[FIXED] on latest android the app icon starts new activity

Issue

After testing my application on multiple device i found out that on some of them if i click application icon it shows me WelcomeActivity instead of bringing back the application from background. I know that WelcomeActivity is LAUNCHER but on my other devices the app icon alway bring me back the background application.

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:launchMode="singleTop"
        android:noHistory="true"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
<activity
            android:name=".WelcomeActivity"
            android:screenOrientation="portrait"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar"
            android:windowSoftInputMode="adjustPan">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme"
            android:windowSoftInputMode="adjustPan">

After WelcomeActivity i use MainActivity. and usually the app is putted to the background while that was alive.

Solution

Remove

 android:launchMode="singleTop"

Because

If an instance of the activity already exists at the top of the target task, the system routes the intent to that instance through a call to its onNewIntent() method, rather than creating a new instance of the activity.
