This is just a simple example (and yes, there are others doing similar). You can modify this example it by using other colors, gradients, adding other views and so on to have a simple but good looking GUI.

Horizontal ScrollPage
I want to share this simple example of an HorizontalScrollView that works like ViewPager. Main difference between this and ViewPager is that HorizzontalScrollview has an only inner panel: this means that you can put inside it views that are larger then page width.

Third party tool for screen recording
I''m mostly using B4A-Bridge to connect the IDE to the Android devices. The built-in video recording feature doesn''t work with B4A-Bridge. I found a good alternative: https://play.google.com/store/apps/details?id=com.hecorat.screenrecorder.free This app, which requires Android 5+, makes it simple to record the screen. You can then use Tools - B4A Bridge - File Explorer to copy the files to the PC. The video files will be under: AzRecorderFree. Combine it with LICEcap (https://www.cockos.com/licecap/) and you can convert it to an animated gif.

Adding Tripod Mode to your DJI Mobile app
Tripod mode for DJI drones, limits the speed of your drone to around 2 mph. So you''re less likely to hit something, when your in confined spaces, or around people. This shows you how to add this to your app. Right now, only the Mavic Pro has Tripod Mode.

SQL Fiddle
There is a very useful online tool called SQL Fiddle that allows you to build test tables, populate them with data & run queries on them. This is great if you are trying to figure out how you should set up a database or if you are having trouble trying to figure out a complex query as it allows you to quickly run tests without having to build & deploy an app to a device or simulator.
