Java is obsessed with constants.  And for good reason, I would do something like this:

In Analytics.java:
```java
public static final String ADB_ENABLED = "apk.adbEnabled";
```

To use:
```java
Analytics.sendEvent(Analytics.APK_ENABLED);
```

This way, if you ever need to change the name of that event, you change it in one place and the change is reflected everywhere you use it.
