I'm trying to modify an app's XML files (GBoard doesn't have enough obscure unicode characters), but it keeps giving the aforementioned error when loading the resource.
My module's source is this:
public class GBoard implements IXposedHookZygoteInit, IXposedHookInitPackageResources {
private static String MODULE_PATH;
@Override public void initZygote(StartupParam startupParam) throws Throwable {
MODULE_PATH = startupParam.modulePath;
}
@Override public void handleInitPackageResources(XC_InitPackageResources.InitPackageResourcesParam resparam) {
if (!resparam.packageName.equals("com.google.android.inputmethod.latin"))
return;
int id = resparam.res.getIdentifier("softkeys_input_en", "xml", "com.google.android.inputmethod.latin");
XposedBridge.log(resparam.packageName + " " + id + " " + resparam.res.getXml(id));
XModuleResources modRes = XModuleResources.createInstance(MODULE_PATH, resparam.res);
Class c = modRes.getClass();
while(c != Object.class && c != null) {
XposedBridge.log(c + "");
for(Object f : c.getDeclaredFields())
XposedBridge.log(" " + f);
c = c.getSuperclass();
}
resparam.res.setReplacement(id, modRes.fwd(R.xml.softkeys_input_en));
XposedBridge.log(resparam.packageName + " " + id + " " + resparam.res.getXml(id));
}
}(I added some logs to confirm that mCachedXmlBlockIds indeed doesn't exist)
The log output is this:

As you can see, the resource loads just fine before being overridden, the field does indeed not exist, and it throws an error when trying to load it after overriding. The keyboard itself seems to be unaffected.
My guess is that there's some sort of API conflict between the versions of Xposed and Android I use, but I have no proof for this. Xposed version is 90-beta3, compiled for SDK 27, device TA-1004 (HMD Global), Android version 8.1.0 (SDK 27), ROM is 00WW_4_88C (vanilla, though not the latest update).
As a side note, is it possible to refer to other XML files and ids from my modified files? AAPT reasonably complains about them not existing when I try.
