Answer 1

Use this build.gradle in your project

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.fileobserver"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Top level build.gradle downgrade version 
buildscript {
    ext.kotlin_version = '1.3.31'
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        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
    }
}

I had a same problem. Currently,the best option is to downgrade your class path to the last stable version. For me, i changed my class path to *classpath 'com.android.tools.build:gradle:3.3.2'*and it worked for me. In Android studio 3.4, you can easily downgrade Android Gradle Plugin Version.

1. Go to File->Project-Structure->Project
2. Change Android Gradle Plugin Version to 3.3.2 or the last stable version for you
3. Change the Gradle Version to 4.10.1
4. Click Ok and sync
5. Build Apk

Edit (Issue solved): Installing Service pack 1 for window 7 solved the issue. The problem was with Universal C Runtime in Windows.
