Error hiding app icon after asking permitions in Android Manifest xml

I made an app to automatically hide its icon after launched.
I used this code to make this system
PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
Everything works fine until I try to request permissions in my Android Manifest XML,
for example
<uses-permission android:name="android.permission.SEND_SMS" />
on asking the permission the app ignores the script and it doesn't hide the icon
Note: the only error is that my app doesn't hide, the rest of the app works perfectly.

Android: How to unhide app

I want to allow the users of my Android app to hide/unhide it when they want.
I already have the code to perform the hide/unhide actions, and the hiding works fine.
But now how can I call the unhide method to let the app back?
I mean, if the app is hidden, where can the user, let's say, "click a button" that calls the method to make the app unhide?
Here is my hide/unhide code:
// method to hide the app icon
public static void hideAppIcon(final Context context)
{
PackageManager p = context.getPackageManager();
// activity which is first time open in manifest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
ComponentName componentName = new ComponentName(context, SplashActivity.class);
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}
// method to unhide the app icon
public static void unhideAppIcon(final Context context)
{
PackageManager p = context.getPackageManager();
// activity which is first time open in manifest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
ComponentName componentName = new ComponentName(context, SplashActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
}

Here's a way I've learned from another app. Not "hiding" the icon, instead, change the icon and label of your app. Disguise the app as some built-in apps like "Settings" or "Calculator".
Another solution (which might be closer to your need) is to add an intent-filter in your app, detecting something like phone calls. If users call a certain number, you unhide your app.

Hope this will help.

hide application icon in menu of android phone

I am new at android. I want to hide my application icon from main menu at the run time. I believe that a manifest file is responsible for the application's presence in the main menu. But I want my application in running process while switching on android phone. But it doesn't show the application icon in menu at phone.
Will you please tell me a solution for the same.

If you don't want your application appear among the launchable applications with an icon just edit your AndroidManifest.xml
and remove the following:
<category android:name="android.intent.category.LAUNCHER" />
The following line will tell android to show the app in the launcher.

Here is the Working code Snippt :
ComponentName componentToDisable = new ComponentName(
getApplicationContext().getPackageName(), Constant.main_package_name
+ ".Splash"); // .Splash Launcher Activity
getPackageManager().setComponentEnabledSetting(
componentToDisable,
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
finishActivities(); // Finish All activity

Android how to programmatically hide launcher icon

my app is designed to only need to be run once. As such I want to hide the icon from the launcher after the first run, but without uninstalling the app.
I have seen similar applications - they can remove their own icons from the launcher app list. How can I achieve the same results? Thank you.

PackageManager p = getPackageManager();
p.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
Note that the icon may not be gone until the next reboot.

Hide app's icon using below code
PackageManager pkg=this.getPackageManager();
pkg.setComponentEnabledSetting(new ComponentName(this,SplashActivity.class),PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
// activity which is first time open in manifiest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
Here is how to bring back the app's icon
PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this,SplashActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

With Android Q (API 29) Google changed the Launcher icon visibility behaviour. Even if you disable your Launcher Activity or completely remove the
android.intent.category.LAUNCHER <intent-filter> from all your Activities, the app will appear in the launcher and open the Android OS app settings, with the exception of:
Packages that don't declare any permissions in their respective manifest files
System apps
Apps that don't contain any components inside their
respective manifest's tag

You can have an app without a launcher by NOT including an intent filter with MAIN and LAUNCHER in the declaration of the Activity in the AndroidManifest - the question then becomes how to do the first kick off.. Widget maybe ?

Hide app icon using this code:
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);
and bring it back, with this:
PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
NOTE: This will not work for Android 10
