【AndroidStudio】Error:Execution failed for task ':app:preDebugAndroidTestBuild'.

AS中解決Error:Execution failed for task ':app:preDebugAndroidTestBuild'.問題。

1、開啟對應的app中的build.gradle檔案

2、在build.gradle的dependencies依賴中增加如下配置資訊

androidTestCompile('com.android.support:support-annotations:26.1.0') { 
   force = true 
}

增加配置後的配置如下：

dependencies {
    androidTestCompile('com.android.support:support-annotations:26.1.0') {
        force = true
    }
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    implementation 'com.android.support:design:26.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
