Some devices dont show the launcher icon

Question

Some people that use my application are complaining that after the update, the launcher icon went missing so they can't start the game. I myself don't have that problem. All ic_launcher.png images are in the drawable maps and I didn't change them.

  <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="wetenschappelijk.project"
 android:versionCode="36"
 android:versionName="3.0.0" >

<uses-sdk android:minSdkVersion="7" />
     <application
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" >

    <activity
        android:label="@string/app_name"
        android:name=".GalgjeActivity" 
        android:configChanges="orientation|keyboardHidden"
          >
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity     
        android:name=".MenuActivity" 
        />
    <activity     
        android:name=".GameActivity" 
        />

    <activity     
        android:name="wetenschappelijk.project.Settings"
        />
    <activity     
        android:name="wetenschappelijk.project.Multiplayer"
        />
    <activity android:name="com.google.ads.AdActivity"
              android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
    <meta-data android:value="a14ef899d6be24a" android:name="ADMOB_PUBLISHER_ID"/>
</application>  

Answer 1

if there is no icon name :ic_launcher.. at that time the there is default icon name :icon.png already there

Edit: As I showed in your manifest file . you didn't display API minimum version. may be that is issue:

  <uses-sdk android:minSdkVersion="8" />
