I downloaded the zip file from that site (the link is at the top right), then extracted the two files in the folder (src/android/libs) and placed them in the project's libs directory. Then, I refreshed the project.
As the error kept going, he told me to "Make sure you removed sqlite-native-driver.jar". I deleted that file from the libs directory, refreshed the project, and The following error.
I've been using an old version of "Cordova-SQLitePlugin" from "brodysoft" github account. Now I wanted to update my plugins and it was slightly confusing to try figure out where the plugin I had used had gone and is the litehelpers plugin the same one as the brodysoft one was.
I even found a github issue litehelpers/Cordova-sqlite-storage#95 discussing this.
Even though https://github.com/brodysoft/Cordova-SQLitePlugin redirects to https://github.com/litehelpers/Cordova-sqlite-storage it would be nice if the Cordova-sqlite-storage readme mentioned all the old repositories which have been deprecated, so that it would be more clear/explicit what the history of the plugin actually is.
I assume litehelpers/Cordova-sqlite-storage is a newer version of brodysoft/Cordova-SQLitePlugin? Even though I've been using version 1.0.3 of Cordova-SQLitePlugin and Cordova-sqlite-storage seems to be now v0.7.11.
