in your native\assets folder there should be a icudt46l.zip file. If you do not intend on using the JSONStore feature, try deleting this file and re-building your app. This should reduce the filesize considerably, but again I can’t guarantee what happens during runtime (nothing bad should happen…).
Tired of debugging using eclipse ? too much menu or button for you?. Then use this command, it should filter for you the desired package.
# adb logcat | grep `adb shell ps | grep com.my.applicaiton | cut -c10-15`
replace com.my.application with your application package. Make sure you copy the code exactly as it is.
