A memory leak tracking library for Android and Java.
If you are developing an API where your clients must bind and unbind with their observers, then wouldn’t it be better if you could reduce the chance of misuse?
LeakTracker helps detect when your observers aren't unbound properly.
Somewhere in your code store a reference to the tracker. Dependency injection such as Dagger is recommended to inject this instance where it is needed.
val tracker = LeakTracker { exception ->
// Log the exception as you wish
Log.e(LOG_TAG, "Subscription leaked", exception)
}Then in your APIs addObserver/bind/subscribe method use the tracker.subscribe
function to return an Unsubscriber.
@CheckResult
fun addObserver(observer: Observer): Unsubscriber {
// save your observer here
return tracker.subscribe {
// remove your observer here
}
}LeakTracker will automatically call your exception handler when an
Unsubscriber is garbage collected without being called.
