I'm happy to release B4A v9.0 BETA. Most of the steps in the compilation process were rewritten and compilation is now much faster. This update also includes many other important improvements.

  • Compilation performance (about 2 times faster for first compilation and up to 4 times faster on following compilations).
  • Bookmarks and breakpoints are listed in the modules tree:

  • Auto backup improvements:
    • Project is saved before backup, based on the auto save option.
    • Project name added to the backup file.
    • The project folder is configurable (AutoBackupFolder in the ini file).
  • Warning for unused parameters in private, non-event, subs.
  • Additional library folder can be configured with a B4X folder for cross platform libraries: https://www.b4x.com/android/forum/threads/b4x-additional-libraries-folder.103165/
  • #Event declarations appear in the autocomplete list.
  • Fix for a long standing issue that caused scope changes of global variables to not always be detected.
  • Workaround for Android issue (https://issuetracker.google.com/issues/113122354) that caused services to fail to start in some edge cases. This is based on the automatic foreground mode feature.
  • Copy to clipboard option in the permissions dialog.
  • Missing maven resources can be added to the internal or additional libraries folders.
  • com.google.auto.value-auto-value-annotations added as an internal library. This is a missing maven resource that required by Firebase libraries.
  • B4XCollections, B4XFormatter, B4XTable, XML2Map and XUI Views are internal libraries.
  • Foreground services permission is added automatically. Required when setting targetSdkVersion to 28.
  • CreateResourceFromFile(Macro, Core.NetworkClearText) - Required when setting targetSdkVersion to 28 when communicating with non-SSL servers.
  • Application.Icon works with adaptive icons.
  • FirebaseAdMob v1.53 - Fixes an issue related to targetSdkVersion 28.
  • Files are listed in the removal dialog.
  • OkHttpUtils2 v2.81 - Includes a call to Service.StopAutomaticForeground (related to the workaround discussed above).
  • Other bug fixes and minor improvements.

An email with upgrade instructions will be sent to developers who are eligible for free upgrades.

Wow, very fast!!
So, no time for a coffee anymore in between compiling. :oops:
Compiling generated Java code.    (0.06s)
Convert byte code - optimized dex.    (12.85s)
Packaging files.    (3.07s)

instead of around 128 secs before!:D:p:D:p:D

Thanks, Erel.

I'm having lots of this warning message: Unused variable 'ba' (warning #9).

For example, for this Sub:
Sub changeAlpha(Color As Int, newAlpha As Int) As Int
    Return Bit.Or(Bit.And(0x00FFFFFF, Color), Bit.ShiftLeft(newAlpha, 24))
End Sub
