cd android && ./gradlew assembleDebug assembleAndroidTest -DtestBuildType=debug && cd ..",
      "type": "android.attached",
      "name": "HYF0219402003939"
    }
  },
  "test-runner": "jest"
},

Reproduce

Run expo init to create a new project
Run expo eject make it an expokit project
cd into your project, run yarn && cd ios && pod install
Follow the steps to configure detox
Add the android.device.debug config
Run detox build -c android.device.debug

Here's a repo to help reproduce the issue: https://github.com/clems36/detox-test

Environment:

Detox: 14.0.3
React Native: 0.59.8
Node: v12.9.0
macOS: Mojave 10.14.6

This might not be directly related to Detox but i assume it affects anyone who creates an expokit project.

I faced the same issue and was able to solve it by limiting the gradlew tasks to the app project.

package.json:

  ...
  "detox": {
    "configurations": {
      ...
      "android": {
        "binaryPath": "android/app/build/outputs/apk/debug/app-debug.apk",
        "build": "cd android && ./gradlew app:assembleDebug app:assembleAndroidTest -DtestBuildType=debug && cd ..",
        "type": "android.emulator",
        "name": "Nexus_5X_API_26"
      }
    },
    ...
  }

I'm not 100% sure why, but limiting tasks as Cyril pointed out worked for me – Americo Savinon Feb 24 '20 at 21:05
Cyril's suggestion, fixed my issue too. – Jeton Feb 25 '20 at 14:17
Worked for me as well – Ryker Aug 06 '21 at 20:50
Worked for me. I worked for several days tracking down this error and you have the solution. Thank you! – Alex Harrison Sep 11 '22 at 16:21

If you can change your configuration along with the changes that @Cyril Limam recommended, you will prevent the other problem you will face after figuring out above issue.

 "android.debug": {
      "type": "android.apk",
      "binaryPath": "android/app/build/outputs/apk/debug/app-x86-debug.apk",
      "testBinaryPath": "android/app/build/outputs/apk/androidTest/debug/app-debug-androidTest.apk",
      "build": "cd android && ./gradlew app:assembleDebug app:assembleAndroidTest -DtestBuildType=debug && cd .."
 }

Please be sure that binaryPath indicates your app APK's path and testBinaryPath indicates your androidTest APK's path.

I tried this command and the build Passed

cd android ; ./gradlew app:assembleRelease app:assembleAndroidTest -DtestBuildType=release ; cd -

Do the same for debug build. Add app before assembleRelease and assembleAndroidTest
