Currently, it is not possible to add -e debug when Selenium/WebDriver is started on Android device.

Like

$./adb -s <serialId> shell am start -a android.intent.action.MAIN -n org.openqa.selenium.android.app/.MainActivity -e debug true

Provide a switch/configuration/ means that will allow this logging. More details here http://code.google.com/p/selenium/wiki/AndroidDriver
