Automatically added ConstraintLayout dependency in

Question

Just I update my studio (version 2.3) and build version ('25.0.0'),

now, when i try to create new activity then automatically constraintlayout dependency added in my build.gradle file.

and layout render as parent ConstraintLayout, can anyone know how to remove this dependency when activity is created.

Before activity creation gradle code.

dependencies {
  compile 'com.android.support:support-v4:23.2.1'
}

After activity creation gradle code.

dependencies {
  compile 'com.android.support:support-v4:23.2.1'
  compile 'com.android.support.constraint:constraint-layout:1.0.0'
}

You can modify default template layout file in Android Studio resources, path to it:

C:\Program Files\Android\Android Studio\plugins\android\lib\templates\activities\common\root\res\layout

Edit file simple.xml.ftl and change layout to your choice, notice that some layouts require additional elements (e. g. LinearLayout needs android:orientation), save file and create activity in Android Studio, it should work.

Mine looks like this (I have 2.2.3 so I have RelativeLayout)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
<#if hasAppBar && appBarLayoutName??>
    xmlns:app="http://schemas.android.com/apk/res-auto"
</#if>
    android:id="@+id/${simpleLayoutName}"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
<#if hasAppBar && appBarLayoutName??>
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:showIn="@layout/${appBarLayoutName}"
</#if>
    tools:context="${relativePackage}.${activityClass}">

<#if isNewProject!false>
    <TextView
<#if includeCppSupport!false>
        android:id="@+id/sample_text"
</#if>
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!" />
</#if>
</RelativeLayout>
