Icon launcher generated via Playstore is restarting my app on Android 4.4

Question

i have an strange issue,

My Icon launcher generated via Plays Store installation is restarting my app, it happens when my app is in background, however my Icon launcher inside my "Apps" sections just open the application on a normal way.

this only happen with my signed app downloaded from Playstore, what would be the reason for that restarting caused by the Play Store´s icon launcher?

I have realized it only happens with Android 4.4 "Kit Kat"

this is my AndroidManifest.xml :

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.jorgesys.news"
    android:versionCode="41"
    android:versionName="2.7.7" >

    <uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="19" />

    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />

        android:required="false" />
    <uses-feature
        android:name="android.hardware.wifi"
        android:required="false" />

    <application
        android:name="com.jorgesys.news.MyApplication"
        android:allowBackup="false"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppBaseTheme" >
       <activity
            android:name="com.jorgesys.news.MainActivity"
            android:label="Jorgesys"
            android:launchMode="singleTask"
            android:windowSoftInputMode="adjustPan"
            android:configChanges="keyboardHidden|orientation|screenSize">
            <meta-data
                android:name="android.app.default_searchable"
                android:value="com.jorgesys.news.activities.SearchableActivity" />
        </activity>


     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

    </application>

</manifest>

hoping to have some help from the experts! thanks in advance!

You might have stumbled upon an known issue in Android. Issues: 2373 , 5277

Here is a fix you can try from a similar question that got more attention:

if (!isTaskRoot()
            && getIntent().hasCategory(Intent.CATEGORY_LAUNCHER)
            && getIntent().getAction() != null
            && getIntent().getAction().equals(Intent.ACTION_MAIN)) {

        finish();
        return;
    }

If this instance is opened by the launcher but it's not the root of the task (you have other activities open) then closing it should bring up the last open activity.
