Tracing on Android touch devices is not as straightforward as on iPads because there is no browser inbuilt console.

There are a few tools to remote debug Webkit browsers. Here we are only going to cover the Android Debug Bridge – adb – which lets you output trace statements to a dos command prompt. To use adb you require:

  • The platform tools included in the Android SDK package: http://developer.android.com/sdk/index.html.  Note: the entire package is quite big, it should be enough to just get the platform tools.
  • A USB connection to a PC or laptop. Check that your device has USB Debugging enabled: Settings – Applications – Development – USB debugging

  1. Connect the device to the computer and open a DOS prompt and change directory to the platform tools.
  2. Type this command and press Enter:
