glError 1280 on Android 4.2

[kiffa]

My game crashes on Android 4.2(test with only one device who has a heavily customized system based on Android 4.2), but runs well on other versions(2.3 - 4.4).

First, seems the engine can't find the default shader-files in jar, so I push all sharder-files into a zip named "jpct_shaders.zip", and put it in "assets" of project, then call

Code Select Expand


GLSLShader.setShaderLocator(new ShaderLocator(getAssets()));


When I run game again, the engine found shader-files, but crashed when gen VBO, logs:

Could be everything...most likely a driver problem of some kind. Try to set http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Config.html#internalMipmapCreation to true. It helped with a similar problem on some other device.

Setting "Config.internalMipmapCreation = true" resolve it, thanks.

I want to always set this option to true in order to support most devices, but I don't know if there is any disadvantages than GPUMipmapCreation(such as loading time、memory usage\peak、performance and so on).

Not really...rumors are that doing it on the cpu is slower, but i never really noticed that. I'll make this setting default in the next version anyway.
