Rare DeadSystemException when device (AndroidTV) goes to sleep

[stari4ek]

Describe the bug I'm seeing rare crashes in Crashlytics with callstack:

java.lang.RuntimeException: android.os.DeadSystemException
    at android.net.ConnectivityManager.getActiveNetworkInfo(ConnectivityManager.java:797)
    at com.github.pwittchen.reactivenetwork.library.rx2.Connectivity.create(Connectivity.java:65)
    at com.github.pwittchen.reactivenetwork.library.rx2.Connectivity.create(Connectivity.java:50)
    at com.github.pwittchen.reactivenetwork.library.rx2.network.observing.strategy.MarshmallowNetworkObservingStrategy$5.onLost(MarshmallowNetworkObservingStrategy.java:165)
    at android.net.ConnectivityManager$CallbackHandler.handleMessage(ConnectivityManager.java:2845)
    at android.os.Handler.dispatchMessage(Handler.java:102)
    at android.os.Looper.loop(Looper.java:154)
    at android.os.HandlerThread.run(HandlerThread.java:61)

Most probably device is going to sleep or power off. And there is network notification dispatched while VM is dying.

Expected behavior It would be nice to catch those errors and route with onError

Device:

• Android: 7.0
• Android Build: SVP4KDTV15_EU-user 7.0 NRD91N.S34 5.433 release-keys
• Manufacturer: Sony
• Model: BRAVIA 4K 2015
• Thread: ConnectivityManager-797

implementation 'com.github.pwittchen:reactivenetwork-rx2:3.0.6'

Hi @stari4ek,

Thanks for reporting this. According to the logs, it may be related to ConnectivityManager.getActiveNetworkInfo() method from Android API, which could throw DeadSystemException. I haven't seen that error before. Maybe catching this error while getting activeNetworkInfo will solve this problem. I'll have a look on that.

Regards, Piotr

Error from the last log looks like it's caused by another library, but general problem is probably the same.

ah. ouch. you're right. Sorry for that
