The only thing you need to do is add the READ_LOGS permission to your manifest.
<manifest ...> ... <uses-permission android:name="android.permission.READ_LOGS"></uses-permission> </manifest>
When you do this, ACRA will automatically add logcat information to your crash reports. The information that is added automatically is similar to the information you get when you run adb logcat -t 200 -v time during a crash.
