I want to write a Client on android phone and send an Object to a Server running on my windows PC (using ObjectDecoderInputStream ), but had these Exception

But when I use CompatibleObjectEncoder/Decoder on my phone and ObjectInputStream on my PC, it works fine. And if I change the android code to Java code, and run the client on my PC to send my self the Object using ObjectEncoder and its correlated InputStream, it works fine.
By the way, I use netty 3.6.3 final and my android device is 2.3.7 gingerbread (which uses jre 1.5 or 1.6), my PC is jre 1.7, could that be a problem?
Sounds similair to my problem here - I never got to the bottom of it, but changing the JVM so both ends run the same version stopped the error

I have just received this strange crash report from a user in my Google Play Developer Console.
The app is stable at the moment and this is the first time I have seen this crash. It has been in release for 3/4 months now. The device was a Galaxy S5 running Android Version 5.0.
My initial thoughts is Google Play Services has updated causing issues. Any better offers?

ADDITION Have just found this thread which is about other people experiencing the same crash on Samsung devices.
This was related to issue 8314. This issue has now been fixed via both a Firmware update from Samsung and also an update to Google Play Services.
If this helped you, please mark this as the correct answer.
I have around 100 unit test in my Android project. Everything work perfectly. I use JUnit + Mockito + PowerMock (when dealing with difficult static class).
While writing my latest test, I was surprise with this very strange error that I don't understand.
When I do this in the setUp() function:
playerAccessor = mock(PlayerAccessor.class);
All the tests crash with this very strange error:

My only clue is that the PlayerAccessor have a function called register which take an object Player which implement the OnCompletionListener interface. But I'm not mocking the Player, I'm mocking the PlayerAccessor.
Do I need to specify something in my mock function so it doesn't try to mock every object used by the PlayerAccessor? Is it something missing from my test (import???).
EDIT
One answer suggest me to put the needed library (com.google.android) in the "test" scope but since it's the android library, the scope NEED to be "provided". If I change it, it's true that my unit test start to work but when I run the app, I receive big errors in the console telling me that it's a very bad thing to do to include the android jar... So what are the other solution???
If the class you're mocking imports another class you have to have that class on the classpath or the class loader will fail, regardless whether you're actually using any of the functionality afforded by it.
If you're using maven for builds you can easily add a dependency jar with test scope
Eclipse should respect pom configuration
I'm planning to use GCM features for an Android app. I setup the proper Android app and the backend service deployed on localhost.
Everyting was fine and the notifications were displayed on my testing device. Next I tried to deploy the service on a different server with a real IP. Now I'm getting this strange error when I try to push the notification from the server side and I don't know how to fix it. Does anyone have a solution?

I have an android application that parses the HTML content and displays the required tag.
It is working fine for the hardcoded HTML code.
But when I set up a HTTP connection for a URL, then it is not working in Emulator.

I want to give that response as an input to the parser.
I want it working and parsing in Emulator iteself.
