Detox + android Compiling DetoxTest.java fails

Question

I'm trying to run

detox build -c android.emu.release

but it fails when it tries to compile DetoxTest.java with the following errors

  ~/android/app/src/androidTest/java/<package_name>/DetoxTest.java:24: error: cannot find symbol
    public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(MainActivity.class, false, false);
                            ^
      symbol:   class MainActivity
      location: class DetoxTest

  ~/android/app/src/androidTest/java/<package_name>/DetoxTest.java:24: error: cannot find symbol
    public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(MainActivity.class, false, false);
                                                                                 ^
  symbol:   class MainActivity
  location: class DetoxTest

I tried importing MainActivity from the package but I get the package cannot be found.

RN 0.51.1 Detox: 7.4.3

Have you ever managed to fix this? I have the same problem with detox 8.1.5 and react native 0.56 — terreb, Aug 14 '18 at 08:11
Never mind, this is just me, I forgot to change package com.example at the top to my package name. — terreb, Aug 14 '18 at 08:17

To solve this issue, follow closely the README for wix/detox/AndroidSupportStatus

For example if your project name is myandroidproject (see property rootProject.name of settings.gradle below), DetoxTest.java will be at the following location inside the package com.myandroidproject.

android/app/src/androidTest/java/com/myandroidproject/DetoxTest.java

package com.myandroidproject

...

settings.gradle

rootProject.name = 'myandroidproject'

...

In your case above, you have to replace package_name appropriately.

Another issue can be if the rootProject.name has capital letters, like rootProject.name = 'SomeName'. Then it should be package com.somename

Along with making sure my project name was correct in my import statements, I also had to change my directories to match my package name. Somehow I was able to build the project with a folder name different than my project name in the past but detox wasn't okay with this.

Import statement:

package com.my_package_name

Corresponding folder structures:

android/app/src/main/java/com/my_package_name
android/app/src/androidTest/java/com/my_package_name
