Dolphin Android Running on Switch cannot use OpenGL

[devdawg]

Hey guys! I've been using Dolphin on PC for a while, and I found out that Android was ported to Switch by the SwitchRoot team. I immediately installed Dolphin, and I was delighted to see that I could at least run games on Vulkan (albeit the lesser performance). I tried OpenGL, but I get the message

Code:

GPU: OGL ERROR: Need OpenGL version 3.
Does your video card support OpenGL 3?

Which is then followed subsequently by:

Code:

Failed to initialize video backend!

I'm on the latest dev build, and also OpenGL works in Yaba Sanshiro (a Saturn emulator) so I'm not too sure what's going on. Is this an issue with the Android ROM, or OpenGL compatibility with Dolphin and the system?

Finally, thanks so much for even making it possible for the games to run, most times at full speed. I really do appreciate the developers' hard work, and it definitely doesn't go unnoticed!

Any help is appreciated, thanks in advance

First of all run some API viewer tools like opengl extensions viewer or vulkan viewer to see what API your Android build supports.
APK here https://apkpure.com/opengl-es-capsviewer/de.saschawillems.glescapsviewer https://apkpure.com/hardware-capsviewer-for-vulkan/de.saschawillems.vulkancapsviewer and then You can even upload a report.

Apis used on Android is mainly Opengl ES. Your error detection says about Opengl.

Hello! I checked yesterday, and the application said that up to OpenGL-ES 3.2 was available.

We're pretty sure this is a bug that the maintainer of the LineageOS port for the Switch caused. Take it up with them.
