Android Studio: PackageManager package not found | How to access packages on Android 11?

Question

I am trying to run this sample code from TutorialPoint but it is always showing toast

Intent launch = getPackageManager().getLaunchIntentForPackage("com.google.android.youtube");
    if (launch != null) {
        startActivity(launch);
    } else {
        Toast.makeText(P01.this,
                "There is an issue running this code!",
                Toast.LENGTH_SHORT).show();
    }

Can someone please help with how to rectify it!

After requesting help over here, I searched for something relevant on Stack Overflow and came across this post. I used it to display all packages on my device, but instead, it only listed a handful:

ResolveInfo{f1539ce com.android.settings/.Settings m=0x108000}
ResolveInfo{6fa90ef com.android.vending/.AssetBrowserActivity m=0x108000}
ResolveInfo{8b2b7fc com.android.stk/.mtk.StkLauncherActivityII m=0x108000}
ResolveInfo{10f4e85 com.dsaghicha.uscs407practicals/.MainActivity m=0x108000}

The last one being my app's package. If I run the above code on any one of these packages it will run

Apparently, I am using Android 11 and there is a privacy policy that restricts package visibility on Android 11. Read more Now, how to access the package on Android 11?

Intent intent = new Intent(Intent.ACTION_VIEW); intent.setData(Uri.parse("https://www.youtube.com/")); intent.setPackage("com.google.android.youtube"); PackageManager manager = getPackageManager(); List info = manager.queryIntentActivities(intent, 0); if (info.size() > 0) { startActivity(intent); } else { //No Application can handle your intent } — JackHuynh, Apr 11 '21 at 02:38
@JackHuynh it didn't work. It straight went to the else block. I also got a warning: `Consider adding a declaration to your manifest when calling this method ` — Darshaan Aghicha, Apr 11 '21 at 11:12

In Android 11, a new Privacy Policy Update restricts package visibility to your android app.

So, you have to explicitly request access to the package by declaring it in the AndroidManifest.xml

<queries>
    <package android:name="com.google.android.youtube"/>
</queries>

Adding this piece of code to AndroidManifest.xml resolved the issue in my case.
