I am getting started with Android development. I hope to share my understanding of how to build apps and how things work in Android as I learn more. This is my first post about getting started.

Next, to setup your development environment follow the instructions to install the Android Development Toolkit . The toolkit has a built-in emulator and so it is not necessary to buy an Android device, at least, at this time. You can get started by running your applications in the emulator. 

I was consistently getting this error in chrome for a webpage that was loading just fine in safari. I managed to fix the problem by doing the following in chrome; Go to History > Show Full History Type the site domain to filter the results to show all recent attempts to load the page. Select all entries in filtered results and click "Remove Selected items." In the same History window, select "Settings" from a list menu in the left bar of the page.
