# Running ndk-build will build libvpx and include it in your project.
#
+# Alternatively, building the examples and unit tests can be accomplished in the
+# following way:
+#
+# Create a standalone toolchain from the NDK:
+# https://developer.android.com/ndk/guides/standalone_toolchain.html
+#
+# For example - to test on arm64 devices with clang:
+# $NDK/build/tools/make_standalone_toolchain.py \
+# --arch arm64 --install-dir=/tmp/my-android-toolchain
+# export PATH=/tmp/my-android-toolchain/bin:$PATH
+# CROSS=aarch64-linux-android- CC=clang CXX=clang++ /path/to/libvpx/configure \
+# --target=arm64-android-gcc
+#
+# Push the resulting binaries to a device and run them:
+# adb push test_libvpx /data/tmp/test_libvpx
+# adb shell /data/tmp/test_libvpx --gtest_filter=\*Sixtap\*
+#
+# Make sure to push the test data as well and set LIBVPX_TEST_DATA
