Show App Icon in View with Opened Apps on Android

i created a new Project with Android Studio, created a new Image Asset of the App Icon. The Icons have been saved in the mipmap folders, not as i'm used to in the drawables.
Now ia can use the App Icon as my Icon in the ActionBar etc. but when i open the view on my Smartphone which shows all running programs (dont know how this View is called) it uses the standars Android Icon, not the Icon i set.
How can i make sure that it uses my App Icon everywhere?
My AndroidManifest:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label=" Pentle" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Make sure you set the new icon in your Manifest in the <Applicaton> tag.
It should be something like this
<Application
android:icon="#drawable/your_image"
.... />

Application icon does not appear after installing android app

I am developing an android app and when I install the app on android phone, the application icon does not appears in application section. But it appears in application manager and I can make uninstallation. After googling, some said I need to rebuild my project and to make sure the app icon in drawable resource. I already tried for this solution and the problem is still occurring. The manifest file I created is as follow:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity
android:name=".MyActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.view" />
<data android:scheme="geo" />
</intent-filter>
</activity>
</application>

I believe geo scheme cannot be used with Launcher. I can't find any documentation but in this tutorial they suggest to use with default category.
Please try to move your location related code to another activity and move scheme=geo filter to that one.

In your manifest in activity try using or add another intent filter
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
`

Change
android:icon="#drawable/ic_launcher"
With your icon
if you wanna to remove this icon you have to remove from all folder like
drawable
drawable-hdpi
drawable-mdpi
drawable-xhdpi

I set action android:name="android.intent.action.MAIN and android:name="android.intent.category.LAUNCHER two of mine activity intent.For this I'm having two launcher icon.When I noticed that I remove one activity's intent filter,but My launcher icon disappear.I tried all the mentioned above solution but didn't work.As I noticed Darpan's comment about re-starting your phone will fix it I tried and It works for me

In my case, my manifest included a label for the main activity. I deleted the label, restarted the app and the icon magically appeared in the applications list.

Change icon of activity in my application specific to share

I implement an app in which is one Activity designed for sharing text. Everything works fine, text is sharing etc. But if I would like to share some text, executing share action offered some applications which can handle sharing text. There is my application but shown icon is not equal of default ic_launcher. How can I change icon of my app when system offers me apps which can handle sharing text?
thanks.

you can change your app in manifest file..
<application
android:icon="#drawable/ic_launcher" //---- here--put your new icon in drawable folders and change it here
android:label="#string/app_name" // same thing.. change your app name in string.xml file.. then, here app name will change automatically....
android:theme="#style/AppTheme" >
<activity
android:name=".ui.MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
try this..
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Activity label appears on home screen instead of app name

In AndroidManifest.xml, the application tag has:
android:label="#string/app_name"
and app_name in res/values/strings.xml reads "My App".
But after running or debugging on both the emulator and an attached device, the app icon on the home screen displays the main activity's label instead of the app label. Is this expected behavior, and if not why might it be happening?

Yes it is Expected behavior. The app name will be seen in the applications tab in settings. The main screen displays the launcher activity's label.

If you want to display the app_name property as the label of your application below the launcher icon you can specify the android:label property in the application tag of your android manifest file.
For example:
<application
android:name=".MyApp"
android:icon="#drawable/myIcon"
android:label="#string/app_name">

A workaround for this behaviour:
In manifest:
<application
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
In MainActivity's onCreate:
getSupportActionBar().setTitle(R.string.activity_name);
By doing this, the app name will appear on home screen, and you can still have a different title for your launcher activity.

People see here, I got the same issue and finally resolve it.
Launcher show only the mainActivity because activity label is preferred for Phone Launcher.
So one want show Application labe rather than MainActivity's, he should delete the line:
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter android:label="#string/app_name" >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
delete this:
android:label="#string/title_activity_main"
