Cannot resolve symbol AndroidJUnit4 about advancedandroid_teatime

[stevenberdak]

Please step through each step carefully and in order. Allow each one time to build before going to the next:

(1) Delete your current project folder and create a new clone of the AdvancedAndroid_TeaTime repository and open the branch you are on.

(2) Do not upgrade your gradle version, click on 'do not remind me again for this project'

(3) Add these dependencies to your app level 'build.gradle' file:

    compile 'com.android.support.test.espresso:espresso-idling-resource:2.2.2'

    androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.2'
    androidTestCompile 'com.android.support.test:rules:0.5'
    androidTestCompile 'com.android.support.test:runner:0.5'

(4) Add this to your app level 'build.gradle' file outside of any brackets:

configurations.all {
    resolutionStrategy {
        forcedModules = ['com.android.support:support-annotations:25.1.0']
    }
}

(5) Add maven.google repository in your project level build.gradle file:

example:

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

(6) Rebuild the project

(7) Under the gradle menu on the right expand 'AdvancedAndroid_TeaTime(root)' and under Tasks > build, click on assembleAndroidTest

(8) Try to add AndroidJUnit4.class to a test class.

I found it. All I had to do was running the tests. Sorry, my bad.

Got the same error.

Adding in app's build.gradle the following worked for me:

testCompile 'com.android.support.test:rules:1.0.1'
testCompile 'com.android.support.test:runner:1.0.1'

but still, I'm not able to run the test. Even though I upgraded all dependencies to the latest.

Exactly, steps followed by @stevenberdak is already done and if you see AndroidJUnit4 error, just click on the green play button on left of public class IdlingResourceMenuActivityTest and it works after it installs itself on your phone :)

@stevenberdak
Thank you! you're a life Saver. 👍

@stevenberdak Thank you so much for the solution. Works perfectly. Had I not found this, I was on the verge of re-installing Android Studio itself!

Just a quick update, the above instructions seems to work well but you can also try this if you like:

I had the same problem and I was able to fix it by adding these to my app build.gradle. Note the exclude group.
Pedram [12:12 PM]
testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:rules:1.0.2'
   androidTestImplementation 'com.android.support.test:runner :1.0.2'
   androidTestImplementation('com.android.support.test.espresso:espresso-core:3.0.2', {
       exclude group: 'com.android.support', module: 'support-annotations'
   })

still not working

[silentLOL]

same here --> it's not working

[stevenberdak]

Did you start from a fresh clone?

Waheguru ji
Works great!

[nirmaljeffrey]

@stevenberdak Thanks a lot! I lost my patience on this problem for the last two days. You are my saviour!!!

[wafaaHilmy]

@stevenberdak please could you explain this step i cant understand it
(7) Under the gradle menu on the right expand 'AdvancedAndroid_TeaTime(root)' and under Tasks > build, click on assembleAndroidTest

[stevenberdak]

I haven't used Android Studio in awhile as I do web dev now, and I also know Android Studio has had updates but... There was a Gradle menu that popped out from the right side of the screen with Gradle tasks. It should be somewhere in the program if it is no longer there... and you would click on the task mentioned above (assembleAndroidTest) to trigger Gradle to perform the task which would complete the step. Hope this helps!

Currently (in the version androidx.test:runner:1.3.0) androidx.test.runner.AndroidJUnit4 is deprecated and thus is recommended to use androidx.test.ext.junit.runners.AndroidJUnit4 instead.

In order to setup this dependency declare androidTestImplementation 'androidx.test.ext:junit:1.1.2'.

You can also rely on the guide to set up a project with AndroidX Test.

@filipebezerra I tried to apply your advice to a usual Android project and got an exception when ran tests:

Test running failed: Instrumentation run failed due to 'java.lang.NoSuchMethodException'

androidx.test.runner.AndroidJUnit4 is not deprecated. :)
