B4XGoods-B4X好物整理，每周六更新

I wanted an easy way to create simple B4A notification icons consisting of a letter and a symbol; the symbol could then show things like ''there is a message'' / ''there are no messages'' / ''there is no network connection''. So I came up with MakeNotificationPng. Attached you''ll find the B4J project as well as a small B4A app (TestNotificationPng) with which you can test the generated icons.

B4ATutorialJSON

Convert collections to json and vice versa

There is a new JSON type which is used to convert maps or lists to json strings and vice versa, using the new As keyword. The idea is that you have a collection or string, you direct the compiler to treat it as "JSON" and then convert it to a string or a collection.

My way to work with local DB

I save the SQLite DB used by my apps in the directory corresponding to File.DirInternal, which is the app''s exclusive space. This, however, prevents you from accessing the DB from outside (directly from Windows explorer) and checking the changes made by the app. It would be possible to get that DB if it were in rp.GetSafeDirDefaultExternal (rp = RuntimePermissions).

B4ATutorialPermissions

Runtime Permissions (Android 6.0+ Permissions)

The nice thing about runtime permissions is that the user is not asked for any permission when they install your application from Google Play. Instead they will be asked to approve "dangerous" permissions at runtime.

Create Custom Keyboard Layout for Coding

Sometimes it is really annoying to have keys we use so often to be lying in most inaccessible parts of keyboard. And to make the matter worse they might also involve combination of shift etc. You can create a custom keyboard layout which you can switch to easily in Windows 10/11 on need basis.
