Android application icon not showing up

Question

I've just spent numerous hours constructing an icon for an Android app I'm working on, but can't get it to show up for the app in the emulator.

I've put it in res/drawable-hdpi, res/drawable-mdpi, res/drawable-ldpi in the respective sizes as defined in http://developer.android.com/guide/practices/ui_guidelines/icon_design_launcher.html

The manifest contains the line:

 <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> 

Any ideas as to why it isn't showing up?

Answer 1

I would like to elaborate on the answers of @Britton Pentakill and @arnav bhartiya because I could solve my problem using their answers. I added more actions on my MainActivity because Android Studio was complaining that "App not indexable by Google" and I also wanted it to be indexable.

Wrong AndroidManifest.xml:

<intent-filter>   <action android:name="android.intent.action.MAIN"/>   <category android:name="android.intent.category.LAUNCHER"/>   <action android:name="android.intent.action.SEND"/>   <action android:name="android.intent.action.VIEW"/>   <category android:name="android.intent.category.BROWSABLE"/>   <data android:scheme="https"         android:host="siara.cc"         android:pathPrefix="/CrossCalc" />  </intent-filter> 

So when I published my app, people could not find my App Icon on their device, no Open button after installing on Play console, even if it did pass review and published on play store (it took 7 days).

Then when I read their answers, I corrected and now I am able to see the icon for opening my app:

Correct:

<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"/>   <category android:name="android.intent.category.DEFAULT"/>   <category android:name="android.intent.category.BROWSABLE"/>   <data     android:scheme="https"     android:host="siara.cc"     android:pathPrefix="/CrossCalc"/> </intent-filter>
