In my first attempt I kept the multiple project-level dependencies in
each sample's `build.gradle` but that resulted in a gradle error
concerning multiple copies of the same SO file. To work around this
we now append to "srcDirs" to bring in Java dependencies rather than
using project-level dependencies.
The new APK contents are now much more reasonably sized:
libfilament-jni.so 981 KB
libgltfio-jni.so 817 KB
libfilament-utils-jni.so 96 KB
Previously this was:
libfilament-utils-jni.so 1.8 MB
libgltfio-jni.so 1.8 MB (unused)
libfilament-jni.so 1 MB (unused)
Fixes#2070
* Rewrite Maven publish tasks to support multiple flavors
* Don't build filamat with an unused CMake option
* Don't compiler debug in release mode
* ... for real
* Link to BUILDING.md
* Re-organize Android Gradle files
Clean up our Gradle files, share versioning, etc. and prepare for
publication to sonatype.
* Use androix annotations for desktop
* Add samples as subprojects to root Gradle
* Fix build script
* Don't break when samples aren't compiled
* Better organize the Android Studio project
* 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.
For now this uses gltfio in the ubershader configuration in order
to avoid the filamat dependency. Note that we have not yet done a size
analysis of the `gltfio_core` library.
New Kotlin-based sample app is forthcoming.
