B4JLibraryJSON

JSON Formatter and validator

I am working on an app that needs to be able to manipulate JSON strings. They are stored in a compact format then prettified for display and editing. The main problem I have found is that if the json is invalid, it can''t be prettified with the existing JSON lib. I found this project on github and ported the format class to B4j.

jXmlSaxEnhanced

The current jXmlSax library lacks the character event as discussed here: https://www.b4x.com/android/forum/t...ements-and-text-are-mixed.121134/#post-757245 I modified the jXmlSax library to add the characters event and renamed it as jXmlSaxEnhanced.

B4JLibraryDesigner [DSE]

PaneLayout [DSE]

I''ve been working a lot in MySQL lately and got fed up creating layouts that were very similar to show audit reports. I came up with this which is a designer script extension that loads however many labels you specify into a pane. You can define the widths, left margin and EventNames for the labels so they can respond to being clicked.

B4JLibraryFirebase [SERVER]

FirebaseServer - backend verification for signed in users [server]

Users can sign in to your B4A or B4i apps using Google or Facebook with the FirebaseAuth libraries. FirebaseServer completes the puzzle with server side verification of the user. This means that the signed in user gets a token id (long string) from Firebase services by calling FirebaseAuth.GetUserTokenId. The client sends the token id to the server. The server verifies the token using this library. Once verified we know for sure that the request was sent from our app and we know the identity of the signed in user.
