Package ${packageName} not found.

Error message

Package ${packageName} not found.

What it means

PackageManagerCompat.getApplicationInfo calls the hidden IPackageManager.getApplicationInfo, which may return null instead of throwing. When the returned ApplicationInfo is null, this compat method throws PackageManager.NameNotFoundException("Package <name> not found.") to signal the package does not exist for that user.

Solutions

1. Wrap the call in try-catch for PackageManager.NameNotFoundException.
2. Verify installation first via getInstalledPackages for the target user.
3. Check packageName spelling and the userId argument.
4. Declare the package in <queries> for visibility if targeting API 30+.

Example fix

// before
ApplicationInfo ai = PackageManagerCompat.getApplicationInfo(pkg, 0, userId);
// after
ApplicationInfo ai = null;
try {
    ai = PackageManagerCompat.getApplicationInfo(pkg, 0, userId);
} catch (PackageManager.NameNotFoundException e) {
    // handle absence
}

boolean installed = getInstalledPackages(userId).stream()
        .anyMatch(p -> p.packageName.equals(packageName));

try {
    ApplicationInfo ai = PackageManagerCompat.getApplicationInfo(pkg, flags, userId);
} catch (PackageManager.NameNotFoundException e) {
    ApplicationInfo ai = null;
}

When it happens

Trigger: Calling getApplicationInfo(packageName, flags, userId) where the package is not installed for userId, or the binder call silently returns null (package hidden/removed).

Common situations: Querying apps on a different user profile; checking a package right after uninstall; missing package visibility (<queries> filtering) on Android 11+; querying system packages removed in newer OS builds.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
