Answer 1

After Everybody's help, I could resolve this issue & run app in lower version.

My updated build.gradle is like below.

Special thanks to all Genius out there!

apply plugin: 'com.android.application'
android.buildTypes.each { type ->
    type.buildConfigField 'String', 'Base_URL', WEBServiceBaseURL
    type.buildConfigField 'String', 'SMS_Base_URL', WEBServiceBaseSMSURL
}

android {
    compileSdkVersion 27
    buildToolsVersion "26.0.2"
    defaultConfig {
        applicationId "com.dummy.dummy"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled  true
    }
    buildTypes {
        release {
            minifyEnabled true
            shrinkResources 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-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:26.+'
    compile files('libs/jxl-2.6.jar')
    compile 'com.google.gms:google-services:+'
    compile 'com.google.firebase:firebase-core:11.8.0'
    compile 'com.google.firebase:firebase-messaging:11.8.0'
}

apply plugin: 'com.google.gms.google-services'
