I'm using android studio 3.1.0.
Please help.
Thanks.

What I have tried:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "com.hataflabs.batterywidget"
        minSdkVersion 18
        targetSdkVersion 27
        versionCode 1
        versionName "260816"
    }
    repositories {
        mavenLocal()
        mavenCentral()
        google()
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:27.0.0'
    implementation 'com.android.support:appcompat-v7:27.0.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
