Error While using FIngerprintManager android API

Question

I am trying to use the new Fingerprint Scan feature on android. I followed the google's example from here: https://github.com/googlesamples/android-FingerprintDialog

But when I run my program I get this error:

I tried to find the solution of this issue on google, but it didn't help. Few SO question pointed out mistake n gradle file, so my app gradle file looks like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "ivote.android.gj.ivote"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    jcenter()
    mavenCentral()
    maven { url "https://jitpack.io" }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.android.support:support-v4:23.1.1'
    compile "com.android.support:support-v13:23.1.1"
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile project(path: ':volley')
    compile 'com.android.support:cardview-v7:23.1.1'
    compile 'com.android.support:recyclerview-v7:23.1.1'
    compile 'com.github.PhilJay:MPAndroidChart:v2.2.3'
    compile 'com.journeyapps:zxing-android-embedded:3.0.2@aar'
    compile 'com.google.zxing:core:3.2.0'
}

I am trying to solve this error for a while, so please if any one can help it would be great help. Thanks in Advance!

Try to reduce the amount of libraries you are using, or use multidex in your application. I would expect you have reached the 65k method count limit.

FingerprintManager is supported in API 23 and Higher. Your App's minimum SDK support is 15.
If your app is running on the device with Android version older than Marshmellow then you need to use FingerprintManagerCompat otherwise you will encounter above exception.
