I am trying to run my Android app on Chrome 50 / Windows 7 using ARC Welder beta. It's crashing immediately after I click on 'Test' button of ARC Welder.

I followed the approach mentioned in the docs to capture the app logs.

Though I see log getting started, it doesn't have much info. All I get is:

--------- beginning of main

--------- beginning of system

--------- beginning of crash

I am new to this, can any one help me out on how to get proper app logs?

Try adding this to your manifest using the Additional Metadata option in ARCWelder: {"stderrLog": "V"}

After you've started your app open chrome://inspect/#apps and look for your app.

Click the inspect link and open the console tab.

Type the following command to see the logging: plugin.shell('logcat');

If you have tried collecting stdout and stderr from Chrome/NaCl as suggested in the document, you can actually increase the amount of Native Client’s diagnostic output by setting these environment variables:

  • NACL_PLUGIN_DEBUG=1
  • NACL_SRPC_DEBUG=[1-255] (use a higher number for more verbose debug output)
  • NACLVERBOSITY=[1-255]

You can also redirect stdout and stderr to output files by setting these environment variables:

  • NACL_EXE_STDOUT=c:\nacl_stdout.log
  • NACL_EXE_STDERR=c:\nacl_stderr.log

Furthermore, you can use to redirect Native Client’s internally-generated messages by setting this variable: - NACLLOG=c:\nacl.log

More tools and techniques which you can use to debug are described in Debugging.

  • Sorry your solution is not clear to me. I am not using native client, it's just a simple android apk loaded on ARC welder. – Amit Apr 29 '16 at 09:15
