• Compute SHA-256: use MessageDigest on file InputStream.
• PackageInstaller.Session: use PackageInstaller.createSession, openWrite, write, fsync, commit with IntentSender for status.
• FileProvider: configure provider in Manifest and create content Uri via FileProvider.getUriForFile(context, authority, file) for ACTION_VIEW installs.
• Permission flows:
  • REQUEST_INSTALL_PACKAGES runtime permission check and manifest declaration.
  • For Android 8+: Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES with Uri.fromParts("package", context.getPackageName(), null).
• Broadcast receiver: listen for PackageInstaller.ACTION_SESSION_COMMITTED or monitor PACKAGE_ADDED/PACKAGE_REPLACED.
