在引入最新Espresso時

 androidTestCompile('com.android.support.test.espresso:espresso-core:3.0.1')

報錯：

Error:Conflict with dependency 'com.android.support:support-annotations' in project ':wisdom'. Resolved versions for app (25.3.1) and test app (25.4.0) differ

解決方案：統一更新最新support包到25.4.0

 compile 'com
 
.android.support:appcompat-v7:25.4.0'
 compile 'com.nineoldandroids:library:2.4.0'
 compile 'com.android.support:support-v4:25.4.0'
 compile 'com.android.support:recyclerview-v7:25.4.0'
