Having spelunked through some Google announcements on this, it looks like they planned to do so back when Android 11 was in development (https://android-developers.googleblog.com/2020/02/Android-11... ), but I can’t find any evidence that image decoders are included in the current Android Mainline system updates that ship via Google Play - video codecs are, but not image ones apparently.
It looks as if they planned to include image decoders, but that was dropped sometime during the Android 11 development cycle, unless I’ve missed something (which is certainly possible).
The image decoders are in android.graphics (https://developer.android.com/reference/android/graphics/pac... ) & that API subset is not listed in the Android Mainline system modules that are catalogued here: https://source.android.com/docs/core/ota/modular-system
It looks as if they planned to include image decoders, but that was dropped sometime during the Android 11 development cycle, unless I’ve missed something (which is certainly possible).
Edit: the final dev release announcement for Android 11 keeps the same paragraph about the native image decoder. So maybe it is there & I’m just not finding it? https://android-developers.googleblog.com/2020/09/android11-...
