ZERO Device support showing in google app store for my application

Question

I have developed an app in Android Studio. It works fine on debug mode. I have tested it on many devices it works great. But when push it on Google App store it show me zero device support for my apk.

Let me tell you how i generate my apk

1. Make a keystore
2. Enter key store and key password
3. select release mode in built type
4. build the apk

I know this question is asked multiple time on this forum but none of them have satisfactory answer that's why I ask it hare again please help

Here is my manifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="ca.xyz.wk"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

    <application
        android:name="ca.xyz.wk.app.AppController"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="ca.xyz.wk.LoginActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity android:name="ca.xyz.wk.MainActivity"/>
        <activity android:name="ca.xyz.wk.ForgotPasswordActivity"/>
        <activity android:name="ca.xyz.wk.UserRegistrationActivity"/>


    </application>

</manifest>

And this is my build.grandle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "ca.xzy.wk"
        minSdkVersion 11
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile files('libs/volley.jar')
    compile 'com.android.support:support-v4:22.2.0'
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.roomorama:caldroid:2.0.1'
    compile 'org.apache.directory.studio:org.apache.commons.io:2.4'

}

I have found a solution . What I have done I simply remove all my library one by one and test the application and I found that the last library i.e 'org.apache.directory.studio:org.apache.commons.io:2.4' causing the problem. I don't know why but after removing this library google app store accept my apk and show supported device for that. Since I use Volley library to do network request so I edit my code that use apache.commons.io and my application work fine. That all how I found solution. I hope someone will benefited with it.
