新建项目时 gradle build 报错

* What went wrong:

Execution failed for task ':app:preDebugAndroidTestBuild'.

> Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

按照报错提示，百度后试了各种办法，还是有这个错误，请问老师如何解决呢

在build.gradle 里面的android{}加入

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-annotations:26.1.0'
    }
}
然后加入 dependencies {
    implementation 'com.android.support:appcompat-v7:26.1.0'
}
