问题描述

Warning:Conflict with dependency 'com.android.support:support-annotations' in project ':xxx'. Resolved versions for app (25.4.0) and test app (27.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

　　问题的意思就是说不能解决 25.4.0 和 测试 27.1.1 应用之间的差异，就是说 com.android.support:support-annotations 版本冲突了。

问题解决

　　在 build.gradle 添加

android {
	...
}
configurations.all {
	resolutionStrategy.force 'com.android.support:support-annotations:27.1.1'
}
dependencies {
	...
}

　　resolutionStrategy.force 是强制依赖的意思。
