The app i developed doesn't open when I click on it

I developed an android application and today I released a new version of my application. But there is no application icon in my phone. Even if I enter the google play store it doesn't open. How can that be?

<application
        android:allowBackup="true"
        android:icon="@drawable/minik"
        android:label="@string/app_name"
        android:enabled="false"
        android:roundIcon="@drawable/minik"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"> ...
   </application>

Changing from 

<activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
            <action android:name="android.intent.action.VIEW"></action>

            <category android:name="android.intent.category.DEFAULT"></category>
            <category android:name="android.intent.category.BROWSABLE"></category>

            <data
                android:host="www.example.net"
                android:scheme="https"></data>
        </intent-filter>

    </activity>

to this

<activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

            <action android:name="android.intent.action.VIEW"></action>

            <category android:name="android.intent.category.DEFAULT"></category>
            <category android:name="android.intent.category.BROWSABLE"></category>

            <data
                android:host="www.example.net"
                android:scheme="https"></data>
        </intent-filter>

    </activity>

solved my problem.

Did you define launcher activity in AndroidManifest.xml inside <application>...</application>?

<activity
    android:name=".ui.MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

To make your app launchable, show Open button in Play store and show an icon in phone launcher you should define an activity with intent category LAUNCHER

To launch an activity on clicking App Icon your App must have an activity with category "Launcher".

Have a look at example below,

You hadn't even mentioned your activity name in your AndroidManifest.xml.

Please try to write as below, and your problem will be resolved.

 <application
    android:allowBackup="true"
    android:icon="@drawable/minik"
    android:label="@string/app_name"
    android:enabled="false"
    android:roundIcon="@drawable/minik"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

        <activity
            android:name=".ui.SplashActivity"   //mention your activity to be launched
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
 </application>
