Android hide/unhide app icon programmatically

Hide app's icon using below 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);

Here is how to bring back the app's icon.

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 Edit:

According to docs, as of Android Q (API 29) all app icons will be visible in the launcher no matter what unless:

As of Android Q, at least one of the app's activities or synthesized
activities appears in the returned list unless the app satisfies at
least one of the following conditions:

• The app is a system app.
• The app doesn't request any permissions.
• The tag in the app's manifest doesn't contain any child elements that represent app components.

Additionally, the system hides synthesized activities for some or all
apps in the following enterprise-related cases:

• If the device is a fully managed device, no synthesized activities for any app appear in the returned list.
• If the current user has a work profile, no synthesized activities for the user's work apps appear in the returned list.

android hide app icon programmatically just works in my packagename

This means that i can hide my app icon only?

Correct. There may be some options for doing this as a device owner app, but ordinary apps cannot disable other apps.

How to hide/unhide an application from Launcher when the application uses a permission?

I'm not sure if "officially not supported" is an answer or not. But unfortunately, according to docs:

As of Android Q, at least one of the app's activities or synthesized
activities appears in the returned list unless the app satisfies at
least one of the following conditions:

• The app is a system app.
• The app doesn't request any permissions.
• The tag in the app's manifest doesn't contain any child elements that represent app components.
