My target SDK version is 26 but when I upload my apk on playstore, app supports only SDK ranging 16 to 19

Question

My projects Gradle file looks like this as given below.

android {
compileSdkVersion 26
buildToolsVersion "25.0.3"
defaultConfig {
    applicationId "com.abc.myappspackagename"
    minSdkVersion 16
    targetSdkVersion 26
    versionCode 8
    versionName "1.7"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
    multiDexEnabled = true
}
buildTypes {
    release {
        multiDexEnabled true
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }

    dexOptions {
        javaMaxHeapSize "4g" //specify the heap size for the dex process
    }

}

packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
    exclude 'META-INF/ASL2.0'
    exclude 'META-INF/MANIFEST.MF'
    exclude 'META-INF/notice'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/rxjava.properties'
}
}

Now when I test my app on my mobile devices (Samsung Neo [4.2] and Samsung A7 [7.0]) + emulators (different android versions) my app works as per my imagination and how it should work!

I have used few 3rd party libraries.

Now, the problem is when I upload my app on google play store, it only supports versions ranging from 4.1-4.4 (SDK 16-19) only.

What is the probllem going?

Please point me, what have I done wrong?

EDIT-1:

Have a look on my Manifest.xml

    android:minSdkVersion="16"
    android:targetSdkVersion="26"

This is how I fixed this issue. Go to: Files > Project Structure...

In the window that opens select "app" under modules. Then pick the tab flavors and set the "Target sdk Version" as 26 or more.
