I put every fragment with their own FAB Button. I found that is always placed under the last element of that layout. It won't be pushed further bottom, at the right bottom of the screen. I used to use the LinearLayout and RelativeLayout, they won't work too.
FInally, I found android.support.design.widget.CoordinatorLayout is only way to work, I don't know why yet, I found this solution by trial and error
Yesterday, I found my Outlook is not working anymore. I cannot open it! It stayed in a splash screen,the "processing..." wordings is staying in there. After I did some researches and testing, I found the root cause is from the COM Add-ins for Outlook. To solve this problem, you need to go into the safe mode of outlook, you just need to type "outlook /safe" in "Run...." or command prompt. After you enter safe mode, you need to File->Options->Add-ins->COM-Add-ins->Go
Then you checked all add-ins you do not need to use. Finally, you close your outlook, open it in normal mode again. It will work again.
Yesterday, I went to IKEA in Logan for shopping. I found their product ranges are expanded in the tech side too. There are some wireless chargers. Also, I found this fancy battery charger too. It looks pretty and it can charge ten batteries each times. In addition, it got a digital display which can indicate the charged level of each battery, that looks great! But it costs AUD$40, which is a bit too much for me. I did not buy this.
I started to build a library management system for small organisations. This system doesn't require a pc at all. It will works in any iOS and Android devices. It used a camera in the device as a bar scanner. I used an open source framework ZXing.Net.Mobile to do that. I found when I fire the scanner activity, it got a blank back screen. I initialized the framework
And I gave the camera permission in AndroidManifest.xml, that still got a blank screen.
After I read the document from ZXing.Net.Mobile, it need the flash light. After I gave the flashlight permission, it works.
In ten years ago, we started to use Visual Studio Team Foundation Server. That sounds only a source control system. Last night, I went .net user group meeting for the new version of Visual Studio Team Service. The presentation is great. The new version have on-premise and on the cloud. Moreover, that is more than a source control system. It is similar with JIRA, and it can handle the change request and user story, you can use it to do scrum meeting. In addition, it is not for Visual Studio, it got the plug-in for eclipse and Android Studio. Also, it got build agents for Android and Linux too, even you use the cloud version, you can install a build agent on your computer. The on-cloud service can trigger the agent. Lastly, it just supports TFS, it supports ZGit, and can link up any external git system. That is great!
