I am trying to create a widget preview with the WidgetPreview app on a API 26 emulator, but it shows "Error saving preview" as a toast message. It works on API level 21. There are zero results online. Anyone have an idea what could cause this?
If the emulator fails to launch due to the error vulkan-1. dll cannot be found , you probably need to update the emulator. To update the emulator in Android Studio, go to Tools > SDK Manager and install the latest stable version of Android platform.
The reason why the designs look different is that the emulator's screen configuration is different to that which is used to render the design preview.
I solved my problem by granting the Storage Permission manually for the Widget Preview app in the app settings. The default Widget Preview app on the emulator crashes when trying to send a mail, but there is a newer version on the Playstore that works.
