[Android] Shader Error

[DansDesigns]

Hey all! Loving Empty-Epsilon! I'm getting multiple Shader errors, it may be that the Android tablet I am using is not able to run EE..

Cube U30GT Android 4.1.1

able to install both armeabi-v7a and arm64-v8a apks but when running either version of the game I get the following errors: 1:19:L0001: Expected token ';', found 'uniform' (appears twice) 1:20:L0001: Expected token ';', found 'uniform' 1:31:L0001: Expected token ';', found 'uniform' (appears twice) 1:27:L0001: Expected token ';' found 'const'

clicking 'ok' on each error box brings up the next error, then after the last the game just shows a black screen.. anyone have any ideas?

thank you!

There was a missing ; in a conditional path that only happens on low-end devices. And looks like you are the first to do this low :)

How critical is it for you to have it working on this device? As in, how long can you wait for a release?

(if the shader fails to compile, then a black screen totally makes sense)

hey thanks for the reply, its not essential, just testing the lower limits really :)

I have a couple of Android 4.01 and 4.1.1 Tablets laying around and was hoping to find a use for them.. Is it possible to build EE for these lower version devices?

I imagine lots of people have older tablets and phones just sitting in draws, might be a good way to bring some life back into them?

My lowest device I had access to at the time I added android support was an Samsung S3, which has android 4.4

I would not be surprised if lower versions are possible. But there are a bunch of things to this:

• How much effort are you willing to put into this, building for android requires quite a bit of setup, but is explained at https://github.com/daid/EmptyEpsilon/wiki/Build-%E2%80%90-Android (you do need a linux system to build on)
• Depending on the device, you might have an ARMv5 or MIPS device, which requires an older SDK and a different ANDROID_ABI setting. And might need an older SDL2 version as well.
• OpenGL ES 2.0 is required, some older devices might only support OpenGL ES 1.x, which would require rewriting most of the rendering code, not really feasible.
• After all this builds, it might not run, and you'll need to debug on the device or check the android logs with logcat.

Ahh i see, thank you that's alot of good bits of information!

After some digging the specs of the tablets that failed to run: Cube U30GT - Android 4.1.1 - RK3066 CPU with Mali 400 - OpenGL ES 2.0, OpenGL 1.1 GoClever A972BK - Android 4.0.4 - Allwinner A10 Mali 400 - OpenGL ES 2.0, OpenGL 1.1 - (wont install - prob due to being a sun4i based cpu)

Ok, so in theory they could work, but do require custom builds.

Ah ok, good to know.. I may try and build for them at somepoint, have a linux pc but not built for android before, most of my experience is with Arduino and esp32s 😄

On a related note. Where are the script files n such located on android? I couldn't see any folders related to EE in sdcard/Android/..

[daid]

On android everything is packed into the app assets

haha ok, that would be why i couldnt find any script files!
