Conflict with dependency 'com.android.support:support-annotations'. Resolved versions for app (23.3.0) and test app (23.1.1) differ

Question

I came across this exception while adding espresso to an android project. I already try the link that comes with this exception

**Conflict with dependency \'

Nowadays when you create a new project on Android Studio, it adds this dependency by default:

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})

The exclude section is probably to avoid the conflict mentioned in the question. I also faced this issue when trying to add runner:0.5 and rules:0.5 dependencies. My solution was to apply the same piece of code above on them:

androidTestCompile ('com.android.support.test:runner:0.5', {
    exclude group: 'com.android.support', module: 'support-annotations'
})

androidTestCompile ('com.android.support.test:rules:0.5', {
    exclude group: 'com.android.support', module: 'support-annotations'
})

It works for me. Hope it helps.
