新建項目時 gradle build 報錯
* 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.
按照報錯提示，百度后試了各種辦法，還是有這個錯誤，請問老師如何解決呢

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' }
