Which version APK i need to upload to Play store?
<p>I am using Android Studio 2 and below is how my gradle file looks.
My application builds without any error. Now as minSdkVersion is 15 , does that means if i publish the APK from my machine, it will run well on Android SDK version 15 also ?</p>

<pre><code>apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.google.android.gms:play-services-ads:8.4.0'
}
</code></pre>
