Programs that can run on Android 12 and below are now running on Android 13 systems. When installing, it prompts: The application could not be installed: INSTALL_PARSE_FAILED_MANIFEST_MALFORMED.
solution:
You need to add android:exported to AndroidManifest.xml, android:exported is only required by Android 13, so add an android:exported="true" to both the activity node and the receiver node under the application node, and then recompile and run.
