Detox: Unclear Android setup instructions/ proguard

[hkung77]

Description

I've been following this for a while but everytime I try to set up android it's unclear and I haven't been very successful.
Current state of detox is suppose to support android <=0.56, but I see it seems not completely true from this

I'm also confused with how I'm suppose to add dependencies.
androidTestImplementation(project(path: ":detox"))
or
androidTestCompile(project(path: ":detox", configuration: "oldOkhttpDebug"), { exclude group: 'com.android.support', module: 'support-annotations' })

• Detox: 9.0.4
• React Native: 0.57
• Node: 8.9.1

Device and verbose Detox logs

When I try to run detox build -c android.emu.debug I get proguard errors:

Note: there were 27 duplicate class definitions.

Hi @hkung77, you might want to look at this repo: https://github.com/semutmerah/rn-56-test-detox
This example is working fine on Mac machine, and able to run both iOS and Android test.

Also, as far as I know, RN 57 is not yet supported.

@semutmerah thanks a lot for the repo! I was getting an error about cannot find symbol because I didn't import my app MainActivity in the DetoxTest.java file.

@semutmerah The issue is about ProGuard errors. You don't face them in the repo you mentioned because ProGuard is disabled in there (see https://github.com/semutmerah/rn-56-test-detox/blob/master/android/app/build.gradle#L94).

I am also facing these ProGuard issues.

[fdnhkj]

I solved my issues by using a different ProGuard file for testing via testProguardFile.

_android/app/build.gradle_

android {
    // ...
    defaultConfig {
        // ...
        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        testProguardFile 'proguard-test-rules.pro'
        testBuildType System.getProperty('testBuildType', 'debug')
        missingDimensionStrategy "minReactNative", "minReactNative46" //read note
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

_android/app/proguard-test-rules.pro_

# Proguard rules that are applied to your test apk/code.
# https://github.com/googlesamples/android-testing-templates/blob/master/AndroidTestingBlueprint/app/proguard-test-rules.pro

Hoping it helps others as well!

You're all right, we need to revamp the Android setup docs.
