Crash when trying to connect too fast [UndeliverableException]

See original GitHub issue

lib version 1.5 rx2 I am facing issue in my app and in the sample app but i cannot find where the issue source is.

To reproduce, it’s really easy, you have to try a connection just right after reactivate Bluetooth on the device (about 1 sec after). I think the GATT stack is not really ready but in fact it throw a disconnection although the connection process is not done. it’s seems that a exception is not handle and rx is not happy but i am not sure.

Hello everyone,

I was investigating this issue recently.

The root cause of the problem is the threading of Android OS — callbacks may be called on arbitrary threads. The library does not know how it will be used and thus it is routing errors to all listeners. Because the errors sometimes may be routed through many merged observables they may appear more than once in an observable chain…

One of the differences between RxJava 1 and RxJava 2 is that the former did swallow exceptions that happened after the chain was unsubscribed whereas the latter is throwing an UndeliverableException in this situation. With the current library architecture it is impossible to mitigate this behaviour and the suggested workaround is to add a code similar to what @thuytrinh wrote above:

Kotlin

RxJavaPlugins.setErrorHandler({ error ->
    if (error is UndeliverableException && error.cause is BleException) {
        return // ignore BleExceptions as they were surely delivered at least once
    }
    // add other custom handlers if needed
    throw error
})

Java

RxJavaPlugins.setErrorHandler(error -> {
    if (error instanceof UndeliverableException && error.cause instanceof BleException) {
        return; // ignore BleExceptions as they were surely delivered at least once
    }
    // add other custom handlers if needed
    throw error;
});

We’ve seen these BleDisconnectedExceptions wrapped in UndeliverableException in our projects for a while now, when using RxJava2.

This happens when you dispose of the subscription while a disconnect takes place. The RxAndroidBle code delivers this exception just before your code disposes of the subscription but was about to reach your just-disposed error-handler just after your code disposes of it.

We worked around this by registering an uncaught-exception handler by calling RxJavaPlugins.setErrorHandler and handling the UndeliverableException appropriately. The handler we used just logged the uncaught-exception, but did not let the app crash.
