Build release mode in Android studio [duplicate]

Question

Earlier my gradle was like this: WHICH IS OFCOURSE INCORRECT

    apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.3'

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:gridlayout-v7:19.0.1'
    compile 'com.android.support:appcompat-v7:+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:+'
    compile 'com.google.android.gms:play-services:+'
    compile 'com.jakewharton:butterknife:4.0.+'
    compile 'com.google.code.gson:gson:2.2.+'
    compile 'com.google.android.gms:play-services:+'
}

So while uploading i got an error from google play saying that the apk is still in debug mode and could not allow to upload that apk.

Now after searching over, I found that i need to change my gradle file finally i have come up with this gradle:

Please guide me if i am correct!!

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.3'

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }

    signingConfigs {
        release {
            storeFile file("F:\\MyAppFolder\\AppName.jks")
            storePassword "abc1236"
            keyAlias "prince"
            keyPassword "abc1236"
        }
    }
}

dependencies {
    compile 'com.android.support:gridlayout-v7:19.0.1'
    compile 'com.android.support:appcompat-v7:+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:+'
    compile 'com.google.android.gms:play-services:+'
    compile 'com.jakewharton:butterknife:4.0.+'
    compile 'com.google.code.gson:gson:2.2.+'
    compile 'com.google.android.gms:play-services:+'
}

Now where am i going wrong?

Please help.

On the lower left of the Studio window there's a docked view called "Build Variants".

Open it and choose the release variant.

ps. you are adding compile 'com.google.android.gms:play-services:+' twice.
