I'm happy to release B4A v5.80. This update includes important new features, including better support for custom views: Improvements: Custom views: [B4X] Custom Views with Enhanced Designer Support With this feature it is much easier to add and configure custom views. #ExcludeClasses: https://www.b4x.com/android/forum/threads/new-feature-three-birds-with-one-stone.63127/ This attribute makes it simple to exclude classes not required from libraries such as google play services. CreateResource manifest editor keyword: https://www.b4x.com/android/forum/threads/new-feature-three-birds-with-one-stone.63127/#post-398974 Allows creating XML resource files from the manifest editor. For example with this code we can use the native light theme based on the Android version: Code: SetApplicationAttribute(android:theme, "@style/LightTheme")CreateResource(values-v20, theme.xml,<resources> <style name="LightTheme" parent="@android:style/Theme.Material.Light"> </style></resources>)CreateResource(values-v14, theme.xml,<resources> <style name="LightTheme" parent="@android:style/Theme.Holo.Light"> </style></resources>) Debugger improvements and fixes. Mostly related to larger projects. Coarse location permission added to BluetoothAdmin. Required for discovery in Android 6. The default setting of the holo theme in the manifest editor was removed. It is recommended to use a custom theme or the device default theme. The compiler will issue a warning about explicit usage of the holo.theme. The WYSIWYG designer defaults to material theme on Android 5+. The READ_LOGS permission was removed from LogCat object. It is not useful since Android 4.1. The compiler will issue a warning if the targetSdkVersion is missing or if the value is not between 14 to 22. ViewsEx library - Includes two views implemented as custom views (Switch and RatingBar). The source code of this library is available in the custom views tutorial. View.Parent - Returns the view's parent. OkHttp and OkHttpUtils2 libraries are included. Other minor IDE improvements and bug fixes. Developers who are eligible for a free upgrade will receive an email with upgrade instructions.
