* Lower limit from API 21 to API 19 This was requested by an internal application. API 19 is when OpenGL ES 3.0 support was added so there is no good reason for us to not support this API level. The only trick is to avoid referring to the glTexStorage2DMultisample symbol directly as it only exists in 3.1. * Compile out code we never use * Use reflection to handle shared EGL contexts pre-API 21. * Remove comment * More fixes required to run on API level 19 - dlym() fails for ashmem on API 19, so we only try on API 26+ instead. - Older emulation for OpenGL ES 3.0 returns error states for valid API calls so we need to clear the GL error bit before we create the GL driver. - Activity lifecycle changes since API 19 would cause animations to keep running and to reference destroyed objects. - EGLContext.getNativeHandle() is new in API 21, we need to use reflection on API 19. The new code path uses the class loading trick to avoid a bytecode verification error on API 19. * Filament now runs properly on API level 19 This commit adds a new api_level() API to libutils which can be used to query the platform's API level. On Android it works as expected, other platforms currently return 0.
Android material-builder Sample
The material-builder sample shows how to generate materials programatically on the device as
opposed to with the matc tool on the host machine. The cost is a binary size increase of your app
due to the relatively larger size of the filamat library.
The buildMaterial method inside MainActivity.kt uses a MaterialBuilder() instance to compile a
material package whose payload is sent to the engine where it is applied towards the Renderable.
Before building
The filamat static library is needed to fascilitate material building on the device. Compiling the
library is slower and thus it is not built by the default build.sh command. To build, add the -l
flag to the build.sh command:
./build.sh -i -p android release
Explanation of flags:
- The
-iflag installs the libraries toout/android-release/, so this sample can find them. - The
-pflag andandroidargument choose Android as the platform to build for.
