I'm very happy to release B4A v5.00.



With this version we are moving to the next generation of B4X IDE. Almost all of the IDE components, both back-end and front-end components, were rewritten.

The new IDE is significantly more powerful, smarter, more modern and more scalable.
There are too many improvements to list them all.
Note that this version is fully backwards compatible with previous versions.

Some of less obvious new features:

- Press on Ctrl + Click to jump to an identifier (sub, variables, etc.).
- Themes - Ctrl + T
- Sophisticated conditional compilation: #If, #Else If, #Else and support for OR and AND. Also supported in the manifest editor and designer scripts.
- Dockable layout. Including support for multiple open editors.
- Find all references - F7.
- Quick search - Ctrl + F.
- Goto sub / module - Ctrl + E.
- Smarter autocomplete.
- Hover over variables and expressions in debug mode.
- Structure matching.
- Automatic warnings and errors highlighting.
- Support for multiple visual designer windows
- Better support for selection and editing of multiple controls.
- Views tree supports drag and drop to allow changing the z-order.
- Integrated abstract designer with support for zooming.
- Memory leak related to layout animations was fixed.
- StartServiceAtExact keyword.

The following features are currently not implemented (they might be added in the future):
- B4A-Bridge over Bluetooth.
- Bookmarks (not to confuse with breakpoints).


- Microsoft .Net Framework 4.0+ is required. If you are running Windows XP then you should install .Net Framework 4.0: https://www.microsoft.com/en-us/download/details.aspx?id=17851

- Developers running Vista or above should install .Net Framework 4.5.2: https://www.microsoft.com/en-us/download/details.aspx?id=42642

Developers who are eligible for a free upgrade should receive an email with installation instructions.
Other developers will receive a discount offer. Please allow up to 24 hours for the mails to arrive.
I want to thank the beta testers for their help with this major release.

in B4A Version 5.0 ... in the Abstract Designer it is possible (for example) to set a button via right-mouse-click "Send To Back".
But if once a button is "Send To Back", there is no way to get it again via right-mouse-click "Bring To Front".

In Version 4.3 there was a menu in the Views Tree, but in Version 5.0 there is none ... or is there another solution? o_O

You can change the order of the views by using drag and drop in the Tree View.

Why do these new installers take ages to pop up?
