Signature spoofing patch doesn't work for Android 7.1.1 #245

Hi,

I want to build a custom ROM based on Android 7.1.1... Applying the signature spoofing patch from here (https://github.com/microg/android_packages_apps_GmsCore/tree/master/patches) worked fine for Android 6 and 7.0, however for 7.1.1 I receive the following error:

Prüfe Patch core/res/AndroidManifest.xml ...

    return PackageParser.generatePackageInfo(p, gids, flags,
            ps.firstInstallTime, ps.lastUpdateTime, permissions, state, userId);
}

@Override

error: Anwendung des Patches fehlgeschlagen: services/core/java/com/android/server/pm/PackageManagerService.java:2816
error: services/core/java/com/android/server/pm/PackageManagerService.java: Patch konnte nicht angewendet werden

Can you give me a hint how to fix this?
Thanks in advance and best regards.
