I am trying to login Facebook with Firebase. I have installed all the libraries required and completed the required configuration. Still, whenever I try to start my app it is giving me this error:

Answer 1

Able to solve this with below changes :

Just go to the below file in Ionic

plugins/cordova-universal-links-plugin/hooks/lib/android/manifestWriter.js

I fixed issue by changing pathToManifest as below:

var pathToManifest = path.join(cordovaContext.opts.projectRoot, 'platforms', 'android', 'cordovaLib', 'AndroidManifest.xml');

to

var pathToManifest = path.join( cordovaContext.opts.projectRoot, 'platforms', 'android', 'app', 'src', 'main', 'AndroidManifest.xml');

For anyone that's looking into this these days, the actual fix for this was published by someone which you can pull in as a cordova plugin https://github.com/nordnet/cordova-universal-links-plugin/issues/133#issuecomment-369260863

@okaufmann you can use the changed version of the plugin. since it's not merged in the nordnet repository, you must remove the plugin and install again using: cordova plugin add https://github.com/walteram/cordova-universal-links-plugin

After doing...

cordova plugin rm cordova-universal-links-plugin
cordova plugin add https://github.com/walteram/cordova-universal-links-plugin

.. my project was able to build successfully.
