Updating project file

Build Script in API-Samples are generated during upstream repo syncing up process. If for some reason (like using different stlport) you like to generate scripts yourself, the procedure described here might be helpful.

1. Follow instruction in upstream to install all required tools such as:

• cmake
• compiler (gcc)
• python
• others

2. Build shaderc in NDK. In a command-prompt navigate to “${ndk_root}/sources/third_party/shaderc” and run the following command

../../../ndk-build NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=Android.mk APP_STL:=gnustl_static APP_ABI=[armeabi-v7a|arm64-v8a|x86|x86_64|all] libshaderc_combined -j16

APP_STL can be:

• gnustl_static
• gnustl_shared
• c++_static
• c++_shared

Samples by default choose gnustl_static, so shaderc needs to be built with gnustl_static too. When you want to use different stlport in the sample, shaderc should be be built with the same stlport flavor.

3. Sync external project and generate files. In a command-prompt navigate to repo root, run the following commands

./update_external_sources.sh -s -g

This process is required to build Hologram and demo sample.

4. Build Android Studio project file

• Change project template files
• Re-generate API-Sample project files with

cmake -DANDROID=ON -DANDROID_ABI=[armeabi-v7a|arm64-v8a|x86|x86_64|all(default)]

5. Import "API Sample" project into Android Studio by choosing “Import project (Eclipse, ADT, Gradle)” and select build.gradle locating at the root of local your repo directory.
