Unable to merge multidex Execution failed

I am having Error Unable to merge dex in my project.
i applied different answers from StackOverFlow like:
defaultConfig {
multiDexEnabled true
}
dependencies {
compile 'com.android.support:multidex:1.0.1'}
<application
android:name="android.support.multidex.MultiDexApplication"
and applied in manifest as well.i cleaned project Rebuild /MakeProject and applied all other option provided by users in answers but getting that error. when i enable multidex then i got list of errors converting byte to dex. I don't know what i am missing in that.
here is my App Gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.example.hp_pc.cerv"
minSdkVersion 15

}
dexOptions {
preDexLibraries = false
}
buildTypes {

}
}
packagingOptions {

exclude 'META-INF/NOTICE'
exclude 'META-INF/DEPENDENCIES'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'
// compile files('libs/httpclient-4.2.3.jar')
// compile files('libs/httpmime-4.3.jar')

}
and here is my Project Gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
maven {
url 'https://maven.google.com/'
name 'Google'
}
}
dependencies {

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
google()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

If you are using Google Service then your Project gradle should look like this-
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
google()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
And for handling the Multidexing and using Google service your App gradle should look like this-
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.example.hp_pc.cerv"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
dexOptions {
preDexLibraries = false
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
packagingOptions {
exclude 'META-INF/ASL2.0'
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
exclude 'META-INF/DEPENDENCIES'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'
// compile files('libs/httpclient-4.2.3.jar')
// compile files('libs/httpmime-4.3.jar')
// compile files('libs/httpcore.jar')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:multidex:1.0.1'
compile 'com.mcxiaoke.volley:library:1.0.+'
compile 'com.github.pinball83:masked-edittext:1.0.3'
// compile 'com.google.android.gms:play-services-maps:9.8.0'
compile 'com.android.support:design:23.4.0'
compile 'com.wdullaer:materialdatetimepicker:2.5.0'
compile 'com.google.android.gms:play-services:6.5.87'
compile 'joda-time:joda-time:2.9.4'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'
And add these two lines in your AndroidManifest file inside tag-
<application
android:hardwareAccelerated="true"
android:largeHeap="true"
hope it will resolve your problem.

ZipException: duplicate entry exception

I'm making Android chat bot app with Firebase and API.AI.
After adding firebase UI lib to project, I got java.util.zip.ZipException: duplicate entry runtime exception.After that, I've added javaMaxHeapSize = "4g" but could not find a solution for this.Tried with different FirebaseUI versions, but none of them worked.
There are other similar questions, but each is generic with different build.grade.
Here is message:
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/auth/api/signin/internal/zzf.class
Gradle files:

}
dexOptions {
javaMaxHeapSize = "4g"
}
buildTypes {

}
}

compile 'com.firebaseui:firebase-ui-database:2.3.0'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'
Second one :
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
classpath 'com.google.gms:google-services:3.1.0'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

This is happening because you are mixing the old dependencies with new ones. So in order to solve your problem, delete the following line of code from your build.gradle file.
compile 'com.firebaseui:firebase-ui-database:2.3.0'
This line of code is no needed and that's why you get duplicate entry exception. See the version compatibility for the FirebaseUI i suggest you see the offical documentation.

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 9.0.0.
thanks~

You should rectify your build.gradle
No Need
compile project(':library_googlemap') // Remove this line
Finally
compile 'com.google.android.gms:play-services-maps:10.2.1'
compile 'com.google.firebase:firebase-core:10.2.1'
compile 'com.google.android.gms:play-services-tagmanager:10.2.1'
