ARCore : should I add "uses-feature android:glEsVersion="0x00020000""?

In the ARCore demo app Preview 2, I don't see the following line in the manifest:

<uses-feature android:glEsVersion="0x00020000" android:required="true" />

Whereas it is required in the openGL tutorial here :

https://developer.android.com/training/graphics/opengl/environment.html

So, should I include it or not ?

By the way, is is written in the openGL tutorial :

If your application uses texture compression, you must also declare which compression formats your app supports, so that it is only installed on compatible devices.

<supports-gl-texture android:name="GL_OES_compressed_ETC1_RGB8_texture" />
<supports-gl-texture android:name="GL_OES_compressed_paletted_texture" />

I don't know what "If your application uses texture compression" means (beginner in openGL). How do I know if my app uses compression? Should I include these 2 lines in my manifest ?

Thanks

Solution

  • If you want to use OpenGL ES in your app you should specify so in the manifest, same goes for texture compression, if you're compressing your textures and uploading them using glCompressedTexImage2D you're using texture compression...
