Answer 1

Upgrade to Android Studio 3.3 destroyed all my projects.

This was one of the problems today I ran into. And after wasting too much time to find a solution, here is the working gradle. By the time I fixed this, I had forgotten what actually I was working on. I really wonder why Google always ship their Android Studio with broken gradle files. Seems like Google engineers even themselves don't know how to write proper gradle, and nobody QAs Android Studio before its final release.

Module level gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27

    defaultConfig {
        applicationId "com.journaldev.okhttp"
        minSdkVersion 25
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:design:27.1.1'
    testImplementation 'junit:junit:4.12'
    implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
}

And the project level gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.google.com/' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
