Cannot use Android Layout editor with widgets

[kenargo]

The sample itself cannot show the widgets (see below output in Android Studio) and this makes it very difficult to design UI using the widgets.

The following classes could not be instantiated: - dji.ui.widget.FPVOverlayWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.config.CameraConfigWBWidget (Open Class, Show Exception, Clear Cache) - dji.ui.panel.PreFlightCheckListPanel (Open Class, Show Exception, Clear Cache) - dji.ui.widget.VideoSignalWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.TakeOffWidget (Open Class, Show Exception, Clear Cache) - dji.ui.panel.CameraSettingAdvancedPanel (Open Class, Show Exception, Clear Cache) - dji.ui.widget.config.CameraConfigISOWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.FocusModeWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.AutoExposureLockWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.config.CameraConfigEVWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.PreFlightStatusWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.CameraConfigStorageWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.RemoteControlSignalWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.controls.CameraControlsWidget (Open Class, Show Exception, Clear Cache) - dji.ui.panel.CameraSettingExposurePanel (Open Class, Show Exception, Clear Cache) - dji.ui.widget.config.CameraConfigApertureWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.FPVWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.GPSSignalWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.FocusExposureSwitchWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.VisionWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.BatteryWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.ReturnHomeWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.RemainingFlightTimeWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.dashboard.DashboardWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.FlightModeWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.WiFiSignalWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.config.CameraConfigShutterWidget (Open Class, Show Exception, Clear Cache) - dji.ui.widget.ConnectionWidget (Open Class, Show Exception, Clear Cache) Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE. If this is an unexpected error you can also try to build the project, then manually refresh the layout.

@kenargo Please check 4.4.1 and see if the issue still exists. Thanks!

waht's the problem? why "Caused by: android.view.InflateException: Binary XML file line #28: Error inflating class dji.ux.widget.FPVWidget" I'm crazy now!!

[kenargo]

It's a know issue.  The widgets access code at design time which results in the widgets throwing an exception and them the designer just shows a blank box in their place.

I haven't heard of any estimated fix time and I suspect now that DJI plans to release the wishes as open source the fix likely will come from the community after the release.   Just guessing.

ok thanks for reply

I'm guessing DJI developer can't solve the problem or you must pay for it , anyhow , I just expect they can solve the problem quickly.

I am also struggling with this issue. Hard to use the UX elements and position them correctly if they can't be previewed. Are there any updates on this issue?

[Chickinnick]

The issue is present in 4.11.1 Using androidx

[mayurpatil307]
