How to edit to add functionalities, and update the packages for changes in package

[mghatiya]

Hi,

I am bit limited in my coding knowledge and abilities, so please excuse silly question and it would be great if you could make your answer to be such that a dummy can understand.

I have built apps using Bubblewrap. But now I am getting some errors in play store console which I do not understand what they are for. I thought I'd update the bubblewrap in case there have been any updates.

Questions:

1. How do I update? I saw the readme file and got bit scared in the Update section where it says that we should not use any external editor to edit the files. How else will I edit the project and functionalities? I did it in Android studio for some small functionalities like push notifications handling.

Here's what I am talking about.

2. Now if I update will it overwrite all the changes I have made? How to know which files will be changed, which won't be?

3. This is an example of crash that my users are having.

com.google.androidbrowserhelper.trusted.TwaLauncher$TwaCustomTabsServiceConnection.onCustomTabsServiceConnected

Could you suggest what could be causing this?
