Build XWalk Android Core with full debug support

. xwalk/build/android/envsetup.sh --target-arch=x86
xwalk_android_gyp -Dandroid_full_debug=1
ninja -C out/Debug xwalk_core_shell_apk

Install App

adb install -r out/Debug/apks/XWalkCoreShell.apk

Load URL with adb

adb shell am broadcast -a org.xwalk.core.xwview.shell.launch -e url <url>

Test

# Build and install test suite
ninja -C out/Debug xwalk_core_shell_apk xwalk_core_test_apk
adb install -r out/Debug/apks/XWalkCoreTest.apk

# Set up environment
export XWALK_OS_ANDROID=1
. xwalk/build/android/envsetup.sh --target-arch=x86 

# Run test
python build/android/test_runner.py instrumentation --release --test-apk=XWalkCoreTest -v --num_retries=0 --test_data xwalkview:xwalk/test/data/device_files/

Debug Native Code with "adb_gdb*"

  • On Device, launch the App
  • On Host machine, to debug the browser process, use:
adb_gdb_xwalk_core_shell --verbose
  • [Deprecated] To debug the renderer process, use:
adb_gdb_xwalk_core_shell --verbose --sandboxed=[0-6]
  • If you want to debug the startup process
#Edit a file named 'xwview-shell-command-line' with content:
Xwalk --wait-for-debugger
#Then push it to device
adb push xwview-shell-command-line /data/local/tmp/xwview-shell-command-line
#Then launch the application and use adb_gdb_xwalk_core_shell to debug

Debug Java code with Eclipse

  • Import the project into Eclipse workspace:
New -> Android -> Android Project from Existing Code -> point to XwalkCore project root(src/xwalk/runtime/android/core_shell)
  • Add third party dependencies to project
add Java code of xwalk, base, content, ui... to project
  • Launch application to debug, you can use command line to control debug the startup
#In xwview-shell-command-line, write content as follow and push it to device
XWalk --wait-for-java-debugger

Enable Event Tracing on XWalkCoreShell

  1. Launch XWalkCoreShell on Android device
  2. Start and stop tracing recoding by running the commands on host machine:
 adb shell am broadcast -a org.xwalk.core.xwview.shell.GPU_PROFILER_START -e file /sdcard/Download/trace.txt
 adb shell am broadcast -a org.xwalk.core.xwview.shell.GPU_PROFILER_STOP
  1. Run adb pull /sdcard/Download/trace.txt to download the trace.txt to host machine
  2. Open about:tracing in Chrome browser on host machine and load the trace.txt
