I am completely new to android and kotlin programming. I just started learning android since yesterday. I have successfully created a project but it doesn't show me xml editor.
Error: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.
build.gradle
buildscript {
ext.kotlin_version = '1.1.51'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Any idea to solve this problem
