• 解决：修改版本与依赖

   

• 修改为：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
}

•  删除：

 

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

• 结束
