Here is error log:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl.class Help me through

Below is my gradle code:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "*******"
        minSdkVersion 16
        targetSdkVersion 23
        multiDexEnabled true
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        javaMaxHeapSize "4g"
        preDexLibraries = false
    }
    packagingOptions {
        exclude 'META-INF/NOTICE.txt' // will not include NOTICE file
        exclude 'META-INF/LICENSE.txt' // will not include LICENSE file
    }
}

dependencies {
    compile fileTree(exclude: 'android-support-*.jar', dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile project(':simple-crop-image-lib')
    //    compile 'com.github.navasmdc:MaterialDesign:+'
    compile project(':material-login')
    compile 'com.android.support:multidex:1.0.1'
    compile ('com.android.support:appcompat-v7:23.4.0'){
        exclude module: 'support-v4'
    }
}

Answer 1

First Compile the build with

compile 'com.android.support:multidex:1.0.1'

In Your AndroidManifest.xml add this lines android:name

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:name="android.support.multidex.MultiDexApplication"
    >

And In your build.gradle also add

dexOptions {
    //incremental = true;
    preDexLibraries = false
    javaMaxHeapSize "4g"
}


packagingOptions {
     exclude 'META-INF/NOTICE.txt' // will not include NOTICE file
    exclude 'META-INF/LICENSE.txt' // will not include LICENSE file
}
