Hi Jan,

Seems its nothing to do with file plugin, By looking into the log seems plugin "Cordova-plugin-compat"  version is not compatible with Android Cordova. Please check below plugin version.

Please read the plugin details using below url.

https://www.npmjs.com/package/cordova-plugin-compat

Hi Jan,

you could try to make use of the latest version of the cordova-file-plugin available on Github, namely version 6.0.2. In order to do it, open the FilePlugin module in Service Studio and change the Extensibility Configuration of the module to the following:

{

    "plugin": {

        "url": "https://github.com/apache/cordova-plugin-file.git#6.0.2"

    }

}

Generate again the Android distribution of the application. You should not find any problem.

Best regards, 

pedro
