Visual Studio for Mac - Xamarin update to Android O API 26

After the release of Android O, it is not just the hardware manufacturers who are gearing up for a release. There is a list of cross-platform application development platforms which is busy to rollout the upgraded version. Xamarin is no new name in this list.
After upgrading some of the Visual Studio for Mac and other components, the build suddenly fails to load on the emulator. The IDE gives an error similar to the one shown below:

Warning XA0105: The $(TargetFrameworkVersion) for FormsViewGroup.dll (vv8.0) is greater than the $(TargetFrameworkVersion) for your project (v7.1). You need to increase the $(TargetFrameworkVersion) for your project. (XA0105)

After repeated efforts to setup a new AVD for Android O, nothing works at all. Putting some efforts Googling for the issue, the root-cause gets clear.

From Android O onwards, certain tools will stop working and will have to be replaced by their newer counterparts. Xamarin Android Device Manager will replace Google Emulator Manager.

Currently in preview, Android Device Manager or Xamarin Device Manager will replace Google Emulator Manager. The UI looks slick and makes it easy to create and manage AVDs.

However, there was no way to manage system images. That can be done from the SDK manager as Google Emulator Manager stopped working after the update.

Google Emulator Manager can be used with Android SDK Tools v25.2.5 or lower.


Munch your Oreo and share your update experience!

Build Windows 8

Most of us are aware that Microsoft is promoting Windows 8 heavily. Windows 8 adoption is very important for the Redmond based company. Microsoft knows that developers play a very important role in this process. iOS developers have already proved this fact by writing Apple's success story.

Windows 8 - Network Configuration

Microsoft might have given a huge face-lift to its Windows Operating System but the truth is that somewhere somehow it is the same old core with new visual user interface. Many of us who have been running Windows 8 Pro for sometime may tell this easily.

Assembla hit by a virus?

Today hosted task management site Assembla was hit by some virus. Around 3 hours back we got Service Unavailable - DNS failure error when trying to access the portal.
Trying to call any API from Assembla returns with the following unwanted HTML code prepended to the response:
<html><head><meta http-equiv="refresh" content="0; URL=http://sedoparking.com/?path=home"></head><body><a href="http://sedoparking.com/?path=home">Please click here</a></body></html>
We have logged a ticket with them. The response was quick but when we tried to post a reply comment we consistently got error - Your CAPTCHA words didn't match We'll keep on chasing them for updates and hope safety for Assembla users.
