Android masquer / afficher l'icône de l'application par programme

j'avais utilisé ci-dessous le code pour l'icône de l'application masquer par programme

try{
    PackageManager p = getPackageManager();
    p.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}catch (Exception e) {
    e.printStackTrace();
}

Maintenant, je veux rendre l'icône visible par programme

Masquer l'icône de l'application en utilisant le code ci-dessous:

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); // activity which is first time open in manifiest file which is declare as <category Android:name="Android.intent.category.LAUNCHER" />
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

Voici comment ramener l'icône de l'application.

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

Meilleure façon de masquer l’icône d’application du lanceur que vous pouvez utiliser <category Android:name="Android.intent.category.LEANBACK_LAUNCHER"/> Dans votre manifeste MainActivity

  <activity Android:name=".MainActivity">
        <intent-filter>
            <action Android:name="Android.intent.action.MAIN" />
            <category Android:name="Android.intent.category.LEANBACK_LAUNCHER"/>
        </intent-filter>
    </activity>

ajouter également une fonctionnalité use

<uses-feature
    Android:name="Android.software.leanback"
    Android:required="true" />

Pour masquer l'icône, utilisez ceci:

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); 
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

et pour afficher l'icône:

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

IMPORTANT: C'est un peu difficile si vous devez faire quelque chose avec l'activité principale de votre application lorsqu'elle est masquée. vous ferez face à un ActivityNotFoundException. pour que cela fonctionne, vous devez afficher l’icône avant de faire quoi que ce soit pour votre activité principale et la cacher à nouveau une fois que vous avez terminé.
étapes simples: 1 appel reçu ici
Icône 2-dévoiler
Activité principale de 3 lancements
4-faites vos choses sur l'activité principale
5-hide icon again

Il suffit d'utiliser le code suivant.

 PackageManager p = getPackageManager();
 ComponentName componentName = new ComponentName("com.example.removeicon","com.example.removeicon.LauncherActivity");
 p.setComponentEnabledSetting(componentName , PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

Notez que l'icône peut ne pas avoir disparu avant le prochain redémarrage.
