4. Click on "Download" button

I am getting same issue on both Debug and Release mode with fresh "x86 emulator of API 10" with following configuration:

1) Link All | No Shared Runtime | No Fast Deploy
2) Don't Link | No Shared Runtime | No Fast Deploy
3) Link Sdk Only | No Shared Runtime | No Fast Deploy (Default RELEASE)
4) Default debug mode

I've added internet permission to this sample to fix the issue on release configurations in master/12fe747

Akhilesh are you sure the emulator you are deploying to as internet access? I saw the same exception on my x86 emulator and realized it was due to a lack of internet connection.

Now, application does not throw exception on release mode on device/emulator having internet connection.

On x86 and normal emulator of API 18 having internet connection, application is working fine and Download works well.

However, I am still getting same issue on the x86 and normal emulator of API 10 due to a lack of internet connection and I am unable to enable internet on API 10 emulator.

I have tried to enable internet on API 10 emulator but doesn't get success. Please guide us how to enable internet on API 10 emulator.
