Handle java.lang.IllegalStateException properly

[ChangshinLee-NBT]

I'm currently using gRPC on Android, and it crashes due to the following exceptions:

Case 1:

Fatal Exception: java.lang.IllegalStateException: activeTransport still points to the delayedTransport. Seems transportShutdown() was not called.
       at com.google.common.base.Preconditions.checkState(Preconditions.java:174)
       at io.grpc.internal.TransportSet$TransportListener.transportTerminated(TransportSet.java:495)
       at io.grpc.okhttp.OkHttpClientTransport$ClientFrameHandler.run(OkHttpClientTransport.java:759)
       at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113)
       at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588)
       at java.lang.Thread.run(Thread.java:818)

Case 2:

Fatal Exception: java.lang.IllegalStateException
       at com.google.common.base.Preconditions.checkState(Preconditions.java:159)
       at io.grpc.internal.DelayedClientTransport.startBackoff(DelayedClientTransport.java:324)

       at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588)
       at java.lang.Thread.run(Thread.java:818)

Is there any way to handle these exceptions before crashing?

Thanks in advance.

Those are bugs. What version of gRPC are you using?

[ChangshinLee-NBT]

I am using 1.0.1.

I have the same problems like yours. And here is another case:
(I am using 1.0.1)

@xuguobiao that looks like a different bug, something with the nano proto encoder.

[xuguobiao]

@carl-mastrangelo could you help me to figure out the crash logs i post in issue #2346. ( proguard, multidex were used in my app). Thank you very much.
