Could not retrieve info for package %s with flags 0x%X for u

Error message

Could not retrieve info for package %s with flags 0x%X for user %d

What it means

PackageManagerCompat.getPackageInfo retries getPackageInfoInternal with major component flags (activities, services, providers, receivers, permissions) stripped. If it still returns null, the package info genuinely cannot be retrieved, so it throws PackageManager.NameNotFoundException with a formatted message including package name, stripped flags, and userId. This means the failure is not flag-related — the package is unavailable for that user.

Solutions

1. Catch PackageManager.NameNotFoundException and treat it as 'package unavailable for user'.
2. Verify the package exists via getInstalledPackages/listing before querying with component flags.
3. Check the correct userId (0 vs profile).
4. Retry after a short delay if a concurrent install/update may be in progress.

Example fix

// before
PackageInfo pi = PackageManagerCompat.getPackageInfo(pm, pkg, flags, userId);
// after
PackageInfo pi;
try {
    pi = PackageManagerCompat.getPackageInfo(pm, pkg, flags, userId);
} catch (PackageManager.NameNotFoundException e) {
    Log.w(TAG, "Package unavailable: " + pkg);
    pi = null;
}

boolean exists;
try { pm.getPackageInfoAsUser(pkg, 0, userId); exists = true; }
catch (PackageManager.NameNotFoundException e) { exists = false; }

try {
    PackageInfo pi = PackageManagerCompat.getPackageInfo(pm, pkg, flags, userId);
} catch (PackageManager.NameNotFoundException e) {
    // treat as unavailable for user
}

When it happens

Trigger: Calling getPackageInfo(pm, packageName, flags, userId) for a package that does not exist, is being uninstalled, or is hidden/disabled for the given user, even after retry without component flags.

Common situations: Race with an app updating/uninstalling; querying a package not visible on a managed profile; package name typo; querying hidden (suspend/hidden) packages without proper permissions.

Background: "Not found" and "does not exist" errors: why "Task not found", "No such folder", and "Can't find" fire when a lookup comes back empty — this error's family across 14 libraries.
