it stop at chromiumAndroidDriver._start_once waiting for process start:

self._read_prompt(deadline)

def _read_prompt(self, deadline):

last_char = ''

while True:

current_char = self._server_process.read_stdout(deadline, 1)

if current_char == ' ':

if last_char in ('#', '$'):

return

last_char = current_char

the process start:

proc = self._host.executive.popen(self._cmd, stdin=self._host.executive.PIPE,

stdout=self._host.executive.PIPE,

stderr=self._host.executive.PIPE,

close_fds=close_fds,

env=self._env)

and self._cmd:[u'/full/xiewen06/chromium/src/third_party/android_sdk/public/platform-tools/adb', '-s', android device number, 'shell']

firstly i use autoninja -C out/Default blink_tests, third_party/blink/tools/run_web_tests.py -t Default third_party/blink/web_tests/external/wpt/webrtc, it use content_shell and run well.

and i try to run WPT on android, so i changed args.gn(target_os = "android" target_cpu = "arm64"),and run ninja -C out/Default content_shell_apk. Using 'third_party/blink/tools/run_web_tests.py --android -t Default third_party/blink/web_tests/external/wpt/webrtc', and it said that can't find ContentShell.apk in third_party/out/Release, so i changed out/Default to out/Release, and meet this question.

ContentShell doesn't use WebView - even when running on Android it's just based directly on the Chromium //content layer. So, it's probably better to ask chromium-dev@ about this.
