## Additional context

The issue names Android image saving in Weex 0.26.4.43 but provides no source file, test, reproduction steps, or environment details. Start by obtaining the missing minimal example and comparing the Android and iOS image-save entry points; done means Android saves the image without the reported error and the behavior has a regression check.
