Most folks are moving over to Android Studio now a days. Eclipse has a way to view Logcat in one of the tabs. Open that and you will see the line number and stack trace.

From the command-line regardless of IDE you can run:

$ANDROID_SDK/platform-tools/adb logcat -v threadtime

When the application crashes you will get a stack trace that tells you the stack at the time of the crash.

Another good option is Crashlyitc because that will give you vision into failures in the field.

If you need an advanced log tool check out http://lograbbit.com

I hope this helps.

I'd recommend switching to Android Studio, and use the logcat output.
