@rankaiyx @licheedev could you confirm about this issue again, as I don't see any problem rendering the image in android

@amitsin6h
My phone is Android 10.
All http-images can be rendered on desktop-editon, but failed on Android.

Starting with Android 9 (API level 28), cleartext support is disabled by default
https://developer.android.com/training/articles/security-config.html#CleartextTrafficPermitted
https://developer.android.com/guide/topics/manifest/application-element#usesCleartextTraffic

Add android:usesCleartextTraffic="true" on <application/> tag can solve this problem.
