Answer 1

I did the following to make this run on AS 3.5

1. app/ build.gradle

   apply plugin: 'com.android.application'

   android { compileSdkVersion 21 buildToolsVersion "25.0.0"

   defaultConfig {
       applicationId "com.example.android.mobileperf.render"
       minSdkVersion 14
       targetSdkVersion 21
       versionCode 1
       versionName "1.0"
   }
   buildTypes {
       release {
           minifyEnabled false
           proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
       }
   }
   

   }

dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:21.0.0' implementation 'com.squareup.picasso:picasso:2.71828' }

2. build.gradle

   buildscript { repositories { jcenter() mavenCentral() maven { url 'https://maven.google.com/' name 'Google' } google() } dependencies { classpath 'com.android.tools.build:gradle:3.0.1' } } allprojects { repositories { jcenter() google() } }

3. gradle-wrapper.properties

   distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

Answer 2

For Android Studio 3 I need to update two files to fix the error:--

1. app/build.gradle

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

2. app/gradle/wrapper/gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

Answer 3

Alright I figured out how to fix this issue.

• Open build.gradle and change the gradle version to the recommended version:
  classpath 'com.android.tools.build:gradle:1.3.0' to
  classpath 'com.android.tools.build:gradle:2.3.2'
• Hit 'Try Again'
• In the messages box it'll say 'Fix Gradle Wrapper and re-import project' Click that, since the minimum gradle version is 3.3
• A new error will popup and say The SDK Build Tools revision (23.0.1) is too low for project ':app'. Minimum required is 25.0.0 - Hit Update Build Tools version and sync project
• A window may popup that says Android Gradle Plugin Update recommended, just update from there.

Now the project should be runnable now on any of your android virtual devices.
