Hi,
I tried to run hello world program using tutorial kart. The link is:

It does not ask to write any code nor does it ask for altering any built in code. I ran it by connecting both by mobile phone and using emulator.
Error log when connected to mobile ph:
“Session app” Error installing APK
Error log file shows :
12:30 PM Gradle build finished in 21s 332ms

12:33 PM Instant Run is not supported on devices with API levels 20 or lower.
(Don't show again)
12:33 PM Executing tasks: [:app:assembleDebug]
12:34 PM Gradle build finished in 1m 33s 345ms
12:34 PM Session 'app': Error Installing APK

Error log file when connected to emulator:
Error log file while running using an emulator (visual studio android 23 arm ph)
12:34 PM Session 'app': Error Installing APK

12:44 PM Executing tasks: [:app:assembleDebug]

Also another run:

Files:
activity_main.xml

main_activity.kt

package com.example.hp.kotlinandroiddemotk

import android.support.v7.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
}

}
