img src = cdvphotolibrary://... err_unknown_url_scheme && android sdk > 30

My Solution:

Modify PhotoLibrary.java :

start :
package com.terikon.cordova.photolibrary;

import androidx.annotation.Nullable;
import androidx.annotation.NonNull;
import android.webkit.WebResourceResponse;
import androidx.webkit.WebViewAssetLoader;
import android.util.Log;
import java.io.File;

end:
private static JSONObject createGetLibraryResult(ArrayList library, int chunkNum, boolean isLastChunk) throws JSONException {
JSONObject result = new JSONObject();
result.put("chunkNum", chunkNum);
result.put("isLastChunk", isLastChunk);
result.put("library", new JSONArray(library));
return result;
}

@OverRide
public CordovaPluginPathHandler getPathHandler() {
return new CordovaPluginPathHandler(new WebViewAssetLoader.PathHandler() {
@nullable
@OverRide
public WebResourceResponse handle(@nonnull String path) {
Log.d(TAG, "Path Handler " + path);
//e.g. cdvphotolibrary/thumbnail/photoId=3112&width=512&height=384&quality=0.8
if(path.startsWith(PHOTO_LIBRARY_PROTOCOL)) {
path = path.replaceAll("^cdvphotolibrary/", "cdvphotolibrary://");
path = path.replaceAll("thumbnail/", "thumbnail?");
path = path.replaceAll("photo/", "photo?");
Uri uri = Uri.parse(path);
Log.d(TAG, "URI " + uri);
Uri remappedUri = remapUri(uri);
Log.d(TAG, "RemappedUri " + uri);
if(remappedUri != null) {
try {
CordovaResourceApi.OpenForReadResult result = handleOpenForRead(remappedUri);
Log.d(TAG, "Result " + result.inputStream.available());
return new WebResourceResponse(result.mimeType, "utf-8", result.inputStream);
} catch (IOException e) {
LOG.e(TAG, "error open cdvphotolibrary resource "+ e);
}
}
}

    if(path.startsWith("__file__/")) {
      File file = new File(path.replaceAll("^__file__/", "/"));
      Uri fileUri = Uri.fromFile(file);
      Log.d(TAG, "fileUri " + fileUri);
      String mimeType = webView.getResourceApi().getMimeType(fileUri);
      Log.d(TAG, "mimeType " + mimeType);
      try {
        InputStream is = getContext().getContentResolver().openInputStream(fileUri);
        Log.d(TAG, "Result " + is.available());
        return new WebResourceResponse(mimeType, "utf-8", is);
      } catch(Exception e) {
        LOG.e(TAG, "error open file resource "+ e);
      }
    }
    return null;
  }
});

}

}

and modify javascript code:

    cordova.plugins.photoLibrary.getThumbnailURL(
        row.libraryItem_id, //libraryItem or libraryItem.id
        function (thumbnailURL) {
            thumbnailURL = thumbnailURL.replace("cdvphotolibrary://", "/cdvphotolibrary/").replace("thumbnail?", "thumbnail/");
            $("img[name='" + ID + "']").attr('src', thumbnailURL);
        },
        function (err) {
            console.log("ERROR: openPhoto, " + err);
        }
    );
