When app crashes you can see two buttons, force stop / OK and report. Click on report button and there you will find various tabs. In one of the tabs you will get stacktrace.

To see logs just use 'adb' tool. Connect device, type in a console:

adb logcat

And launch your app.

And I would recommend you to use some service which logs app crashes and exceptions. For instance https://crashlytics.com
