I got the same probleme,when I add the following code in my app's build.gradle within android { },that's ok. configurations.all { resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.1' } you can get reason in this page

You need to add this line to your dependencies:

androidTestCompile 'com.android.support:support-annotations:25.0.0'

to force using the latest version of library

You can also try to exclude conflict packages like I did for espresso-contrib library

dependencies {
    ext.JUNIT_VERSION = '4.12'
    ext.AA_VERSION = '4.0.0'
    ext.SUPPORT_VERSION = '24.1.1'
    ext.ESPRESSO_VERSION = '2.2.2'

...

    androidTestCompile "com.android.support:support-annotations:$SUPPORT_VERSION"
    androidTestCompile "com.android.support.test.espresso:espresso-core:$ESPRESSO_VERSION"
    androidTestCompile 'com.android.support.test:runner:0.5'
    androidTestCompile "com.android.support.test.espresso:espresso-intents:$ESPRESSO_VERSION"
    /**
     * AccessibilityChecks
     * CountingIdlingResource
     * DrawerActions
     * DrawerMatchers
     * PickerActions (Time and Date picker)
     * RecyclerViewActions
     */
    androidTestCompile("com.android.support.test.espresso:espresso-contrib:$ESPRESSO_VERSION") {
        exclude group: 'com.android.support', module: 'appcompat'
        exclude group: 'com.android.support', module: 'support-v4'
        exclude group: 'com.android.support', module: 'support-v7'
        exclude group: 'com.android.support', module: 'design'
        exclude module: 'support-annotations'
        exclude module: 'recyclerview-v7'
    }

This happen because of library version conflict in the debug app and test app. Add this under android{} tag

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-annotations:24.1.1'
    }
}
