SkQP
====
**Motivation**: Test an Android device's GPU and OpenGLES & Vulkan drivers with
Skia and Skia's existing unit & rendering tests.
How To Use SkQP on your Android device:
1. To build SkQP you need to install the
[Android NDK](https://developer.android.com/ndk/).
2. [Checkout depot\_tools and Skia](https://skia.org/user/download),
then go to Skia's source directory:
export PATH="${DEPOT_TOOLS_PATH}:$PATH"
cd $SKIA_SOURCE_DIRECTORY
3. Configure and build Skia for your device's architecture:
arch='arm64' # Also valid: 'arm', 'x68', 'x64'
android_ndk="${HOME}/android-ndk" # Or wherever you installed the NDK.
mkdir -p out/${arch}-rel
cat > out/${arch}-rel/args.gn << EOF
ndk = "$android_ndk"
ndk_api = 26
target_cpu = "$arch"
skia_embed_resources = true
is_debug = false
EOF
tools/git-sync-deps
bin/gn gen out/${arch}-rel
ninja -C out/${arch}-rel skqp_lib
4. Download meta.json from [https://goo.gl/jBw3Dd](https://goo.gl/jBw3Dd) .
This is the data used to build the validation model.
5. Generate the validation model data:
go get -u go.skia.org/infra/golden/go/search
go run tools/skqp/make_gmkb.go ~/Downloads/meta.json \
platform_tools/android/apps/skqp/src/main/assets/gmkb
Run as an executable
--------------------
1. Build the SkQP program, load files on the device, and run skqp:
ninja -C out/${arch}-rel skqp
adb shell "cd /data/local/tmp; rm -rf skqp_assets report"
adb push platform_tools/android/apps/skqp/src/main/assets \
/data/local/tmp/skqp_assets
adb push out/${arch}-rel/skqp /data/local/tmp/
adb shell "cd /data/local/tmp; ./skqp skqp_assets report"
2. Get the error report if there are errors:
adb pull /data/local/tmp/report /tmp/
tools/skqp/sysopen.py /tmp/report/report.html
Run as an APK
-------------
0. Install the [Android SDK](https://developer.android.com/studio/#command-tools).
mkdir ~/android-sdk
( cd ~/android-sdk; unzip ~/Downloads/sdk-tools-*.zip )
yes | ~/android-sdk/tools/bin/sdkmanager --licenses
export ANDROID_HOME=~/android-sdk
1. Build the skqp.apk, load it on the device, and run the tests
platform_tools/android/bin/android_build_app -C out/${arch}-rel skqp
adb install -r out/${arch}-rel/skqp.apk
adb logcat -c
adb shell am instrument -w \
org.skia.skqp/android.support.test.runner.AndroidJUnitRunner
2. Find out where the report went (and look for Skia errors):
adb logcat -d org.skia.skqp skia "*:S"
3. Retrieve and view the report if there are any errors:
adb pull /storage/emulated/0/Android/data/org.skia.skqp/files/output /tmp/
tools/skqp/sysopen.py /tmp/output/skqp_report/report.html
